Editor's Take
HideU: Calculator Lock sits at 4.3 stars across 919.5 thousand ratings on Google Play, and is still building an audience.
A rating in this range tells us the core loop works for most players; the usual friction points are cosmetic or balance-tweak territory rather than anything fundamentally broken.
Smart Utils Dev Team is the publisher behind this release; we'd suggest taking a quick look at their other titles on Google Play if the style clicks with you. The last visible update lands 2025-10-28, which is a small but useful signal that the team is still shipping fixes rather than treating the app as abandoned.
