Do not waste your money

The scanning of the test strip does NOT work no matter how you align the strip. Also, very difficult to manually ise the strip as the colors are very hard to match. I ended up taking my water to our local pool company and having an analysis. Turns out I didn’t need half the chemicals this app was trying to sell me.

Let me choose my camera lense

Only chooses .5 lens so I have a difficult time zooming in on the test strip.

Dimensions

We need an option to enter how many gallons the pool holds and not dimensions. I have an 18 foot round pool. When I enter this in, your app says my pool holds 8429 gallons.

Test strips

This is my second time using the test strips. First time was a few days after initial shock treatment. This seems like the best way to go instead of all the fancy devices out there. I will take a sample water to get tested independently just to verify accuracy. I’ll report back.

Reading is wrong sometimes

Taking pictures and sending it sometimes doesn’t match the bottle

History not saving?

All good except history of testing not being saved ( yes signed in to app) except for first test at season start up???

All good but

Wish it would save all test results automatically.

Facil de usar

Round Pool

I have a round pool. There is an option to select a round pool when setting up your app, however-they were then asking me for the width and length of my pool. I cannot give the width and length of a round pool! Your app would not let me continue unless I added this information rendering this app completely useless to me. So frustrating!

Positive review

I really like being able to take a picture of the test strip and have it analyzed for me. I highly recommend.

Varies

You can test the same strip seconds apart and it will give you different results each time

Finally, my pool is under control.

OK, so I keep on running into this problem year after year. I open up my pool and my alkalinity is ridiculous. I’ve tried to handle it several different ways. One year I even went ahead and just drained it and refilled it entirely. That sucked. This year I downloaded the HTH app. I’ve been testing and following the recommendations. My alkalinity is still barely high, but all of my other chemistry is spot on. I do not plan to look at more YouTube videos or ask friends and family and neighbors. The HTH app got me to where I need to be. Thank you!

Test strip

Readings not accurate according to back of tube

Test

The app is awesome and very helpful to get my back on track!

Multiple

I can do a test exactly as instructed to get five minutes later again exactly as instructed to complete opposite different results

Bad batch?

This year I’ve gone through 2 tubes of test strips, because the camera function on the app glitches when it’s time to read the test strip

Do not trust

This may be the most unreliable app in the history of the universe. I checked my water and my free chlorine was high and my alkalinity was high. Two minutes later, I checked it again and my free. Was low and my alkalinity was low. I’ve tested the water several times today and every time I get a very, very different reading.

Terrible

Possibly the worst app ever used

HTH testing not working

Last year app was working no issues with testing HTH strips. I recently started using it again for the season and is not testing is working - does not allow to choose the colors to match test strips- I hope they fit it ASAP. And yes I did the update to the app, still not working.

Great idea, but needs AI integration

It’s good to have a more objective reading of the test strip, as well as ability to archive tests as you work to maintain the water balance.
However, the recommendations seem to ignore the overall picture. If three readings are off, there’s no comprehensive step-by-step, as in, “first add A, then add B 6 hours later after retesting.”
If you add the recommended chemicals all at once, or in the wrong order, you can actually make things worse.
So, until HTH fixes this, I recommend plugging the readings into your AI, which WILL give you much better advice.
