Tinny(not) quietly marks the hours so you don't have to check your phone. It is built for people who lose track of time. For anyone with ADHD who needs gentle cues rather than overwhelm. For deep work and Pomodoro. For meditation. And for anyone who simply wants to know that another hour has passed. Pick your hours, pick your sound, forget about it. Tinny(not) chimes on schedule (on the hour, every 30 minutes, or every 15) using iOS notifications, so it keeps working even when the app is closed. SET IT ONCE, RUNS FOR YEARS No accounts, no login, no syncing. Choose your hours and days, turn chime on, and Tinny(not) handles the rest in the background. A DIFFERENT SOUND FOR EVERY QUARTER HOUR Not just one chime: assign a distinct sound to :00, :15, :30, and :45 independently. Know which quarter of the hour it is without looking. WHAT EACH SOUND IS CALLED Every chime has both a name and a plain description, so you know what you are picking before you pick it. Free, for as long as you use the app: Chalet (cuckoo clock), Dot (beeper), Kyoto (buddha bowl), Linden (wind chimes), Parlour (call bell). Included in the one-time purchase: Belfry (striking clock, Westminster and Big Ben style), Courant, Dorje (Tibetan bell), Helm (ship's bell), Meridian (time signal pips), Ohm (singing bowl), Pendulum (grandfather clock, Westminster and Big Ben style), Quai (public announcement), Vesper (bell), and the Speaking Clock. SPEAKING CLOCK Have the time spoken aloud instead of chimed. Pick any voice installed on your device: Tinny(not) reads out the hour and minute in your voice of choice, using your phone's own language and time format. BRING YOUR OWN SOUNDS Import your own recordings (.wav, .caf, .aiff, up to 30 seconds) and use them as chimes alongside the built-in collection. YOUR OWN NOTIFICATION TEXT By default a notification simply tells you the time. You can replace it with your own words and give each mark (:00, :15, :30, :45) its own text, a reminder to stretch at :30 or to wrap up at :45. With the Speaking Clock, Tinny(not) reads your text aloud instead of the time. SOUND ONLY, NO CLUTTER If you would rather hear the chime with nothing on screen, Tinny(not) tells you which three switches to turn off (Banners, Lock Screen and Notification Center) and opens the right Settings page for you. After that it plays its sound with no visual interruption at all. SCHEDULE YOUR WAY Use the presets for work hours, waking hours or all day, or tap Custom and pick exactly the hours you want. Days work the same way: every day, weekdays, weekends, or any combination of days you choose. FREE, WITH OPTIONAL EXTRAS Tinny(not) is free to use, with no time limit and no ads: hourly chimes for any hours you choose, every day, with five sounds. If you want more, one optional purchase gets you every sound, custom imports, the speaking clock, sub-hourly intervals, weekday, weekend and custom day schedules, and your own notification text. No subscription, and it's yours for good. PRIVATE BY DESIGN No accounts, no analytics, no tracking. Tinny(not) doesn't know anything about you it doesn't need to.
