Undertow Focus

The problem isn't willpower in general. It's one specific moment: you're mid-task,
your phone buzzes, and your attention gets pulled to the surface. Everything else —
the apps, the blockers, the streaks — is downstream of that one moment.

Undertow is built around it. Start a dive (a focus session), and if the pull hits,
tap Pulled. You get a 10-second ride-out — haptics, breathing pace, a moment to just
be somewhere else — instead of automatically reaching for the thing that buzzed. Most
urges pass in under 10 seconds if you give them somewhere to go. Free, no strings
attached.

For $3.99 (one-time, not a subscription), Undertow can also shield distracting apps
using Apple's Screen Time framework during a dive, so the buzz doesn't even get a
chance to reach you for the ones you choose to block. (Apple exempts a handful of
system apps — Messages, FaceTime, Phone, Maps, Clock, Settings, Find My — from
third-party shielding on every app that uses this framework; this is a platform-wide
safety floor, not something Undertow — or any app — can override.)

No feeds, no gamified guilt trips, no social pressure, no subscription. Just a timer,
a streak that tracks honestly (surfacing early doesn't fake a win), and one button
for the moment that actually matters.
