Platzwahl creates seating plans for your class. Draw your classroom as a grid and add your class, by hand or via CSV import. For each student, note how disruptive they are, whether they should sit at the front, and who they should or shouldn't sit next to. With Platzwahl Pro, the app turns this into a seating plan with one tap: disruptive students go to the edges and are kept apart, and preferences are respected where possible. A score shows how good the plan is and lists every violation. You can move students by drag and drop at any time. Free: one room, one class and one seating plan, with students placed by hand. Platzwahl Pro: unlimited rooms, classes and plans, automatic calculation, PDF export, printing and iCloud sync between iPad and iPhone. Student data stays on your device. Only if you turn on iCloud Sync is it stored in your private iCloud, with student names and traits end-to-end encrypted.

Your apps are locked. One right answer opens them. > The problem: a phone wins every idle moment. Scrolling quietly eats whole evenings, and every "just five minutes" costs you the focus you had. > The fix: Emberlock flips the trade. Your most distracting apps (Instagram, TikTok, games, whatever pulls you in) stay locked until you earn them. Answer flashcards on a subject YOU choose, or put the phone down and knock out a set of reps. Learn first. Scroll after. WHAT CHANGES • Opening an app becomes a decision, not a reflex: a 6-second gate beats endless willpower. • Every doomscroll urge becomes a rep for your brain: real questions, real subjects, real recall. • Your streak compounds. Keep the ember lit day after day and watch the answered-questions count stack up. • When the timer runs out, the apps lock again. The trade is always the same, and it is always in your favor. HOW IT WORKS 1. Pick the apps to block and how you want to earn them back. 2. Open a blocked app → a challenge appears instead. 3. Answer correctly, or finish your set → your apps open for 15 to 120 minutes. You choose. 4. Keep the streak alive. Milestones, streak shields, and a shareable Study Wall card mark the run. THREE WAYS TO EARN THE UNLOCK • Study: flashcards on a subject you pick. 18 ready-made subjects built in: SAT vocab, biology, chemistry, Spanish basics, coding, history, psychology, law, medicine, and more, plus fact sets for world capitals, currencies and elements. 3,600+ curated questions that work fully offline. Or your own deck: type or paste questions and answers, or import a CSV, and the next unlock asks them. • Move: your phone counts reps with its motion sensors: push-ups, squats, jumping jacks. You choose how many it takes. • Wait: a short cool-down you set. No quiz, no reps, just a pause the urge rarely survives. PERFECT FOR • Students who reach for TikTok instead of their notes • Anyone with ADHD whose phone wins every fight for attention • Professionals who lose evenings to the feed • Language learners and exam preppers who want stolen minutes back • Anyone who has tried deleting apps, and just reinstalled them THE HONEST DEAL • Free tier that stays free: five unlocks a day, every mode, every subject, resetting at midnight. • Pay once and keep it forever. One price, no subscription. • Pro adds unlimited decks of your own (one is free), 8 fact decks in Learn, and no daily cap. • On iPhones with Apple Intelligence, build a course from your notes, PDFs or links on the device itself; one is free, Pro adds unlimited. • Private by design: no account, no ads, no tracking. Your decks and notes stay on your phone. Nothing is uploaded or shared. • You are always in control: Emberlock uses Apple's Screen Time (Family Controls) so YOU choose what to block, and you can change it any time. THE SCIENCE Retrieval practice, recalling an answer instead of re-reading it, is one of the most consistently supported findings in learning research. Emberlock turns the moment you most want to waste into the moment you remember something. That is the whole trick: the habit you can't quit starts paying for the one you can't start.
