## What is Tundra?

Tundra is a focus app for people who've tried the others and still found themselves scrolling.

Most blockers are easy to bypass — a five-second tap and you're back in the feed. Tundra is built on the opposite idea: to take a break, change your rules, or turn blocking off, you first pass through friction — a wait timer long enough to break the impulse. No gamified streaks, no clutter, no tricks.

HOW IT WORKS
• Choose the apps and websites you want to block.
• Tap once to turn blocking on — blocked apps and sites are shielded across your phone.
• To take a break, wait out a friction countdown. Leaving the app resets it, so you have to mean it.
• Ending a session or loosening a setting goes through friction too. There's no cheap escape hatch.

BUILT TO BE HARD (ON PURPOSE)
• Randomized waits you can't mentally time.
• Escalating friction — each break makes the next wait longer.
• A "type your reason" gate that makes you face why you're reaching for the phone.
• Difficulty levels from gentle to brutal.

PRIVATE BY DESIGN
No account, no sign-in, no servers. Everything stays on your device — we can't see your data because we never collect it. Tundra uses Apple's Screen Time to do the blocking, all on-device.

Focus is a skill. Tundra gives you the friction to practice it.


## Version history (last 3 releases)

### 1.2 — 2026-08-31

Nine colour themes, refined — including Mediterranean, Espresso and Claret, with Forest rebalanced.

Settings friction now escalates alongside break friction, so loosening your rules can't be the cheap way out.

Fixed: Settings could become unreachable if your break ended while you were waiting to open them.

Removed the extended-break unlock, which wasn't working properly.

### 1.1 — 2026-08-26

Extended breaks — need longer than usual? Unlock a single break of up to an hour by paying extra friction. It always costs at least double a normal break's wait, and it's spent as soon as you use it.

Your Settings wait is no longer cancelled if your break ends midway through it. The wait itself is unchanged — you just don't lose your progress and have to start over.

Ending a session now always costs more than taking a break, so quitting is never the easy way out.

Refreshing the break timer can only ever make it longer — no more re-rolling for a shorter wait.

Tundra now explains why it needs Screen Time access before iOS asks, and warns you when you've selected more apps than iOS can reliably block.
