How would your application know when the user is done editing? I use a "calculate" button in my own app and then call the method end_editing() for all the text fields. That hides the numerical keyboard.

@JonB I'm not sure how strict that is: the Workflow app can write data to HealthKit and that's not primarily a health related app.

I love Pythonista! I would love it even more if it offered support for TextExpander Touch, mainly so I can quickly setup skeleton files with default comments, creation date etc. This would also be useful for quickly setting up a class definition.
