Rank history
The "Guide for Google Duo" app by Davit Mkrtchtan is currently performing at its all-time peak, holding #43 on the Top Free chart in São Tomé and Príncipe — a position it has maintained flat and which matches both its best and average rank over the last 30 days. Beyond this headline market, the app is charting modestly across a handful of small markets, with #58 in Oman (down 2) and a double appearance in Qatar at #66 and #68 (both unchanged), plus #100 in Nepal (flat). Overall trajectory is essentially steady, with no significant movement in any direction; the Oman dip is the only notable change. Visibility remains narrow, limited to five chart positions across four countries, all in the Top Free tier within the Books category.
