Phone habit breaker

Your screen time—
Grimby absorbs it.

Grimby combines usage insights with app blocking (Premium) and a reaper that evolves with your choices—not another dry chart, but a character and skins that hit you in the gut so procrastination doesn’t keep winning.

Grimby reaper character

Death by a thousand scrolls

Every “just a minute” on your phone
is life energy the reaper drinks away.

A few minutes adds up to hours a day. Focus, sleep, and real conversation don’t come back from a Screen Time graph. Grimby turns that leak into the reaper’s growth—so you feel the cost in your bones, not just in numbers.

Who Grimby is for

Soft reminders didn’t work. You want rules you can see—and a look that actually moves behavior.

You can’t put the phone down

Hours vanish before you notice. Willpower alone doesn’t stop the loop.

You break your own limits

You dismiss Screen Time limits and negotiate with yourself—again.

Socials own your nights

The hour before bed dissolves into an endless feed.

Usage stats feel scary to open

You’ve been looking away from what the reports would show.

The reaper enforces your rules.

No bargaining—just visible change. Whether you stayed on track shows up right on screen.

The reaper watches your target.

Set a daily usage goal—optionally split by category. Simple numbers decide the reaper’s state.

The reaper is always watching. Go past your limit and Grimby won’t look away: that phone time becomes “life” drained—and the reaper grows.

Step 1 screen

Lock your phone on a routine

Set recurring routines and force your phone to lock—weaken Grimby along the way.

Step 2 screen

Close the loopholes—structurally.

With Premium, chosen apps can’t launch after you hit your limit. Time windows mean “not later”—“not now.”

Fewer cracks for impulse to slip through.

Step 3 screen

Focus fast with the app lock timer

When you need to concentrate right away, pick how long to lock for and tap start—blocked apps stay closed until the countdown hits zero, and the ring shows time left at a glance. Even a short block is a chance to weaken Grimby.

Everything you need to guard the habit.

Visualization that hits

Weekly reports and skins—so “how today went” lives in the look, not only in digits.

Tracking screen with Life drained and week calendar

Accurate tracking

Screen Time integration measures per-app use on iOS—including background time.

Screen lock active

No way out until it’s over

Premium app locks and time windows block the usual “just one more negotiation.”

FAQ

QHow do you measure usage?

We use Apple’s Screen Time APIs to measure per-app time, including background use.

QHow does app lock work?

It builds on Screen Time restrictions. Past your goal, selected apps won’t open. Emergency override is limited (e.g. once per day).

QWhat kinds of reaper skins are there?

20+ styles—yokai-inspired, cute, cool, and more. Premium unlocks all, with more added over time.

QIs there an Android version?

We’re focused on iOS first. We’ll announce Android timing separately.

QFree vs Premium?

Free covers visualization, goals, and tracking. Premium is for when you need apps to actually stay blocked.
