Common topics
- Timezone conversion — pick a source city, then add up to four other cities. Set a specific source time, or follow live "now".
- Currency rates — fetched from Frankfurter (ECB-backed, free, no key). Cached for about 30 minutes; the app reuses the cache when you're offline.
- Saved presets — save your most-used time and currency setups and apply them in one tap.
- Offline behavior — the app shell and your settings work offline. Currency rates fall back to the last cached values when you have no connection.
- Reset app data — Settings → Reset app data clears all on-device storage and reloads with defaults.
- TestFlight feedback — if you're on a TestFlight build, you can also use TestFlight's built-in "Send Beta Feedback" sheet, which attaches a screenshot.
Known limitations
- FX rates are informational only and may be delayed. Not for financial decisions.
- v1 is English-only.
- No accounts and no cloud sync — your data stays on your device.
