The most recent update was last week. The previous update is over 3 years old. They seriously have given up development of this app. No bt support, no scaling improvement for 6 plus. Honestly, let me take over development. I sent you all an email so I could perhaps help you out since you cant work on your own app, but no one got back to me. Incomplete.
