Works well, responsive developer The app does what I expect, and the developer was responsive to questions.
Pretty good It's missing a few essential features: copy and move checklists.
The Android version of this app crashes when the screen is rotated. QRouting's help desk told me that it was a known bug and would be fixed shortly in the next release. That was 4 weeks ago and still nothing. I notice that the current version (ver 2.02) was released in September 2014. If bug fixes haven't been released in a 15 month time frame, I'd guess you'd have to class this as "mature" software that isn't supported.
Fixed bug, not rotating screen in some devices
