Ratings and reviews

This is an amazingly good app. I wasn't quite sure given some of the reviews whether this was going to work for me but it does exactly what I need it to do. It accurately calculates LSI, provides a plethora of explanations and additional information, requires no permissions, and retains all of my previously entered data. The volume estimator was within a 100 gallons on my weird shaped pool. 11,200 vs 11,100 actual. I don't know what else I could ask for. Excellent effort.

Used to provide a calculation of ingredients to add,the exact measurements. Now all it does is try to sell their products and doesnt calculate general ingredients like chlorine/bromine, etc

App still will not work without access to my photos, media and file despite notice that "Pure Planet Science & Technology, Inc. 10/7/19 We don't want access. That was an error that we had to hire better developers to figure out. We didn't realize it was happening, and when we did, it took a long time to solve. Turns out it was something buried deep within the code about how we save and share dosing results. Should be fixed now."
