What's New in Flippi
1.0.3
July 26, 2026
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.
