There’s one thing I haven’t figured out though…how can I delete a water test? ### 2/5 — Doesn’t do much *2026-08-17, version 8.0.9* Would be great if the product could set reminders for last time, the frog ease product was replaced, last time a frog maintain was added to the water, etc. ### 4/5 — Can’t make it work *2026-07-25, version 8.0.9* Won’t let me finish after fill date screen just deleted it :( ### 4/5 — Frog App *2026-06-16, version 8.0.8* The App should have a reminder to replace the chlorine cartridges ### 3/5 — Confusing Instructions *2026-05-03, version 8.0.6* I always use the app and have never had a problem understanding the instructions on how to fix my water. UNTIL NOW. this time it says “.75 FROG DropH Alkalinity and ph decreaser”. Does that mean .75 of each? And why did you change from Alkalinity Increaser? That’s what I was told to use when I bought the hot tub years ago. technology is great but it’s interesting when companies change these just to change them. ### 4/5 — Maintenance records *2026-04-10, version 8.0.6* Nice that the app records water testing history but what would make the app even better is if it recorded & kept a history of water change interval dates ### 3/5 — Great test based treatment info. Buggy UI. *2026-03-11, version 8.0.6* Every time the app starts up it’s frozen on the dealer page with a dynamic touch response “test” button. I have to wait a good 20-30 seconds just to use the app. Very pointless considering the app is mainly for “testing”. I love Frog products, but this app does not reflect the brand well. ### 4/5 — Got a response *2026-01-30, version 8.0.6* This app used to have a feature that used your camera to take a picture of the test strip and analyze it. Developer responded that the camera feature was not accurate and They are looking at future improvements ### 4/5 — Every time you update the app *2025-12-31, version 8.0.6* I get logged out and lose ALL OF MY HISTORY and my log in doesn’t work anymore so I have to “start again” and set up my hot tub. Other than that I love this app. I rely on this app to help me keep my spa in good working condition. ### 2/5 — Update is downgrade *2025-12-30, version 8.0.6* It used to tell you what to add and how much to balance your water like ph up or alkalinity increaser. Now it doesn’t. Just says your water isn’t balanced. I liked it much better before ### 3/5 — Crash *2025-10-21, version 8.0* Can’t do anything bc the app keeps crashing ### 1/5 — Bad and bad update *2025-10-20, version 8.0* The old app was not very functional so I removed. This app is buggy. Anytime a screen is edited it gives me a black screen. Close and open the app does not help ### 1/5 — New version of the app is nonfunctional *2025-10-20, version 8.0* New version doesn’t work at all. After logging in, it takes you to a profile page, and when you tab the back arrow, it’s just a black screen. ### 2/5 — Why do you need phone & address *2025-10-20, version 8.0* With the latest update, I don’t understand why you need my phone # & address just to check my water balance. It seems to me to be an unnecessary privacy risk. ### 2/5 — Buggy *2025-09-20, version 7.4* Most of the time this app returns errors. ### 3/5 — Update Worse *2025-08-06, version 7.4* The app upgrade made it mostly no use as the camera no longer reads the strips giving error message whether direct photo or using photo from file. When it does work it provides the same solution to increase alkalinity ### 1/5 — Strip Analysis Doesn’t Work *2025-07-28, version 7.4* Tried using this app to analyze the test strips that come with the frog system, by taking a photo and uploading a photo. Get an error every single time. It’s never worked. Tried the ‘diagnose a problem’ wizard, and no matter which problem I select, I get “Error - no solution found.” smh ## Most critical reviews (10 lowest-rated) ### 1/5 — Not working *2026-07-19, version 8.0.9* Every time I attempt to open the app, it asked me to set up a new profile. Somethings wrong. The app has never been that good and I just thought I’d try it out again today. Since I can’t get onto the app, I can’t give it a review. ### 1/5 — Maintenance schedule missing!! *2026-06-21, version 8.0.8* Why would you have an app that doesn’t help track your maintenance schedule and reminders to change cartridges??? ### 1/5 — Why use it? I can read a strip *2026-06-11, version 8.0.8* There is no place to track dates of chlorine cartridges mineral replacement. Also would be great to have water check/replacement reminders ### 1/5 — Used to be helpful now it’s useless *2026-06-07, version 8.0.8* This used to be a super helpful app for balancing your water, especially if using a frog floater with it. It would tell you exactly how much sodium bicarbonate, hardness increased, etc to add. Just opened it for the new season and it’s completely different and useless. Feels like they let ChatGPT rewrite it. It says to add chlorine before balancing? I’ve never heard this in years of owning a pool, and basic research tells me this is wrong. Just for further info, I filled I up the test info and said yes my chlorine was a normal level. Test results come back and say “ok open the frog another click”. Ummmn that is not going to help me when my tap water is 20ppm hardness and I need to add around a pound or so of calcium carbonate? Idk guess this is the death of what was a genuinely helpful app. Def will be looking up my own calculations and won’t be buying frog floaters going forward. ### 1/5 — Sucks *2026-05-22, version 8.0.8* This app sucks ### 1/5 — Needs help! *2026-01-20, version 8.0.6* I’m not sure what use this app is. It doesn’t allow you to upload an image of the test strip. It seemingly serves a limited purpose. I should be able to take a photo of my test strip and it analyzes the colors itself. the bottle already has the same color match chart. ### 1/5 — No reminder? *2025-12-28, version 8.0.6* This app claims to tell you when to change your chlor ball. I can’t even find a calendar showing when I put the new ones on. This app is garbage ### 1/5 — I hate this app *2025-12-13, version 8.0.5* I just want to check my pool chemistry with the app Every time I have to jump through a bunch of hoops to try to sign in why do I have to sign in to check Pool chemistry? It doesn’t make any sense. Take away that requirement to sign in and you would get five stars the way it is I don’t wanna have to deal with signing in to check chemistry ### 1/5 — Canceled *2025-10-31, version 8.0.2* Your insistence on personal information in newest release is a bad ask. Your no-option reminders / notifications / where to purchase supplies isn’t welcomed. ### 1/5 — Ruined! *2025-10-30, version 8.0.2* What did you do to this app!! I can’t set up a profile. I can’t access it and all my spa info is in here. ## Most praised reviews (10 highest-rated) ### 5/5 — FANTASTIC *2026-03-10, version 8.0.6* This app is a game changer when it comes to balancing the chemicals in your hot tub water. It makes it so easy. It tells you exactly what chemicals you need and how much you need. Thank you for making this so user friendly. ### 5/5 — So much better *2025-11-15, version 8.0.4* Thank you for fixing!! I rely on this app and it’s great now!! ### 5/5 — I really enjoy the product *2025-08-23, version 7.4* It really works good drop it in set it how many gallons are Spa is when you don’t use it the Spa just shut the ball off and relax very clean crystal clear and very soothing when you get in I enjoy it very much!! ### 5/5 — Use AI apps to review your samples *2025-05-11, version 7.4* This app works okay. But it won’t read my samples. I take a picture with an AI app and compare it with that and it works amazing. ### 5/5 — App does not work *2025-03-12, version 7.4* Does not work with purple strips ### 5/5 — So easy to use *2024-05-09, version 7.1* Testing my hot tub water used to be a chemistry experiment. This app makes it so easy to keep the water clear and aligned. I manually enter the color from the test strip and quickly diagnose the water. Love it! ### 5/5 — Frog ease! *2023-10-30, version 6.7* This is the perfect way of managing your hot tub ### 5/5 — Love this app *2023-02-08* Came back to the Frog system after doing other chemicals for many years. The Frog system is greatly improved and their app is fantastic. Their customer service has been phenomenal on the phone when I called I highly recommend this product for people who want to have a easy to take care of water, testing, and treatment for their hot tub. ### 5/5 — Step by step to perfect water! *2022-08-06* Frog pool tender and this app made pool set up simple and taught me about pool care one step at a time. It was easy with the included test strips and a little googling to find the chemicals I was told to add in the amounts I was told too. Within a few days everything was dialed in and has continued to be. We love the mineral pool! More than salt and way more than chlorine. ### 5/5 — Love this app, makes it easy! *2022-07-17, version 6.2* I’m all about easy, the frog system and using this app has made it simple --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
