Pro is a one-time lifetime purchase that unlocks live currency rates with daily auto-sync, on-demand refresh, and unlimited favorite conversion pairs. All 13 conversion categories are free for everyone. Pricing is displayed in the app before purchase.
Open Settings and tap Restore Purchase. This uses Apple's StoreKit restore flow to reactivate Pro features if you have an existing purchase on your Apple ID.
UnitFlip stores favorites, preferences, and cached rates locally on your device. There are no accounts, no cloud sync, no ads, and no tracking. Conversion inputs are never sent to our server. If you choose to send a bug report, the support service receives your message, optional email, and a one-way IP hash used for rate limiting.
The free tier includes bundled currency rates that ship with the app. Pro can refresh rates from Frankfurter and cache the latest result for offline use. Exchange rates are informational and may not reflect a real-time market quote.
UnitFlip is local-first. Your conversion data stays on your device, with no ads, no tracking, and no third-party SDKs.
