About these numbers
The default ranking adds public rating counts collected from Google Play and the App Store storefronts checked. It includes both Android and iOS. This volume is a popularity signal, not a count of downloads or people.
Google Play provides its public counter. For Apple, we add available counters from France, Germany, Spain, Italy, Switzerland, the United Kingdom and the United States. Each profile shows this scope, which does not cover all countries. If one platform is missing, only the documented count is used. Android download thresholds and publisher-reported users have separate sorts and are never added to ratings. One person can rate on several platforms. Ties are sorted by name; profiles without figures follow.

Check before choosing
A publisher’s country does not establish its independence. Ownership, subprocessors, data location and technical dependencies need a separate assessment.
Plan your switch
Test with non-sensitive data first. Check import and export options, essential features and plan terms before migrating.
How the score is calculated
Swiss control is documented. Azure hosting and several US payment, support and notification providers lower the score despite file encryption.
The score covers documented criteria. For each of four dimensions, earned points are divided by the maximum for reviewed criteria, scaled to 25 and rounded. The four results form the score out of 100. Unknown items are excluded and reduce the separately displayed documentation coverage. Publication requires at least 60% of the rubric reviewed and 10 weight points in every dimension. A high score does not rule out dependencies in unchecked items.
