*You don't need to think about time zones* WhenDo shows your time below. The time of your friends/lovers up top. WhenDo prefers photos over clock icons. Because we’re all beautiful. No more confusing conversations to see when your friends are free. WhenDo makes it easy to share a time, visually. WhenDo works offline so you can check any city, at any time. More of this: • Take a selfie & set your city • Setup your friends • Pick a time that looks good • Share it Less of this: - When do you want to talk? -- Sunday? - Could work. At what time?? -- I’m free at 9. - Do you mean 9:00, my time? -- Haha. Nope. I meant 9 here. - You know that’s 4am for me? -- Oh. :(
