UV Tan: Tanning & Sun Trackervv1.15.1

Released April 4, 2026Major

Android

The latest major update introduced travel planning search and a tanning journey tracker on Android, but post-release data is currently insufficient to determine product impact. While the Android rating shows a positive delta of 1.69, this metric is based on a single post-update review and cannot validate a trend. The net impact is neutral until further user sentiment and rating volume accumulate.
