Silent Presentation Timer is the most unobtrusive presentation timer, lecture timer, or meeting timer ever. Just keep the phone in your pocket and feel the silent vibrations. I use the timer during my own meetings, presentations, and lectures and I have been developing it using my own presentation experience. The application is available for phone as well as in a version for Wear OS, fully connected and integrated with the phone app. And all this is for free, without ads. Features: - full Wear OS/smartwatch support, application runs on phone as well as on Wear - ambient low power mode support with special presentation visualization on the Wear device - configurable length of presentation/end time of presentation - countdown presentation timer with visualisation - green (lots of time left), orange (lots of time passed), red (close to end) indication of the time left for your presentation - optional measurement of overdue time (violet) - presentation timer can run in background - runs if you put the phone to the sleep mode - set the timer, run, and put your phone sleeping to your pocket - runs even if you switch to another application and the intervals will be still indicated by vibrations - change of phone orientation or incoming call will not stop the presentation timer - optional screen dimming (to save battery if you disable sleep) - optional disable of the phone sleep mode User\s guide: http://papacut.sweb.cz/dt_wear_users_guide_international.html Have fun and enjoy your presentations!
