The Whiteboard App always adheres to the concept of "simplicity to the extreme" and "Nothing more Nothing less". Despite offering many small tools, its interface remains simple and user-friendly. This app is suitable for various scenarios, including teaching, creativity, meeting presentations, prototype design, and learning drafts, among others. It provides users with a variety of universally applicable paper formats, objects, and prototype designs to choose from. It also offers instant drawing of geometric shapes, making teaching, creativity, and on-site communication more convenient. Additionally, it can be used for students' homework drafts, doodling, note-taking, temporary notepads, word dictation, and math problems, among other purposes. Users highly praise its simple and easy-to-use button layout and tool exit mechanism. The app offers two forms of creating new files, allowing users to choose the one that suits them best: - The first form is a multi-page file (Pages), where each page serves as a canvas with size limitations, similar to a PDF file. This makes it easy to organize knowledge. - The second form is a free-form file (Free Form), where a file consists of one infinitely large canvas without boundaries. This allows for unlimited creativity. The app also supports direct import of PDF files, even large files with hundreds or thousands of pages, without crashing. It opens instantly.

The lock actually locks. LockIn blocks the apps you choose — and the only way back in is the key YOU picked. Not a toggle you can flip off. A real key: • An NFC tag stuck on your fridge, your desk, your gym locker • A QR code in your wallet (or the barcode on your gym pass) • Your fitness goal — close your rings, hit your steps, earn your apps back • A person you trust who approves early exits • A timer or weekly schedule that holds until it's done • Or plain one-tap blocking when you just need a nudge Every focus session builds something: your Realm — an island that grows piece by piece with every session you finish. Miss a day and it weathers. Keep showing up and it becomes somewhere you don't want to burn down. WHY IT WORKS LockIn is a commitment device. The friction is the feature: when quitting means walking to the fridge to scan a tag, you mostly don't quit. • Smart Breaks — pause for a few minutes without ending the session; blocking resumes automatically, even if you force-quit the app • Strict Mode — apps stay blocked even if you try to delete LockIn • 3 emergency unlocks per month. Genuine emergencies only. That's the point. • Weekly schedules that arm themselves — even when the app is closed • Live Activity on your Lock Screen and Dynamic Island • Siri & Shortcuts: "Start LockIn" from your Action Button PRIVATE BY DESIGN Your app selections, health data, and location never leave your iPhone. No accounts. No analytics. No ads. (Full policy inside the app.) Lock in. Build your realm.
