Lately the last month or so weather pic or manual entry once you hit next it closes the app and you have to start over . Very upset as this was the one reason I spent the extra on these strip to keep from going to the pool store for water tests . ### 2/5 — Update crashes *2026-08-04, version 2.0.10* Since update 2.0.10 after strip is read, trying to go to the readings and recommendations page causes the app to crash and force close. iOS 26.5.2. ### 2/5 — Broke recently *2026-08-01, version 2.0.10* I like it, but about a week ago it started crashing every time I try to save a test. Makes it worthless. Please fix! ### 1/5 — Constantly closing/crash after a reading *2026-07-31, version 2.0.10* Non stop crashing and takes forever to read even with the starter kit. ### 1/5 — Does not work *2026-07-31, version 2.0.10* App crashes every single time I try to use it ### 2/5 — Photo capture results crashing *2026-07-31, version 2.0.10* I really love this app, it has been working great so far, but lately every time I do an auto capture of the test strips, and I click next, the app crashes and kicks me out, every single time. I have not been able to get a history for a week now. Please fix!! ### 2/5 — Started good *2026-07-30, version 2.0.10* App started out really good accurate readings then one day it would take the pic then I’d hit next app would shut down tried again same thing has never worked again tried deleting and reloading same thing tried rebooting phone same thing wish they had a fix I really liked this ### 1/5 — Not worth a thing *2026-07-30, version 2.0.10* Bought the steps, test strips and downloaded aqua Check connect. Scanning the test strip is not really easy. You have to get it exactly position correctly and once you scan it, it shows you all your values and there's a button that says "next" when you hit the next button, it closes the app. Totally worthless ### 1/5 — Bad Update *2026-07-30, version 2.0.10* Latest update causes the app to crash when hitting next after capturing the strip. It was ok before. The app was 90% of the reason I purchased this kit. Now it is a week later with multiple reports of the app crashing and I’ve seen no indication anyone is addressing it. ### 1/5 — App keeps closing when I submit test strip *2026-07-29, version 2.0.10* I’ve deleted the app. Reinstalled. Nothing works. I’ve lost my pool history. I take a photo of the test strip but it won’t show what to do after viewing results and won’t save results in my app’s history. The app simply shuts down. Every single time. I’m frustrated. ### 2/5 — Not impressed *2026-07-29, version 2.0.10* Taking a picture of the strip is impossible. It does not work. The test strips do seem to be accurate but the app stopped working. Every time I manually enter in the test strip and push the next button it shuts my app down and does not save my results, I’m not able to use the app because of this. ### 3/5 — Will not save *2026-07-29, version 2.0.10* Currently the app in iOS will not save your tests ### 2/5 — App not working *2026-07-29, version 2.0.10* Latest update closing app after selecting “next” unusable ### 1/5 — Stopped working *2026-07-28, version 2.0.10* Had the app for 2 years and it was fine. Now it keeps booting me out after clicking next on the results screen. Useless now. ### 1/5 — Useless *2026-07-28, version 2.0.10* iPhone 13, downloaded app today, got it to take a picture of the strip, the app closed and didn’t save any of the info I put in it. Thought it was a glitch so I entered the colors manually so it would help me with adjusting what I need to in our pool. When you hit next it closes the app and doesn’t save anything. So it’s getting deleted. ### 1/5 — Doesn’t work *2026-07-27, version 2.0.10* It worked OK the first few times. Now the photo capture isn’t working. It’s fuzzy. And when it does it crashes when I press next to see the summary. Not worth the extra money for the kit. Cheap testing strips work better. ### 1/5 — Waste *2026-07-27, version 2.0.10* These strips were $18.99 and the app doesn’t work. It takes forever to capture the strip, then when you click next the app completely closes out…. Leaving you with nothing. Spend less and get more with a different brand. ### 1/5 — Bad app *2026-07-27, version 2.0.10* Every time I hit next to get the #DATA on my test trip, it closes the app. I’ve tried everything. ## Most critical reviews (10 