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.

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."

It does calculate the LSI and gives dosage suggestions but it requires to enter your targets everytime again. It also doesn't remember the last test result. So every time you have to adjust all numbers of both the actual and the target.
