OmniMathematics

OmniMathematics is a story-driven way to learn discrete math for computer science, and the math around it, on iPhone and iPad. Start with Discrete Foundations: begin with sets, then open one sourced topic at a time. Proof Detective is one of eleven interactives. Neither is a course or a credential. Do — Begin with sets, or pick up the lesson or topic you opened last. Understand — Start here with Discrete Foundations, browse the sourced topics, or take the story tour of 20 chapters in six parts. Ask — Ask a question in your own words. More — Settings and your progress. Sourced topics stay distinct from the story tour. Explanations are compressed; they can omit hypotheses. Ask answers your question with an on-device model and shows what the model writes, labelled as generated; answers can be wrong. Where Apple Intelligence is on and ready, it answers. Otherwise, on devices with 8 GB of memory you can choose to download MiniCPM5 2B (about 1.4 GB); on devices with 12 GB or more, Gemma 4 E2B (about 4.4 GB), or MiniCPM5 2B instead when memory is short, all from Hugging Face. Where no model can answer, including devices with 6 GB or less, Ask shows the matching entry from Concepts, the built-in reference, and the sourced packs. Nothing you type leaves your device. You can turn the downloaded model off, and remove it, in Settings. On Apple Watch, a companion app browses the sourced packs and can send a question to Ask on the paired iPhone. An optional daily study reminder can be turned on in Settings; it is the only permission the app asks for. WHO IT’S FOR • CS and engineering students taking discrete math • Self-learners who want discrete math for CS without the intimidation • Teachers looking for intuition-first explanations • Anyone who loves elegant ideas made human FREE, WITH ONE OPTIONAL UPGRADE The library, all twenty chapters, Concepts and the lab interactives are free, and the whole library ships inside the app. Exporting your progress as a raw file is free. OmniMathematics Pro, from Settings or Progress, unlocks one thing: a formatted study report. Pro is available as a monthly or annual subscription, or as a one-time lifetime purchase. Subscriptions auto-renew until cancelled. Cancel in Settings ▸ your name ▸ Subscriptions at least 24 hours before the period ends. Payment is charged to your Apple Account when you confirm the purchase, or when the free trial ends if you start one. The lifetime purchase does not renew. YOUR DATA No account, no ads, no analytics. Your progress is stored on this device and, if you use iCloud, syncs to your other devices through your own private iCloud database, which Prameya cannot read. Where you left off, your next suggested topic and your appearance choice are also shared with your own devices through iCloud, and Handoff passes along where you left off.