lowest-rated) ### 1/5 — Terrible *2026-08-23, version 2.1.1* App never works right. So frustrating. Waste of money. ### 1/5 — Useless app *2026-08-19, version 2.1.1* Is this app their way of making us WASTE strips? App won’t read strips. ### 1/5 — App is broken *2026-08-04, version 2.0.10* I haven’t been able to utilize the photo capture all year after 2 years of it working great! Now even the manual input is broken after the last fix! After wasting time entering everything when you hit next it closes! And forget about support, they only provide an old fashion mailing address to contact them. Guess I will need to find a better water test strip company to use! ### 1/5 — App crashing *2026-08-03, version 2.0.10* I’m not sure if the app was updated recently, but as of 8/1/26 the app crashes when entering a strip reading. When you reopen the app, there are no readings stored. ### 1/5 — App is junk *2026-08-03, version 2.0.10* App has never worked downloaded 2 years ago never worked Tried using it today 2 years later still not working hope they fix this issue I have no been able to use my strip with the app ### 1/5 — App doesn’t work *2026-08-03, version 2.0.10* It doesn’t work. The auto capture doesn’t work and the app crashes when you try to manual input. I just uploaded a picture to AI instead since this app is useless. I will not buy these strips again ### 1/5 — The app closes *2026-08-02, version 2.0.10* I have never been able to get a test result due to after taking a picture of my strip or manually putting in the numbers. After doing one of these things the app closes down ### 1/5 — Crashing *2026-08-01, version 2.0.10* App crashes immediately after taking photo. Very disappointed, should’ve went with the cheaper strips. ### 1/5 — App locks up or quits *2026-08-01, version 2.0.10* This app constantly just quits or locks up. It is so inconsistent that it’s annoying, and it’s a waste of money purchasing their overpriced select connect test strips. ### 1/5 — Stopped working *2026-08-01, version 2.0.10* New version just shuts down when you do a reading 😫 ## Most praised reviews (10 highest-rated) ### 5/5 — App crashing *2026-07-28, version 2.0.10* Loved the app, very helpful for a first time spa owner. However, today the app crashes after i enter the readings. I’ve tried deleting and reinstalling but it keeps crashing! ### 5/5 — Why change *2023-10-22* Why change the scanning of the test strip. Worked perfect before. Told me how much chemical to add etc. now I can’t get the app to let me take a pic of the test strip. Continually says can’t read. I liked the old version better. I’m at a loss now ### 5/5 — Very useful for noob and “pro” … *2023-07-24* The in app feedback but seemed to not work not here in feedback - site not found so hopefully this’ll make it to them. — My first pool 8’ round) and testing experience. A bid daunting at first but app helped to wade into things and now a few weeks into it … A feature to show all measurements on same graph and per measurement graph to show a trend and projected reminders - to be created, towards user goals. I’d pay for that - but not subscription please, but like app just the same. ### 5/5 — Needs countdown timer *2023-02-05, version 2.0.2* I love the app, but I found myself juggling apps to be 15 seconds after immersion to take photo reading. A simple countdown from 15 seconds would be great. ### 5/5 — Easy to use *2022-08-18, version 2.0.2* Very easy to use and get readings and track history. ### 5/5 — AquaChek *2022-06-19, version 2.0.2* Very easy to use and amazingly informative. ### 5/5 — This app is…. *2022-05-31, version 2.0.2* This app is amazing! I have got their pool testers and I love how easy it is to use! ### 5/5 — Works great *2022-05-18, version 2.0.2* I’ve only used it a few times so far but it seems to be a great app. Photo is easy to acquire and results are immediate and easy to understand. I do a visual check on the card and it verifies the app results. So far so good. ### 5/5 — Test result recomendations *2022-01-13, version 2.0.1* Before this app I was blind on actions required. Now I have full management control of spa water quality. Love it ### 5/5 — Love it! *2021-10-07, version 2.0.1* This app is fantastic! It’s taken all the guess work out of balancing the chemicals in my hot tub. Highly recommend the app and test strips! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
