Recently CamScanner has become annoying with ads and popups. So looking for an alternative document scanner on Android, hopefully with these features:
Anti-shake (what I really liked on CamScanner: when you click, it won't take photo until phone becomes still, so reduces blurry images)
- Upload to Dropbox.
- No monthly subscription (one-time purchase is okay).
Optional (nice to have):
- It's own cloud sync (CamScanner has 400 MB free cloud sync). I find this useful because you can access your scans from the computer automatically (without uploading to Dropbox).
