Sagito is an 11+ practice application focused on mathematics, English, verbal reasoning, and non-verbal reasoning. It contains a total of 5,000 questions, with 2,000 available for free with no daily usage cap and no account registration required. The app is designed to operate entirely on the user's device, with no data collection, advertising, or analytics transmitted externally. It includes an adaptive difficulty system that assesses a child's starting level from their first answers and adjusts question difficulty in real time, providing warm-up questions for those who find material challenging and more advanced questions for those who excel. There are no daily limits, energy meters, or countdown timers, and the app does not interrupt practice sessions with purchase requests. The app features a gamified reward system where answered questions advance an expedition. Children earn original illustrations of British wildlife as collectible cards and coins that can be used to customize a virtual camp. All cards and camp items are earned exclusively through practice and cannot be purchased. The app supports social interaction through a controlled card and item swapping system between friends and family, where requests can be declined. Each child using the app can have a personal progress profile protected by a PIN, preventing siblings from answering for one another. A parent PIN-protected area provides detailed progress reports by subject and topic, identifies areas needing improvement, and tracks practice volume. Optional purchases, including extra camps and a subscription for the full question bank, are located only behind this parent PIN. Typical use cases involve daily independent practice sessions for children preparing for 11+ exams. The app includes a "School focus" feature that provides question sets styled after specific schools, including Queen Elizabeth's (Barnet), St Olave's, Wilson's, Henrietta Barnett, and Tiffin Girls', with all questions in this mode set at Stretch level or harder. A companion character offers encouragement, jokes, and facts throughout practice. The app is designed for shared family use, allowing multiple children to maintain separate progress, card collections, and camps on the same device. Technically, the app requires no user account, sign-in, or internet connection for its core functionality. The only network communication occurs during optional purchases processed through Apple or Google, and no child data is transmitted during these transactions. Purchases are handled exclusively through in-app payment systems and are stored behind the parent PIN. The free tier provides approximately six months of daily practice before any purchase consideration, and earned progress and items are retained if a subscription ends.
