There was some difficulty getting it up and running but I’ve since purchased a second one for the spa in August of 24’ and that was up and running in 15 minutes—hardware upgrades and user familiarity making the difference. The countless trips and hours to the pool store for water testing are over as Sutro helps keep my water crystal clear with three reading a day. Love being able to check the app anytime to see what’s happening. To me, the $29 monthly cartridge and monitoring fee in addition to the $350 device cost, are well worth the saved trips to my local pool store. Sutro Customer Service (shoutout Dave!) has been great—always providing step by step instructions that solved any questions that I had. ### 5/5 — My Pool looks better than the rest… *2024-11-13, version 1.84* This device and service allows me keep my pool in such excellent condition that makes the neighbors jealous… The app gives perfect chemical recommendations every time, three times a day… ### 5/5 — Satisfied Customer *2024-11-12, version 1.84* This has been a great product considering the X3 per day water test. Just like everything, nothing is perfect and at times there may be fluctuations in reading but the support and 2 way communication has been great! I would definitely recommend this product to any DIY pool care person. ### 5/5 — New pool owner *2024-10-23, version 1.84* I’m a new pool owner for almost a year now. I was given a lot of information from a lot of people that have pools and service pools the information I received was good. Just didn’t know how to put everything together after purchasing the Sutro. It all made sense. I would water test from Leslie‘s pools, just to make sure the Sutro works. It was spot on which help me service my pool Weekly myself I have never had a pool service with weekly maintenance. My pool has been very excellent condition. If you’re worried that your pool will go wrong purchasing this unit. I will assure you it will give you the confidence you need. Thank you, Bobby ### 5/5 — Awesome service! *2024-10-10, version 1.84* This testing system is awesome. Highly recommend! ### 5/5 — Sutro App *2024-10-09, version 1.84* The Sutro App makes it easy to know that the chemicals in my pool are accurate. The app is easy to use and gives me all the details right in the palm of my hand. ### 5/5 — Great pool app *2024-10-07, version 1.84* We have used the Sutro app for several years now, for both our pool and hot tub, and we love it. Very helpful customer service if you do need to call in for anything. It’s a very easy app to follow and adjust your chlorine. And we love how accurate the readings are. ### 5/5 — Satisfied Customer *2024-09-24, version 1.84* I rarely write reviews, but Sutro exceeded my expectations. As a long-time customer, they have made pool maintenance easy and cost-effective for me. I faced a syncing issue with the hub and charger, despite being near my WiFi. I contacted Sutro customer service through FB Messenger (my usual way of contacting them, fund it the easier way to communicate with them) and I also called their phone number listed on their site. I had to leave a message not realizing it was after work hours on a Friday evening, Jawad called back 15 minutes after I had left that message and helped solve my problem. This excellent customer service ensures I'll remain a loyal customer. ### 5/5 — Solid app and product - much improved over the years *2024-09-20, version 1.84* I’ve been a Sutro customer for over two years. I appreciate the updates the team has made to the reliability and functionality in the app over time, as well as the responsiveness of support when issues have come up. Very happy with the current iteration of the app and the performance of the testing. I spot-check against my Taylor test kit occasionally and Sutros readings are very accurate. ### 5/5 — From Pool Doubts to Crystal Clear Waters – Sutro Makes Maintenance Easy with Top-Notch Support! *2024-09-13, version 1.84* I cannot recommend Sutro enough! As a first-time pool owner, I was hesitant to get a pool because of all the horror stories I'd heard about how difficult and time-consuming pool maintenance can be. My wife and I were close to not moving forward with the installation because of all the warnings from friends and family. People told us maintaining a pool is a nightmare, and many even said if they could do it all over again, they wouldn’t get a pool at all. But then we found Sutro—and I can honestly say it has changed everything. This company and their product have made pool care so effortless that it almost feels like cheating. Whether you're a new pool owner like me or a seasoned pro, Sutro is for everyone. The product takes all the guesswork out of pool maintenance, and it's incredibly easy to use. My pool has been pristine all season long, and I’ve barely had to think about it! What truly sets Sutro apart, though, is their customer service. The team is absolutely second to none. Every time I’ve had a question or needed guidance, their response has been prompt, thorough, and incredibly helpful. It genuinely feels like they treat every customer as their most important one, which is rare to find these days. I wish more companies operated with this level of care and professionalism. I want to personally thank the Sutro team for their dedication to both the product and their customers. If I could stand on top of a mountain and shout for everyone to use this product, I would! Sutro has made my first pool season a breeze, and I’m excited to continue using it for many more seasons to come. Thank you, Sutro, for being an excellent company with an even more excellent product! ### 5/5 — Sutro application *2024-09-06, version 1.83* The process was so easy and J was understanding. ### 5/5 — Great Device!! *2024-09-04, version 1.83* I love the device. Makes pool maintenance so easy and tell you exactly how much chemicals to use. Saves money by not having to pay a pool maintenance company. ### 5/5 — Levels the field for the color blind. *2024-08-24, version 1.81* I had issues using the standard test as i am color blind. Sutro has given me a greater level of confidence that my chemistry is correct. Not only does it test, but it tells you what actions you need to take to balance your chemistry.