Intervalometer – interval camera shutter for time lapses

Hi,

there is a great Android app called “Intervalometer“ that lets you choose a time interval and then simulates a physical button press. This works in every camera app because it is a floating app overlay. This makes the app very versatile and great for manual photo time lapses.

Here a video of that app (minute 1:48): https://youtu.be/q6ds6KJYdns?t=108

Does somebody know an alternative for iOS? An app or some kind of advanced bluetooth/wired remote shutter?

Thanks!
