Rank history
Battery Testing — Binh Tran peaked at #11 overall in the App Store Utilities category on 2026-07-28, but is currently trending downward across all tracked markets. The app currently ranks best in Cameroon at #22 (down 11) and Estonia at #28 (down 15) on the Top Free chart, with additional presence in Tanzania (#42, -10), Hungary (#50, unchanged), Côte d'Ivoire (#56, unchanged), Romania (#57, -14), Sweden (#66, unchanged), and El Salvador (#74, -38). Every listed position shows either a decline or stagnation, with El Salvador posting the sharpest drop of 38 places. The 30-day average rank of #32 versus a current best of #22 suggests the app is slipping from its mid-summer peak and has lost notable momentum in emerging-market charts where it previously held stronger ground.
