About

FocusCard

Read full description

You sit down to do one thing — twenty minutes later you're three apps deep wondering why. FocusCard puts that one task, huge, on your screen and Lock Screen, until you mark it done. You'll still drift. The way back is one tap. Built for deep work, ADHD focus, and anyone who's ever taped a sticky note to their laptop. HOW IT WORKS • Pick one task from your iOS Reminders. • Tap it. The screen turns black, the title fills it. • The same task lives on your Lock Screen and Dynamic Island while you work. • Tap "Mark Complete" when done. Tap anywhere else to pause. FEATURES • Reads from iOS Reminders. No extra task list to maintain. • Grouped by Reminders list, color-coded. • Lock Screen Live Activity with the active task title. • Screen stays awake during focus sessions, so you can prop your phone up. • Swipe left or long-press to mark done, with undo. • Settings lets you choose which Reminders lists show up. • Long-press any reminder to deep-link to it in the Reminders app. WHY THIS WORKS FocusCard isn't a Pomodoro timer or a habit tracker. It's a digital index card, propped where the thing you most want to ignore lives. The research: • Attention residue (Leroy, 2009): switching tasks leaves cognitive sludge. A single visible focus reduces it. • The Zeigarnik effect: unfinished tasks loop in your mind until you externalize them. • Cognitive offloading (Risko & Gilbert, 2016): writing a task down frees working memory. PRIVACY FocusCard does not collect any data. No accounts. No analytics. No third parties. The whole app runs on your device. BUILT BY ONE PERSON For a year I had a stack of 3×5 index cards on my desk. Every morning I'd write the one thing I most needed to do, in big letters, and prop it next to my laptop. The cards worked. They kept going missing. So I built FocusCard. Same idea, on the device I always have with me. — Dewang Mistry

About

Byosoku Memo

Features
Read full description

Between “open” and “write,” there is nothing. Byosoku Memo is a zero-friction notepad: the moment it launches, a new note and the keyboard are already there. No hunting for buttons, no flipping pages — the app finally keeps up with “let me jot this down before I forget.” ■ Open = start typing Tap the icon and a blank note with the keyboard appears at once. No splash screen, no confirmation dialog. ■ Auto-save, always There is no save button. Every keystroke is saved instantly. Close an empty note and nothing is left behind — no junk notes. ■ Lock Screen & Home Screen widgets Jump straight from a Lock Screen widget into a new note. The Home Screen widget lists your recent notes; tap one to open it directly. ■ Control Center (iOS 18) Add “New Note” to Control Center and start writing from anywhere with one tap. ■ Smart full-text search Kana, full/half-width and upper/lowercase are all treated alike, with multi-word AND search to find any note fast. ■ Export & share Share a single note, or export your whole list as a text file. All data is stored on your device. No account required. [Pricing] Every feature is available. A banner ad is shown at the bottom of the screen. A one-time “Remove Ads” purchase hides it permanently (no subscription). Privacy policy: https://honki.ai/byosoku-memo/privacy.html
