Basic calendar app that works with your phone's local calendars. You can schedule events, set reminders, view monthly, weekly, daily, etc., handle multiple event types, all the usual things you want to use a calendar for on your phone. No ads, no tracking. Since it works on local calendars, you can use another app like DAVx5 to sync with an online service of your choice.

I've been relying on Google Calendar for years. It works well, but I got tired of its limitations. Particularly, the look of the calendar widget. I couldn't make the background white or black... or any other color than a sickly light blue. Unfortunately, there aren't many options for creating the aesthetic you want. To make a long story short, I tried several cal/dav apps before I found one that worked perfectly for me. It's this one. Fossify. Thank you.

I really like the app but there are a few things to get cleaned up before 5 stars. One, the font, for the bottom event filter, is too large and therefore gets cut off. Two, add an option to be able to pick a snooze time, once snooze is hit on the notification panel. Three, birthdays are getting doubled up. it's showing birthdays from contacts, which I want, but also showing birthdays for my default event calendar. The contacts birthdays should be the only ones showing. Please fix
