What non-game paid apps do you use that are worthwhile and still relevant in 2023?
For context, I have a decent amount of Google Play credit thanks to Opinion Rewards and a gift card. I'm not looking to start a book or movie collection there, nor sign up for subscription services. But I'm happy to buy the paid/pro version of useful apps.
I'm excluding games just because that's a whole topic on its own.
Here are some one-time paid apps I've been happy with:
Titanium Backup became worthless when split APKs became a thing after it stopped updating. Looks like oandbackup claims to support them, but I see an open issue about some split APK apps not working after a restore (which is what TiBu did)
Edit: So in the spirit of OPs question, an app I gladly paid for was Swift Backup
