Snatch Guard addresses a highly relevant and growing security issue (phone snatching) with an innovative, privacy-first technical implementation using existing iOS APIs. The market timing is exceptional. However, as the app is only one week old with 14 total installs, it currently exhibits minimal traction and audience reach, aligning its score with early-stage, promising projects that have yet to scale.

Description
Snatch Guard detects when someone grabs your iPhone using the built-in accelerometer and instantly locks your selected apps with a Screen Time shield. Only Face ID or passcode can remove it. Free, no ads, no tracking – built because Android has had Theft Detection Lock since 2024 and iPhone still has nothing equivalent.
Audience Reach
Launched a week ago. 14 installs, 1,390 unique visitors on the landing page. Technical article submitted to HackerNoon, pending review. Built for anyone with an iPhone who lives in or travels to cities where phone snatching is common – London had 117,000 phone thefts in 2024.
Target Users
People who carry banking apps, messages, and personal photos on their iPhone – especially in cities with high phone snatching rates like London or Rio de Janeiro. No notable users yet, the app is a week old.
