I've been "with" IsoTimer ever since I turned in my Blackberry. seems to have lost the ability to obey the same settings that I've been setting for a decade (!) but I had to break up with isoTimer when she refused any longer to be a local calendar and not sync with either my Android 🗓 or my other local calendars; other refusals were annoying - refusal to skip the goals aspect of the Ap; refusal to use its own IsoTimer reminder tone which iselect;etc. This. was. Terminal.

I've been using this app for a long while now (since "isotimer"). The "foundational design" is exceptional but for some reason it has always been problematic. I'm sure many of us don't even mind paying much more for it if only it'll just work without annoying seemingly "unprofessional bugs". I WILL NO LONGER USE THIS AGAIN but I will leave the 5* rating because I see so much potential in it, this could literally take over the world if it was given enough attention and handled more diligently!

I've been noticing for a while (several months now) that I set reminders but don't get any reminder notifications (app notif are on in my phone settings and reminders are enabled in app). Please fix. I will then give it 5 stars again. The week view is EXACTLY as I like it. Free version also allows for nice customization (like dark mode). Cannot find another app that comes close. And I looked!
