Tally 1.1 adds x-callback-url support to our quick-counting app for iPhone. Tally supports two actions, “increment” and “decrement” – with full support of callbacks. This allows Tally to be included in automation workflows with Drafts and other apps – should you feel like you need to keep track of how many times you executed a workflow or similar.
I’ve never had a use for Tally, but this update looks interesting. If, for instance, you were to use a Draft 3.0 action to append text to an Evernote journal, you could integrate Tally to count the times the action is fired every day – perhaps by triggering everything from a Launch Center Pro timed notification.
If you’re looking for more examples, Eric Pramono has some good ones.
