Osta

Osta — Osta Ltd. has hit an all-time peak rank of #7 on Google Play (achieved on 2026-08-21), but over the last 30 days it has averaged around #18 and now appears to be on a downward slide across all of its tracked charts. It currently sits at #13 in the US Top Grossing chart after a 1-step drop, while its Top Free presence in emerging markets — Kenya (#24), the Philippines (#26), and Czech Republic (#29) — has slipped 3–4 positions each. The app is also broadly charted in Top Grossing across Bangladesh, Colombia, Egypt, and Hong Kong, where it holds a cluster of #31 spots, each down 1–2 places. Overall, the trajectory is one of mild decline from a recent high, with the steepest losses concentrated in the Top Free rankings and more modest erosion in the Top Grossing lists.
