Most notes apps give you a list. Lists are where things go to be forgotten. CustosNotes keeps the note where you cannot miss it: the top of your screen. Hold the circle, say the thing, let go. Then tap once and that note stays pinned — in the Dynamic Island, on your Lock Screen, in your status bar — until you decide it is done. HOW IT WORKS • Hold the circle and speak. One button, no menus, no cursor to find. • Your phone's own recogniser writes it down, in your language. • Let go and the note lands. It starts switched off; you choose which ones earn a spot up top. WHERE IT STAYS • Dynamic Island — the mark and the time, beside the camera (iPhone 14 Pro and later). • Lock Screen — the whole note, readable without unlocking. • Live Activities & Status Bar — pinned notifications and status updates that stay visible until you dismiss them. REMINDERS, WITHOUT THE CEREMONY Tap the clock, spin the dial, done. It saves as you turn. No date to pick — a time that has already passed means tomorrow — and nothing to confirm. ALSO • Type instead of speaking, for when you cannot talk. • English and Spanish, app and mic together. • Dark mode that follows your phone. • No account, no sign-up, no server. Your notes live on your phone. CustosNotes does one thing. It makes sure you do not forget it and your data does not get out of your device.

One round, one thing. Roundi holds you to a single task and shows the time as color: focus you can see. Turn the dial, press start, and a disc of color begins to disappear — like a kitchen timer for your attention. No numbers counting down, no notifications pulling you back. Just time, visibly running out. THE ONE RULE Leave the app — or lock the screen — before the round ends, and the round is lost, instantly. That's the whole trick: Roundi doesn't block anything, it just makes leaving cost something. (Too strict? There's a Lenient mode.) MADE FOR YOUR RITUALS • Meditate — 15 quiet minutes, watching the color fade • Study — a 50-minute block with no pings • Work — deep work sessions up to 2 hours • Train — planks, dead hangs, rest between sets Save each ritual as a tag and it becomes a one-tap start button with its own duration. SAY IT, DON'T TAP IT "Start Plank in Roundi." Between rounds, Siri sets the length, starts a tag, adds another round, or tells you your streak. Hands free — and once a round starts, nothing interrupts you. ON YOUR WRIST Roundi runs on Apple Watch too. Turn the Digital Crown, tap START, and the color sweeps away on your wrist; a tap and a chime mark the end. Watch rounds land in your iPhone's calendar, Siri works on the watch, and one rule carries over: unlock your iPhone during a watch round and the round ends. A TIMER YOU'LL WANT TO LOOK AT Choose how time drains: a clockwise disc, a color that falls or rises across the whole screen, or a spiral coil that unwinds from the outside in. Six soft colors. A chime and a soft blink of color when the round completes. EVERY ROUND, KEPT Finished rounds land as dots on your calendar, with your daily total and streak. Time becomes habit; habit becomes you. PRIVATE BY DESIGN No account. No sign-up. Your rounds stay on your device. Set a time. Stay focused. One round at a time.
