Usage limits
Set a daily budget per app. Instagram gets 20 minutes and then it's locked. Your screen time, your rules.
F/03
Focus sessions
One tap starts a focus session. Selected apps are blocked until the timer ends — no overrides, no bargaining.

100% on-device
No cloud, no tracking, no ads. Uses Android's Accessibility Service and UsageStats APIs. Your data never leaves your phone.

ABOUT
Curious, persistent, always shipping.
I'm an Android Engineer based in São Paulo. For almost a decade I've built mobile products used by millions — from banking and retail to automotive and food delivery.
AppBlockerService is my own take on a tool I wanted to exist: something honest, fast, and respectful of your attention. No subscriptions disguised as freemium, no telemetry.
Outside work I play simulation games, research obscure consumer electronics, and keep a running list of side projects I'll probably ship someday.
