Comparison
StretchLock vs Opal
Both apps help you spend less time mindlessly on your phone. The difference is philosophy: Opal blocks apps during focus sessions, while StretchLock puts a short stretch between you and the apps that pull you in. Here's how they actually compare.

| Best feature | Turns screen time into a body reset | Polished focus sessions and analytics |
What Opal is
Opal is a premium focus app, best known on iOS, that lets you schedule 'focus sessions' which block distracting apps and websites. It leans into deep work — detailed session analytics, streaks, and a slick interface — and has built a loyal following among people who want serious, scheduled blocking.
Where StretchLock stands out
StretchLock takes a different angle. Instead of locking you out for a block of time, it asks for a short stretch each time you reach for a distracting app. That tiny pause breaks the autopilot, and — unlike every focus app — it gives something back to your body, which is the part of screen time most tools ignore. It also runs on both iOS and Android, and it's free to get started. Our guide to reducing screen time explains why this friction-first approach tends to last longer than hard blocking.
Where Opal is stronger
If your problem is sitting down for two hours of deep work without drifting, Opal's scheduled sessions and analytics are more powerful than a per-open pause. Its focus dashboards and session history are genuinely well built. For pure, scheduled lockout on iOS, Opal does more.
