If I remember correctly I started deGoogling "seriously" in the last summer. At this point YouTube and Youtube Music are the only Google products/services I still use daily but only on PC. I never use them on phone. I also am quite forced to use Gmail sometimes but otherwise I avoid it like a plague.
I think my phone is as deGoogled as possible without rooting and/or changing the OS. I have uninstalled every Google app that I have been able to uninstall and also I have disabled every Google service that is possible to disable. I still have to deMicrosoft my PC. I want to move to Linux but I have understood that there's some compatibility issues with Reaper and virtual instruments. That's the only reason I haven't done it yet.
Anyway. Here is a list of apps/services I use instead of Google's sh*t:
- Browser: Waterfox on PC and Ironfox on phone (of course both with uBlock Origin)
- Cloud storage: Proton Drive
- Email: Proton Mail
- Calendar: Proton Calendar
- Authenticator: Aegis
- Map: OsmAnd
- Search engine: DuckDuckGo and Brave Search
- Play Store: Droid-ify and Aurora Store (not signed in)
- Speech Recognition & Synthesis: SherpaTTS
- Find My Device: FindMyDevice (FOSS)
I think that's all. There's some other FOSS apps and services that I use but they are not exactly replacements for Google's sh*t.
