This indicates recent development and ongoing support. ## Version history (last 4 releases) ### 1.0.3 — 2026-07-26 Reliability and accessibility improvements throughout. • Fixed a scheduling bug where a card could get stuck as permanently due if you had customized your review timings. • Review, practice, and add cards while offline. Flippi falls back to your saved settings and tells you when it can't reach the network. • Decks and due counts load faster and use much less data. • Higher contrast on the rating buttons and throughout the app, in both light and dark themes. • Improved VoiceOver support: the card, the rating buttons, and the stats chart can all be read aloud. • Long answers now scroll instead of being cut off, including at large text sizes. • Editing a card no longer discards what you typed while it was still loading. • Reviewing on one device no longer overwrites edits made on another. • Added Privacy Policy and Support links in Settings. ### 1.0.2 — 2026-06-27 • Card audio: hear any card read aloud with text-to-speech, and set a separate language for each side — great for language decks. Turn on auto-play in Settings to hear cards automatically during review. • Study in both directions: set each deck to Front → Back, Back → Front, or a shuffled mix. • Dark mode: choose System, Light, or Dark under Settings. • Faster card creation: add cards back-to-back without reopening the editor. • Safer account deletion: type "delete" to confirm, so it can't happen by accident. ### 1.0.1 — 2026-06-25 • New: Customize your review timing — tune the Again / Hard / Good / Easy intervals under Settings to fit how you study. • Fixed: the keyboard no longer blocks the title/description fields when adding a new deck. ### 1.0 — 2026-06-24 No release notes. ## More apps by PIRAEUS TECHNOLOGY LLC - [ConjuGo ES](https://appshunter.io/ios/app/conjugo-es/id6759270074) - [VocabGo ES](https://appshunter.io/ios/app/vocabgo-es/id6767120915) - [ConjuGo JP](https://appshunter.io/ios/app/conjugo-jp/id6781443990) - [VocabGo JP](https://appshunter.io/ios/app/vocabgo-jp/id6786580278) - [KeiGo JP](https://appshunter.io/ios/app/keigo-jp/id6787575609) All apps by PIRAEUS TECHNOLOGY LLC: https://appshunter.io/developer/1877773120 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
