Spaced Math helps kids master addition, subtraction, multiplication, and division facts with short daily practice. Instead of random drills, it uses spaced repetition to bring each fact back right when it's ready to review — so practice stays short and focused on what your child actually needs. FREE TO TRY Start free with one child profile and one operation of your choice — the complete spaced-repetition experience, with voice, handwriting, iCloud backup, and progress all included. One simple unlock adds everything else, and it's shared with your whole family. No subscriptions, no ads, no accounts. MATH FACTS THAT STICK Every child gets a personal review queue. New facts, weak facts, recent mistakes, and overdue facts are tracked separately, so sessions stay short and useful. Choose any operation and control the active numbers from 1–12. THREE ANSWER MODES Kids can answer the same fact three ways: • Keypad — fast, simple, reliable. • Voice — speak the answer naturally ("twenty-four", "two four", or "144"). • Handwriting — write with Apple Pencil or a finger. Switch modes anytime. Voice uses Apple's speech recognition; we never see or store the audio. BUILT FOR FAMILIES Create up to 8 profiles on one device. Each profile keeps its own progress, settings, streak, mistakes, and review schedule. Parent-locked settings keep kids practicing the facts you picked. THREE SESSION TYPES • Study — spaced-repetition review for the facts due today. • Practice — free drill, biased toward weak facts by default. • Review — focused cleanup for mistakes, lapsed facts, and overdue cards. READABLE PROGRESS See due and new counts, learned facts by operation, streaks, and mistakes. Parents can tell what's improving and what still needs work — without managing a classroom system. OPTIONAL ICLOUD SYNC AND HOUSEHOLDS Use Spaced Math on one device, or turn on iCloud sync to keep progress in step across your devices. Set up a household to share every child's profile with family members. Manual JSON export/import is available for backup. Sync uses Apple's CloudKit — your data goes to your private iCloud, never to us. PRIVATE BY DESIGN • No ads, no subscriptions, no accounts. • One simple one-time unlock — that's the only purchase, and it's Family-Shared. • No analytics, no third-party SDKs, no developer-operated servers. • Microphone audio is processed live and discarded. We never see it. • Deleting a profile actually wipes it — including the iCloud copy on the originating account. iPhone and iPad. iOS 15.0 or later.
