Free & Minimal vs A Game
Your Habits Become a Kingdom
KUBBO turns tracking into playing. Every habit earns XP and Gold; Gold buys towers, walls, and decorations that grow into a medieval city. Your character levels up, achievements unlock, and an AI coach nudges you along. It's a richer, more motivating experience by design — the reward is a whole world, not just a logged checkmark.
Clean, Free, and Yours
Loop is a beloved open-source habit tracker that does the basics beautifully and asks nothing in return — no ads, no subscriptions, no account, no cloud. Log your habits, see your streaks and charts, and let its clever habit strength score reflect your consistency. For people who distrust bloat and value privacy, that purity is the entire appeal.
A Score vs An Empire
Rewards You Can See and Spend
KUBBO is built for the moments when motivation runs low. Instant XP and Gold, a leveling character, and a city that grows in real time make the action itself feel rewarding. If you've drifted away from minimalist trackers because logging stopped feeling like anything, the game loop is what brings you back.
A Smart, Honest Metric
Loop's signature is its habit strength score — instead of a brittle streak, it uses a formula where consistency builds strength and the occasional miss only nudges it down. It's an elegant, no-nonsense way to measure progress. But it stays a number on a chart; there's nothing to unlock, spend, or build, which is exactly how Loop's fans like it.
When You Miss a Day
A Buried Building
Miss habits for 48 hours and a random building in your city gets buried — hidden, not destroyed. Buy a shovel with Gold you already earned and dig it out. The stake is playful and recoverable: you care about your city, so you come back, but a rough stretch never wipes out your progress.
The Strength Score Dips
Loop handles a missed day gracefully: rather than zeroing a streak, your habit strength score simply decreases a little, then recovers as you get back on track. It's one of the gentlest, fairest approaches to slipping — purely informational, with no game mechanic or reward attached the way KUBBO's buried buildings are.

Frequently Asked Questions
What is the main difference between KUBBO and Loop Habit Tracker?
KUBBO is a gamified habit tracker — every habit earns XP and Gold to build a medieval empire, so the focus is motivation. Loop Habit Tracker is a free, open-source, Android-only tracker that's deliberately minimal: it logs habits, calculates a habit strength score, and stores everything privately on your device. Loop is for self-motivated minimalists who want a clean, free tool; KUBBO is for people who want a game to keep them going.
Does Loop Habit Tracker have gamification?
No. Loop's only motivational mechanic is its habit strength score — a smart formula that rewards consistency and decays gently when you skip — plus streaks and charts. There's no XP, currency, levels, or game world. KUBBO's gamification is much deeper: XP and Gold on every action, character levels, achievements, and a medieval city you build with the Gold you earn.
Is Loop Habit Tracker really free?
Yes — Loop is completely free and open-source, with no ads and no in-app purchases. That's one of its biggest strengths. KUBBO is also free to download, with the core gamification — XP, Gold, and city building — available without paying, plus optional premium features. If a 100% free, ad-free, open-source tool is your priority and you're on Android, Loop is hard to beat.
Is Loop Habit Tracker available on iPhone?
No — Loop is Android-only. If you're on iPhone or iPad and want a habit tracker, KUBBO is available on iOS as well as Android and Mac. On Android, the choice comes down to whether you want a minimalist, private, free tracker (Loop) or a gamified experience with a city to build and an AI coach (KUBBO).
Is KUBBO or Loop better for ADHD?
KUBBO is usually the stronger fit for ADHD because it provides immediate, tangible rewards — XP and Gold and a city that visibly grows — which helps brains that struggle with delayed gratification. Loop is excellent if a clean, distraction-free tracker is what keeps you consistent, but it deliberately offers no rewards or game loop. If plain logging isn't motivating enough, KUBBO tends to hold attention better.
