Multi device presentation time

Free · Designed for iPad. Not verified for macOS.

Use it for conferences, seminars, lectures, IR pitches — anything where time management is the job. ■ Use cases • 30-minute IR pitch: Apple Watch on the wrist, iPad next to the presenter as a large-clock backup • 1-hour lecture: Mac laptop at the operator's desk, iPhone in the presenter's hand as backup • Multi-track conference: an iPad + Apple Watch per track keeps every presenter on time ■ Design philosophy "Whatever the device, wherever the presenter, the time is in their hand." ※ The Mac desktop app is a separate download — get it from apps.onoffmix.com.
