DontCallMe

Tired of spam calls? DontCallMe blocks and flags unwanted calls – no account, no ads, and no touching your data. WHAT NOBODY ELSE DOES Point the app at your very own list – e.g. a CSV file on GitHub – or use the community's. You decide exactly which numbers get blocked. None of the big spam blockers let you do that. OPEN AND TRANSPARENT The community list is public. Anyone can view, audit and contribute to it at dontcallme.eu, where you can also look up numbers for free and report spam. PRIVATE TO THE CORE • No account, no ads, no tracking • Your contacts are never uploaded • The numbers that call you never leave your phone – all screening happens on the device HOW IT WORKS 1. Pick a list: the community's or your own 2. The app fetches the list and keeps it updated automatically 3. Calls from numbers on the list are blocked or flagged The app uses iOS's built-in call blocking: the list is loaded into the system and iOS does the blocking itself – fast and battery-friendly. HONESTLY We're new. Our list is smaller than the global giants' – but it's open, it grows with the community, and you can always use your own. And since iOS doesn't allow showing names for unknown callers, we don't promise "live caller ID" – we just block and flag, reliably. The app collects no personal data.

Verdict
The clearest difference is price: DontCallMe at Free against USB Mobile Disk's $0.99. DontCallMe also leads on ads (none vs shown). USB Mobile Disk's advantage is iOS requirement (12.0 vs 15.0). On in-app purchases and device support there is nothing between them.
