Anyone know of any good digital logbooks that work with Android, Windows/browser, AND iPad? I'm starting at a regional but am having trouble finding a good one that works with all three. I am an Android user, but still have the iPad the company provides. Thanks!

Deleted. Didn’t realize APDL isn’t on Android

Logbook Pro and Logbook Pro Mobile combo. If you deal with not using Android for any logbook book, APDL on your IPAD is great with Logbook Pro on PC.

I've used Safelog for over a decade Safelog FAA and EASA Pilot Logbook System

Works on all the major platforms and web. I use it on my android phone, my ipad and my desktop through the app or the web.
