As an experiment I recently switched from iPhone (last 10 years?) to Android. It's been a little painful but:
- nearly all apps support Android as well. The ones I used (navionics, banking apps, WhatsApp) you just log in on Android, no cost involved.
- most Apple first party apps have a Google equivalent (google wallet, google keep notes, google messaging etc.) that is very similar
- my AirPods work equally well with android
