Soundless Timer is designed to use vibration only, so you can keep your phone in your pocket or on your lap and be the only one who notices when time is up. Simple by design •Menus and screen transitions are kept to a minimum so you can set a time and start the timer immediately. •Ads are placed so that they do not get in the way of operating the timer. Notes •If you want the timer to run in the background, make sure notifications are enabled for the app. •Vibration strength and patterns depend on your device settings. •Depending on settings such as Silent Mode or Do Not Disturb, vibration may not occur. Please check operation in advance before using the app in important situations.
