Hi there -
If you'd like us to integrate Walkdroid into the app, that may be possible, but you'll need to reach out to them. We suggest this message:
"I'd love for Walkdroid to be integrated into MedHelp's My Diet Diary app. Their API will soon be available publicly."
Currently, we have FitBit One integrated, and it has a step counter in it, along with some other cool things. We also have FitBit Zip and FitBit Ultra, but the Ultra isn't being made any longer.

We probably won't be able to add our own pedometer, but I hope this helps. Let us know if you have any questions.
Emily
