This is a great resource. I challenge ANYONE, even those who have maintained pools in the past, not to learn something new from SWIM UNIVERSITY. I am an athletic senior who loves the challenge of maintaining every aspect of a pool. While this is my first salt water pool, I intend to use the app as the handbook (PDF version) was so helpful. The builder is handing this off to me shortly and honestly between the dirty pump basket and filter they "claim" they are maintaining, I can't wait to take care of this baby here in Florida. My work-out trainer uses SU as well...so word will be passed to all. Thank you Matt.

I never have known what elements or how much to add to get within range. Now I can know. And I can confirm what my pool store analysis reads. This app is so amazing! I like the sliders too!

purchased the electronic version of the pool handbook and it has made a WORLD of difference in my understanding of my new pool. Matt and his book are a lifesaver. I also signed up for his app to tell you the chemicals and amounts to use based on water readings. It's awesome!!

Super simple to use. Looks nice. Allows for record keeping in a handy way where it’s always accessible.

I like that I can now re-arrange the testing strip to fit my needs. I like the recommendations for treatment. I also like the timing of chemicals and the gaps between. I like the straightforward nature of the app and its simplicity. Keep up the good work. I am looking forward to continuing the pool journey with you.

Nice app. I had created years ago an excel sheet that captures this info to save week to week. This app provides that - much more convenient. I've used twice so far (I test 2x/wk). NOTE: TA, CA, CH line 'overruns' the ideal/ppm line and cannot read it. Finally, I have a salt water pool - it's great to add "salt mg/L" line so we can capture that info too on the app.

Having the exact directions of what chemicals needed to be added. Ease of input. And the helpful hints in the app are a big help. Love being able to track chemicals used and levels throughout the pool season.

I think the app is awesome! I love the look of it, the ease of use, and the way everything is presented. It’s definitely something that I could find myself using to test my water each week. Thank you for creating such an amazing resource! Looking forward to regularly using the app as well!
