A timer that talks you through time. Built for the brains that lose track of it. For brains that lose time, a countdown that speaks so you do not have to look. Most timers are silent rectangles. For an ADHD brain that experiences time-blindness, that is the same as not having a timer at all. Time Blind Timer talks to you. It speaks check-ins at the pace you choose, in your own iPhone voice, while the screen stays dark and the world keeps going. Why people stay: - Audio first. Every cue is spoken aloud, not a tiny number on a screen you have to unlock. - Locked screen friendly. Confirmed background-audio behavior. Designed to work while you are doing literally anything else. - Your voice. Pick any iOS voice (Samantha, Daniel, Karen, Moira, and the high-quality Enhanced voices) with rate and pitch tuned per persona. - Your cadence. Adjustable announcement frequency from every 30 seconds to every 15 minutes, plus a Natural countdown that mirrors how humans warn each other (10m, 5m, 2m, 1m, 30s, 10s). - Elapsed-time mode. Optional toggle to announce 'You are 18 minutes in, 7 left' instead of only 'remaining'. The time-blindness receptor responds better to elapsed than to remaining alone. - Routines, not just timers. Start a morning anchor, a bedtime wind-down, a Pomodoro block, a study session, a leave-the-house countdown, or build your own. Each step has its own spoken cue. - No shame. No streaks. No 'you failed' copy. No gamification guilt. Just a calm narrator that keeps you company. - Real-time interruption handling. The clock keeps running through Siri, phone calls, YouTube. The next scheduled cue plays fresh, never an awkward stale announcement. - Local first. No account. No cloud sync. No tracking. No analytics. Your timer state lives on your phone only. Built for ADHD by people who have it, with line-editing input from an ADHD-PCC therapist. Made by Nice Notions LLC.

Calenduhh is a planner for people with real lives. Five quick questions, and every shift, commute, routine, and night of sleep is already on the page — through next year. YOUR DAY, HONESTLY Free time shows up as free time, labeled in hours, honest about commutes. Hold any block and drag it — sleep bends around your plans, work and routines hold firm until you say otherwise. LISTS THAT BEHAVE Quick notes land in an Inbox. Unfinished to-dos roll forward on their own — and after three rolls, we ask if it still matters instead of nagging. A PLANNER THAT FORGIVES A weekly check-in eases the app off when you're running on fumes: suggestions pause, free time stays protected, reminders go quiet until you feel better. LIFE ADMIN, INCLUDED Birthdays remembered every year with the math done. Car maintenance and upkeep meters. A grocery list that suggests one grocery run, not ten errands. Optional, private cycle tracking right on your calendar. Say it out loud — "add Dad's birthday June 5th" — and it lands where it belongs. SHARE WITHOUT THE APP Send your week, month, or the chore list as a clean image. The people you share with don't need Calenduhh. FREE FOREVER The whole planner is free — no time limits, no locked basics. Calenduhh Plus adds widgets, iCloud backup & sync, Apple & Google calendar import, voice capture, the day & cycle journal, and unlimited meters. PRIVATE BY DESIGN No accounts, no ads, no tracking. Your plans live on your device and, with Plus, in your own private iCloud — we can't see any of it. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
