Blitz vs Orbit

Blitz is the fast, private way to memorize anything — languages, geography, code, music theory, medicine, or your own material. One small payment, yours forever. No subscription, no ads, no account. SMART SCHEDULING Rate each card Again, Good, or Easy and Blitz schedules its return for the moment you'd otherwise forget it. Hard cards come back sooner, easy ones fade into the future.

Orbit is a spaced-repetition flashcard app built around one idea: memories are satellites, and reviewing them is what keeps them from losing altitude. THE ENGINE Orbit is scheduled by FSRS (Free Spaced Repetition Scheduler) — the same open-source algorithm that's become the standard among serious Anki users because it predicts your memory more accurately than older SM-2-style algorithms. Fewer wasted reviews, fewer forgotten cards. WHAT YOU GET • Anki-style notes and cards, including cloze deletion and rich text (bold, italic, code, fenced blocks) • Image occlusion — turn any photo, diagram, or map into a set of flashcards by drawing masks directly over the parts you want to test yourself on • A full stats suite: retention over time, forecasted review load, a knowledge heatmap, leech detection for cards you keep forgetting, and deadline readiness for exams or deadlines • Streaks, XP, and banked streak freezes that reward consistency without shaming you for a missed day • Text-to-speech playback for hands-free review • A free starter deck — Flags of the World, 197 cards — so there's something worth reviewing the moment you install PRIVATE BY DEFAULT Orbit makes no network calls for your data. Everything — every card, every review, every stat — lives in a local database on your device. Nothing is uploaded, nothing is sold, there are no ads, and there's no account to create. Delete anything, anytime. BUILT FOR DAILY USE Grading a card is a single tap with haptic feedback. The next card is pre-rendered before you finish grading the current one, so review sessions stay fast even for long backlogs. Dark mode is a first-class experience, not an afterthought. Whether you're relearning a language, studying for boards, or just trying to remember more of what you read, Orbit is built to keep it in orbit.
