The problem
Handing your phone to someone shouldn't mean handing over your gallery, chats and banking apps.
What I built
System-level app locking with fingerprint and PIN protection. The engineering challenge in this category is the always-on service: intercepting app launches reliably without draining battery or getting killed by the OS — and doing it across Android versions and manufacturers.
Where it stands
Live on Google Play. Security apps get uninstalled the first time they fail — shipping and maintaining one is the case study.
