Best Log Keeping Smartphone App?

[iTzJu]

Does anyone use a log keeping application on your smartphone to keep track of water parameters, changes, etc...? if so, what's the name of the app and what are your experience with it?

or do you guys think a notebook and pencil is still the best method?

There are obvious advantages to both but I still use pad and pencil.

I’m an old fart, so my “app” is a Bic pen and a bound notebook. My biggest problem is finding the notebook from week to week. I just need to find a permanent spot for it.

I use Aquarium Log for android and it is ok. Recently ive started to use a dry eraser board that I hung up by my sump to jot down notes about filter changes, pareters, qt, etc and ive found it to be handy.
