Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.
Visual and usability improvements to make the app easier to use. If you run into any issue or have a suggestion, feel free to contact me at [email protected] or directly from the app; I'm the sole developer of this project and your feedback is very important to me.
Appworthy
calca-appWhat the stores publish. Store ratings are the stores’ numbers, not Appworthy’s, and are never averaged across stores.

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
