Write down the idea, say how much it matters, and Lectrum brings it back on its own schedule. No account, no subscription, nothing to unlock. 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 Open the sheet, type the thought, pick Low, Medium or High. That is the whole flow. Any idea can have its reminders switched off and still be kept. RESURFACING • High and Medium ideas arrive as reminders on your phone • You choose the frequency for each level, from every hour to once a week • Low ideas never notify — they appear in a Resurfaced section instead, and Keep defers them one more round • Set an exact time of day for reminders, per level • Quiet hours hold anything that would land overnight until the morning FROM THE REMINDER Complete an idea without opening the app, or snooze it to later today, tomorrow, the weekend, next week, or a date you pick. Tap the reminder itself and you land on the idea. ON THE HOME SCREEN The Up Next widget shows what is coming back to you, on the Home Screen or the Lock Screen, so an idea can reach you without opening anything. A DATE OF YOUR OWN Any single idea can also carry a one-off reminder on a date you choose — including a Low one that would otherwise never notify. THE LIST Grouped by importance, newest first, with each idea's next reminder shown on its row. Search it, or filter it down to one importance level. Swipe right to complete, left to archive or delete. Completed and archived ideas keep their own shelves in the Library — nothing disappears unless you delete it. ACROSS YOUR DEVICES Your ideas sync privately through your own iCloud account. WHAT LECTRUM DOES NOT DO There is no account to create. No subscription, no purchases, nothing to unlock. No ads. No analytics and no tracking — no data about you is collected at all. Your ideas live on your device and in your own iCloud. Reminders follow your phone's clock, so exact times and quiet hours stay correct when you travel or the clocks change.
