Calculator Lock - Secure Vault

Calculator Lock - Secure Vault by ZipoApps is currently concentrated in smaller and African markets, with its standout position being #4 on Gambia's Top Grossing chart — tying its all-time peak achieved on 2026-07-22. In the Top Free category, it holds its best current spot in Côte d'Ivoire at #9, where it is climbing (+3), followed by Namibia (#13), Antigua and Barbuda (#14, -4), Guinea-Bissau (#16), Chad (#17, -4), and Tunisia (#17). The trajectory is mixed: the app is gaining ground in Côte d'Ivoire while losing positions in Antigua and Barbuda and Chad, and holding steady elsewhere. Its 30-day average of #10 versus current best of #4 suggests it is performing near the upper end of its recent range, primarily driven by the Gambia monetization chart.
