What are your thoughts on pool management apps?

So I've been managing my pool for about a month now. It's been a lot of learning and record keeping and it's been kinda confusing at times.

Do folks have a favorite pool management app? Or how do you keep track of all of the chemicals, dosing, and recurring maintenance, and other tasks?

I found these apps and was curious if folks had any thoughts about them.

• Pool Math: https://www.troublefreepool.com/calc.html
• Pooli: https://pooli.app/
• Orenda: https://www.orendatech.com/pool-dosing-calculator
• FlowBeacon: https://flowbeacon.app/
• Pool Care: https://www.swimuniversity.com/pool-chemical-calcuator-apps/
• Nimbus Pool Doctor: https://apps.apple.com/us/app/pool-doctor/id375459618

The only one I've really tried is Pool Math, but... it gave me a really bad impression because you can only log 1 test. I couldn't even properly evaluate the app because it's so limited. I uninstalled it pretty much immediately after running into that.
