@steve I should note that adding IFTTT tags in the Android app is a bit of a hit-and-miss affair, because the screen doesn't update properly. But if you enter a tag, press save, leave the screen and go back to it, you should find it there.

The way I did it was:

1. In the Flic app, under Providers (top right menu), choose IFTTT
2. Add tag names for as many different IFTTT recipes as you need
3. In IFTTT, create a new applet with Flic as the trigger.
4. Choose "A Flic with a tag is clicked". You can select from your tags in the list, and create the rest of the recipe.
5. Back in the Flic app, assign IFTTT as an action, and select the tag for your IFTTT applet.

That should be it!
