Action Button Pro lets you supercharge the Action Button on your iPhone. Create conditions and assign actions to them. Some examples: - If I'm playing music, open Spotify - If I'm on the train, open the Podcasts app - If I'm at work, open Slack - If a meeting just started, start a new note - If it's after 10pm, turn on the flashlight - If the Warriors or the Bulls are playing, open ESPN Sequences. Group your triggers into sets like Work, Travel, or Gym and switch between them from the top of the screen. Give a sequence its own condition and it switches itself when you get there. Not sure where to start? Six templates get you running in a tap. And when you press the button, you can see exactly which conditions passed, which didn't, and why — plus a history of everything your button has done. So many unique combinations and we are listening to feedback for any other suggestions you may have! Send feedback to me@shabz.co Works on any iPhone with an Action Button — iPhone 15 Pro and later.