👍👍 ### 5/5 — Great all around *2024-08-21, version 1.81* Product is great, easy to use. Customer service has been easy to deal with and quickly resolved any issues. ### 5/5 — My sutro *2024-08-19, version 1.81* This pool monitor is awesome it really works well as well be accurate.The notification help to my pool balance more than ever.There service department responds very well to all my questions. ### 5/5 — Easy Pool Care *2024-08-19, version 1.81* Very easy setup and great customer service. ### 5/5 — Sutro Pool Monitor *2024-08-16, version 1.81* I recently parted ways with my pool cleaner, and chose the Sutro to help monitor and guide my pool maintenance. I took a sample to Leslie’s before starting to find out that my pool metrics were way off the charts despite the pool being clean and blue (pH, chlorine and alkalinity were all way too high). The Sutro app has been giving me up to date daily readings and provides me with updated changes based on recommended chemical additions and portions and now all of my metrics are where they are supposed to be. I highly recommend this monitor. ### 5/5 — Sutro works great *2024-08-15, version 1.81* I've used this device for several years now and it has made keeping my pool chemistry in line so simple! Highly recommend it to those who have little time and just need to know what, when, and how much to add to their pools. ## Most critical reviews (10 lowest-rated) ### 1/5 — App worries me *2025-01-22, version 1.84* This is an expensive item to not have the app work. The save button on the manually added chemicals page doesn’t work. I can’t even use this without it. I’m going to have to return it if the app doesn’t work. ### 1/5 — Doesn’t load anymore *2024-09-02, version 1.83* Since the last update for multiple homes, I just see a spinning wheel and my data doesn’t load up. ### 1/5 — Horrible Customer Service *2024-05-20* I have owned this device for two years and I’ve had nothing but problems this year. I have reached out to the customer service team over four times in the last week and now no one is getting back to me. The problem is the app doesn’t work or the cartridge doesn’t work and you need them to do a reset in order for it to work. You can’t get a hold of them so you cannot get them to do a restart. I will be moving to WaterGuru as soon as they come out with a bromine approved device. ### 1/5 — P.o.s. Piece of Sutro *2023-10-08, version 1.80* This thing hardly ever works. I have never, ever, in my life used a device that has had so many issues. If the hub hasn’t disconnects itself from the WiFi then the chemicals in the cartridge is bad, or just the cartridge itself is bad, or something happened to the cartridge when you tried to change it, or air bubbles somehow got into the system. If all those things haven’t occurred then get ready for all the issues with the app, it works correctly about 10% of the time. Unfortunately when this thing does work it takes all the guesswork out of balancing your chemicals. I just wish that was the norm. It is really like someone had a million dollar idea and only had $100 to develop it. ### 1/5 — Nothing works after update to 1.79 *2023-07-23, version 1.79* After my app updated to 1.79, everything has stopped working correctly. The app showed a notification that the hub was disconnected, and I followed the steps to reconnect it multiple times with no luck. When I get to the point to connect to wifi, either the network doesn’t show up or the ‘Change WiFi’ page just shows up blank and the app freezes. For now, my hub and monitor are completely unusable since it’s also telling me calibration is needed after already going thru the process, getting all 3 green checks, and then a message saying calibration failed. I’ve tried deleting and reinstalling the app. I’ve tried leaving the hub and monitor unpowered overnight. Ive verified 5 ghz disabled on network. I’ve reset our modem/router. No luck. I’ll also add I tried to use the new support feature of 1.79 and even that didn’t work. Fortunately, I had the Sutro support email saved, but have not heard back yet. ### 1/5 — I am done with sutro. *2023-05-26, version 1.78* Just like another reviewer I have packages of cartridges laying around that will end up in trash. You have to pay monthly fee to have sutro test your water. So when the thing does not test and has hardware and connection issues - you still get deliveries. Hub keeps disconnecting from my network and sutro randomly stops working. Out of over two years I had it - it maybe worked flawlessly few months. I also had the unit replaced once ( that took long time via email with support) so I am done with it. I work in IT and I am a tester - this should have been user tested for a good while before selling to customer. I am beyond upset and frustrated at the amount of money and time I wasted on this - trying to reconnect it to my network and keep getting errors. It’s a great device in theory and when it works. Unfortunately it mostly has issues.. ### 1/5 — Unable to connect *2023-05-26* Just got mine in the mail. The setup process goes ok until I click Connect to connect the hub to my local wifi the then the app screen goes blank and never returns. I have lots of smart home technology and I had a PHin for 3 years and I can’t get