Shout Clock
Read full descriptionHide full description
The stopwatch and countdown you control with your voice, for training with your hands full. Say “Shout, go” and it starts. “Shout, lap” marks a lap. “Shout, how long” and it tells you. No touching your phone, not even looking at it: Shout Clock answers out loud, in your headphones or on the speaker, while your music keeps playing. Two switches, two directions: • Shout talks to you: it calls out the time, how long is left, the final seconds • Talk to Shout: you give the commands, Shout listens COUNTDOWN • Pick a duration with one tap: 30 seconds, 1, 2, 3 or 5 minutes, or any length you like • It tells you how long is left, as often as you choose: “thirty seconds left”, “one minute left” • It counts the last 5 or 10 seconds out loud: “five, four, three, two, one” • At zero it says “Time!”. Say “Shout, go” and it starts again for the next set STOPWATCH • “Shout, lap” marks a lap and tells you its time • If you want, it calls out the elapsed time every 30 seconds, every minute or every 5 minutes • Pause, resume, reset: by voice or with the big buttons BUILT FOR TRAINING • Works with the screen locked, phone in your pocket or your bag • Your music doesn’t stop: the app’s voice plays over it • Answers right away, no Siri in between • Big buttons and digits you can read from across the room YOUR AUDIO STAYS YOURS Speech recognition happens entirely on your iPhone. Neither audio nor transcripts leave your phone, and nothing is recorded or stored. No account, no subscription, no ads. WHAT YOU CAN SAY “Shout, go” · “Shout, pause” · “Shout, resume” · “Shout, lap” · “Shout, reset” · “Shout, how long” · “Shout, quiet” · “Shout, talk” ENGLISH AND ITALIAN Shout Clock understands and speaks English and Italian. It follows your iPhone’s language, or you can pick one in Settings: screen, commands and voice switch together. Requires iOS 26.
