Review trajectory.
Daily review count and rating drift. The blue line is cumulative review count; the dashed amber overlay is the rating on the right axis. Boring is good — sudden swings stand out against an otherwise stable curve.

“I only just started using the app but have found it to be easy to get into, the feature set is robust, and it's simple and easy to use. The developer gave a few different price tier options that are fair and balanced, and I don't feel like I'm either lacking a feature or need to upgrade for one thing. It's a well built app and so far is working great!”