past step 1 on this thing. The other reviewers are not giving me confidence that I will be successful. I’ve emailed support but no response yet. I hope this isn’t a $500 lesson in disappointment. ### 1/5 — Wish I had my time back… *2023-05-25, version 1.77* I’ve spent more time trying to set this thing up than I would have saved using it. I have a house full of smart home technology and automations so I am no stranger to how the process should work. To charge the premium that they do (cost plus monthly), the setup experience must be dialed in. Instead, it’s a head banger. On a positive note, the design of the product and the packaging is fantastic. It’s never easy having electronics floating around but Sutro’s design takes all doubt away. It’s a solid design! I am returning mine as I have realized the traditional process is super simple already and it has never gotten under my skin. The Sutro on the other hand……. ### 1/5 — They don’t care about their customers *2023-03-24* This product seemed like such a good idea but the support ruined it. They spent 6 weeks trouble shooting with me when they could see my Sutro wasn’t taking readings. They refused to send me a new unit but just wanted to keep trouble shooting. They even had me take the entire piece of hardware apart. The app itself crashes and hangs regularly when changing the cartridge and doesn’t always match the manual testing. ### 1/5 — RIP OFF *2023-02-25, version 1.76* SPEND $500 TO PAY $29-$39 A MONTH FOR AN APP. I RETURNED BOTH I BOUGHT FOR MY SWIM SPA. I NEVER BOUGHT A PRODUCT THAT ATTEMPTED SUCH A GREEDY TACTIC FOR AN APP. I HOPE WHOEVER MADE THAT DECISION LOSSES A LOT OF MONEY WHEN THE COMPANY GOES UNDER. SHOULDN'T TAKE LONG…. ## Most praised reviews (10 highest-rated) ### 5/5 — Returning customer *2025-03-24, version 1.85* Has Sutro in my old pool, moved and built a new pool. Lost the hub but just got a new one and back with it. Customer support was great and understanding. Got my new hub and a brand new set of batteries. ### 5/5 — Amazing Customer Service *2025-03-19, version 1.85* I’ve be using Sutro now for 2 years and love it. If I have ever had any issues they have been super helpful fixing it. I wish all customer services were as good as Sutro. The app is very easy to use and has made my pool experience simple. ### 5/5 — Awesome! *2025-03-04, version 1.85* Great app! They are constantly improving and adding new features! Makes it easy to manage my pool hassle free. ### 5/5 — Great app and robot *2025-02-12, version 1.85* Love my Sutro so far and the app works perfect with it. So much less stress by the hot tub!! ### 5/5 — Exceptional Customer Care and Great Product *2025-01-10, version 1.84* I recently purchased the Sutro monitor for my spa and began the setup today. Not being particularly tech savvy, I was experiencing difficulty in getting the app and phone settings, etc. correct to complete the process. I emailed customer care, asking a few questions and Jenna was quick to offer phone support. She called me promptly and was very helpful, kind and polite. Her directions were clear and easy to follow. She continued following me through the process until connectivity was obtained. What a relief! In addition, I asked Jenna a question regarding service that required a further answer from another team member. Within minutes I received a call from Jawad to address my question. Not only did he address that question, but during the course of that conversation he noticed my monitor was not sending a signal to the hub. With the same care as Jenna, he walked me through getting it quickly restored. Within a short time, my app was sending me test results in real time. I am impressed with a company that you can actually have a conversation and they care about helping you. Rare today! I am impressed with the app and monitor. Really cool system. ### 5/5 — Aj *2024-12-31, version 1.84* I love the Sutro app it’s very user friendly. ### 5/5 — Huge win for Hot Tub! *2024-12-13, version 1.84* We purchased our hot tub almost four years ago & I spent several months trying to get the chemistry right on my own, then trying another brand of monitoring (which had a lot of issues & bad customer support). I read about Sutro and its high quality device and gave it a try. I’m sure glad I did! The device is great, easy to change cartridges and extremely accurate (I continue to test manually every couple of months with my Taylor lab kit, just to be sure of my readings). Their customer support is fantastic- highly responsive and very helpful. I highly recommend this! ### 5/5 — Great Way To Keep Your Pool In Tip Top Shape *2024-12-12, version 1.84* Sutro has been my go-to for monitoring my pool water chemistry since the beginning. I’ve invested in their monitor and Pool device, and it’s been an excellent decision. I can confidently check my chemical levels three times a day, knowing that I’m getting accurate readings. Sutro’s device has been reliable and consistent, allowing me to stay on top of my pool’s chemistry without any worries. It’s been a huge relief, and I highly recommend their products. The company itself is great, and the customer support is top-notch. ### 5/5 — Great Pool Product *2024-12-10, version 1.84* This product is highly recommended to balance your Pool Chemical needs. Using this Sutro product for years now and my pool water has been looking cleaner than ever before. ### 5/5 — Makes pool care a lot easier *2024-11-14, version 1.84* The monitor helps to keep the pool water in the correct ph range , chlorine, and alkalinity. The customer service is top notch. Every time I’ve had an issue with the monitor they always take care of me! The app has continued to get better and better also. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
