HeyKitsu turns 11+ and ISEB exam prep into an adventure your child will actually want to do. No more nagging. No more battles. Just learning that works. Why parents love HeyKitsu: We know the pressure. You want to give your child the best chance at their target school, but the thought of months of forced revision fills you with dread. HeyKitsu is different. It's the test prep app children ask to use – because it feels like a game, not a chore. What makes HeyKitsu different: - Adaptive learning that meets your child where they are – questions get harder as they improve and revisit areas they find tricky - 100,000+ questions based on real 11+ and ISEB past papers across Maths, English, Verbal Reasoning and Non-verbal Reasoning - Step-by-step explanations for every single question – so your child learns from mistakes, not just repeats them - Friendly animal guides (Ember the cardinal, Kodi the bear and of course, Kitsu the fox) who teach concepts and celebrate progress - A parent dashboard so you can see exactly how your child is doing – without having to ask Full curriculum coverage HeyKitsu covers everything your child needs for 11+ grammar school exams and ISEB Common Pre-Tests: - Maths – from fractions and percentages to algebra and problem-solving - English – grammar, spelling, punctuation, vocabulary and comprehension - Verbal Reasoning – synonyms, antonyms, codes, logic and word patterns - Non-Verbal Reasoning – sequences, matrices, spatial reasoning and more From parents, for parents HeyKitsu was created by parents who've been through the 11+ journey. We know how stressful it can be – and we built the app we wished existed. Download free and see the difference for yourself.

MindStack Flashcards
Read full descriptionHide full description
MindStack helps you remember what you study. Build flashcards by hand, or let the AI do it for you — paste text, drop a PDF, snap a photo of your notes, or just type what you want ("20 cards on the Krebs cycle"). The cards then come back to you using FSRS spaced-repetition scheduling, so you only review what you're about to forget. While studying, tap Hint for a nudge or Explain for a quick breakdown when you get something wrong. Run Audit on any deck and the AI flags duplicates, leaky questions, and cards that need a rewrite. Three card types (Q&A, cloze, term and definition), light and dark themes, streaks with freezes for the busy weeks, a +5 daily boost when you want to push, and a home screen widget showing what's due today. iCloud backup is automatic. Anki .apkg imports in two taps. Works offline once your decks are downloaded. The full study engine is free. AI features (generation, Audit, Hint, Explain) include a 30-day trial, then Pro. Built for students, language learners, and anyone who'd rather remember things than re-learn them next month.
