App Blocking
Shut off distracting apps — social, games, video, anything that eats your attention — down to the exact app.
For iPhone · Screen Time powered
Remember why you blocked it — before you open it.
Most blockers just say no. Simba pairs real app & website blocking with a small cat companion who shows up right when willpower gets shaky — with the exact reason you set the block in the first place.

The difference
Most blockers only stop access.
Simba stops you, gently.

Screen Time Limit
TikTok is not available right now because of a downtime limit.
OK
Flat. Forgettable. Ignored in three seconds.

"You're building a portfolio, not a highlight reel."
Got it, closing
Personal. In your own words. Impossible to skim past.
Everything you need to protect focus
One companion, four layers of protection.
Website Blocking
Block specific sites or entire categories in the browser during focus periods — no more "just checking one thing."
App Folders
Group apps into named folders — Social Media, Games, Night Block — and reuse them across every schedule and routine.
Custom Block Screen
Simba replaces Apple's gray shield with the mascot, your brand color, and a reminder line in a tone you pick.

Two ways to block
Set it once, or start it on demand.
Scheduled Blocking
Runs itself, every day.
Pick days and time windows — even overnight ranges — and Simba enforces them natively via DeviceActivity, so it fires even when the app is closed.
- Multiple time windows per schedule
- One folder per schedule, optional Hard Mode
- Perfect for work hours, school time, or night restrictions
Morning Focus
Active
Focus Sessions
Quick Focus & prepared routines.
Start immediately from the Focus tab. Run a timer or go open-ended, minimize into a Live Activity, and end early with a deliberate 5-second hold — or lock it down with Hard Mode.
- Full-screen countdown + Lock Screen Live Activity
- Hard Mode removes the Stop button entirely
- Only escape: the high-friction Emergency Unlock

When willpower needs backup
Hard Mode. No easy way out.
Hard Mode removes the Stop control completely. The only exit is Emergency Unlock — a deliberate, high-friction sequence built for the moments a simple button would be way too easy to press.
- 01A pause moment with Simba, explaining what's about to happen
- 02A 15-second cooldown — no skipping
- 03Type a reflective phrase: "i have a real reason to end this session"
- 04One final, explicit confirmation — plus your PIN, in Parent Mode
Every screen keeps "Keep focusing" as the easy button.
Parent Mode
Protective, not a power struggle.
When Simba is set up for a child, a 4-digit PIN guards every action that would weaken protection — stopping a session, editing a schedule, or the final step of Emergency Unlock. Myself Mode skips all of it.
PIN required to weaken protection
Insights
Your focus, measured kindly.
Numbers framed as progress, never punishment — built from session history and blocked-attempt counts, since iOS never hands over per-app usage time.
