Last verified: July 2026. Subby details from its App Store listing (Subscription Tracker: Subby, id6739703718). Its privacy label states the developer collects no data. “Not listed” means a feature isn’t advertised on Subby’s App Store page (public listing, not hands-on testing).
Privacy — a near tie
Both apps are about as private as a tracker gets: no bank connection, no account, data on your iPhone. Subby’s App Store privacy label goes as far as “the developer does not collect any data.” TrialBell is on-device with optional iCloud Backup in your own iCloud. If privacy is your only criterion, you can’t go wrong with either.
Where they differ
Subby leans simple and cheap, with a nice touch for people who pay for services in different currencies — it converts everything to yours. TrialBell leans protective: it’s built around the cancel-by date with a lead reminder and a final-day alert, ships 42 one-tap cancellation links and 130 templates, and tracks recurring bills alongside subscriptions.
Pricing
Subby is about $9.99; TrialBell is free for up to 3 and $19.99 once. Subby is the cheaper option; TrialBell asks more, once, for the free-trial machinery and cancellation links.
