About

ScrollWager

This app locks your applications, requiring you to earn screen time by completing challenges or physical activities to unlock them. It aims to make app usage a conscious decision rather than an automatic habit. Earned minutes carry over, and a hard daily limit prevents excessive challenges.

Highlights
  • Apps locked around the clock
  • Unlock one app at a time
  • Earn minutes by moving
  • Hard daily challenge limit
  • Strict Mode for deletion prevention
  • Streak and milestone tracking
  • Usage history

Your apps are locked. All day, every day. To get in, you spend screentime you earned. Tap a locked app and ScrollWager asks one question: how much of your screentime is this worth? Set the amount, take the challenge, live with the result. Win and the app opens for exactly the minutes you set. Lose and it stays locked. That is the whole idea. Scrolling stops being automatic and becomes a decision. HOW IT WORKS 1. Pick the apps you want locked. They stay locked around the clock — no schedules, no time windows, nothing that opens on its own. 2. Tap one. ScrollWager asks how many minutes it is worth to you, starting at 5. 3. Take on the challenge. Flip a coin, spin a wheel, play a hand, clear a grid or drop a ball. 4. Win and the app opens for the minutes you chose. Lose and those minutes are gone. 5. Out of minutes? Earn more. Walk, do pushups in front of the camera, or solve a quick puzzle. WHAT YOU GET - Locked around the clock. No schedule to set, no window that opens by itself. - One app at a time. An unlock opens the app you tapped, not your whole phone. - A daily allowance. Each morning your balance is topped up to the daily limit you chose. Minutes you earn on top stay until you spend them. - Earn by moving. Steps and camera-counted pushups both pay into your balance. - Earn by thinking. A daily Word Guess, Word Groups, Logic Grid and Sudoku, plus Quick Math and Trivia anytime. - Strict Mode. While it is on, no app can be deleted, ScrollWager included, and locked apps cannot be taken off your list. Adding more is always allowed. - Streaks and milestones. Every day the lock holds counts. - History. What you earned, what you spent, and what it cost you. BUILT FOR - Anyone who opens the same app without deciding to - People who have tried blockers and tapped straight through them - Students and anyone protecting a block of work - Anyone who wants scrolling to cost something instead of being forbidden PRIVACY ScrollWager uses Apple's Screen Time API. Which apps you pick and how you use them stays on your device — Apple's system does not let that data out. SUBSCRIPTION ScrollWager needs an active subscription to lock and unlock apps. Without one the locks come off, and your app list, balance and streak stay where they are.

Lectrum is for the ideas you have once and never think about again. Write the thought down, mark how much it matters, and Lectrum brings it back to you on its own schedule. High-importance ideas return often. Medium ones return less often. Low ones never interrupt you at all — they wait at the top of your list until their time comes. CAPTURE ANYWHERE Tap +, or tap the waveform and just talk: "call the dentist tomorrow at nine" is saved with its reminder already set, and two ideas in one breath become two. Or ask Siri — "Talk to Lectrum". Share a link or a passage from Safari, Mail or Notes straight into Lectrum. Add a Control Center button and capture without opening the app. Attach a photo. Write in Markdown if you like — headings, lists, links and checkboxes all render. RESURFACING • High and Medium ideas arrive as reminders; Low ideas appear in a Resurfaced section instead • One optional daily digest gathers everything due today • Ideas you keep letting pass ease off by themselves; open or edit one and it steps back up • Set an exact delivery time per level, and quiet hours for the night • A one-off reminder on a date of your choosing, for any idea AT THE NEXT MEETING Turn on Meetings and Lectrum remembers which calendar event an idea was written in, then brings it back when you next meet the same people. Your calendar is read on this device only. ON YOUR WRIST AND YOUR HOME SCREEN On Apple Watch, raise your wrist and capture an idea by voice, scribble or typing; it lands on your iPhone understood like Talk, reminder and all, and a complication opens Lectrum ready to listen. Up Next and single-idea widgets sit on the Home Screen and Lock Screen, and they are interactive. PRIVATE BY DESIGN Lock the app with Face ID or a passcode, with auto-lock, and hide idea text from widgets and search while locked. There is no account to create, nothing to buy, no ads, and no analytics or tracking. Your ideas live on your device and sync through your own iCloud; you can also mirror them to a Markdown folder in iCloud Drive you control. Reminders follow your phone's clock, so exact times and quiet hours stay correct when you travel or the clocks change.
