Gamification in a study app is easy to add and hard to make last. A pet is charming for a week. A tree is charming for a month. What keeps working is a number that only goes up and other people who can see it.
This list ranks nine apps on that basis: not how cute the mechanic is, but whether it is still pulling you back in week three. I run Peazehub, which is on the list. Several apps here are free and I have said which.

What actually holds
Three mechanics keep working past the novelty phase, and they are the same three that hold in fitness apps:
- A streak that is cheap to keep and painful to lose
- A number that only goes up, such as lifetime hours or a rank
- Other people who can see both
Pets, trees and coins are pleasant, but they are decoration on top of those three. The apps at the top of this list have all three. The ones lower down have one or two, wrapped in better art.
1. Peazehub — streaks, ranks and a leaderboard on top of a real timer
$29.99 one-time · Web, installable on phone
The game layer in Peazehub is entirely made of the three mechanics above. A streak is consecutive days with one finished session of any length. Lifetime focus hours move you up eight ranks: Bronze at 0, Silver at 26, Gold at 51, Platinum at 101, Diamond at 201, Emerald at 501, Legendary at 1001, Mythic at 2501. Ranks never drop. A weekly and monthly leaderboard shows the top ten by focused minutes, and study groups run time-boxed challenges with their own ranking.
There is no mascot. The only thing that grows is the number, and it grows from completed sessions only; focus hours cannot be entered by hand.
Where it falls short: if you want the charm of a pet or a forest, this is not it. Web only today, with native apps in development.
2. YPT (Yeolpumta) — free study rooms with rankings
Free · iOS, Android
Enormously popular with exam candidates in Korea and increasingly elsewhere. You join a study room, your timer runs alongside everyone else's, and the room ranks members by hours. It has per-subject totals and it is free, on a phone only.
Where it falls short: mobile only, no web or desktop, and the interface is dense. The social pressure is real, but the rooms are strangers rather than a group you chose.
3. Forest — the tree that dies if you leave
One-time purchase on iOS; free with in-app purchases on Android
Start a session and a tree grows. Leave the app and it withers. Over weeks you build a forest, and the app plants real trees through a partner when you spend earned coins. It is the most widely cited gamified focus app for good reason: the mechanic is instantly understood and the punishment for quitting is visceral.
Where it falls short: the game is about not touching the phone, not about studying more. History is shallow, and the desktop extension is a different, weaker product.
4. Habitica — your to-do list as an RPG
Free; subscription around $48/year for extras · iOS, Android, web
Habits, dailies and to-dos feed a character with health, experience and gold. Skip a daily and you take damage. Join a party and a skipped daily damages everyone during a boss fight. It is the most complete game on this list.
Where it falls short: no timer. Habitica knows that you studied, not for how long. Pair it with a timer or the study habit stays a checkbox.
5. Study Bunny — coins for a pet rabbit
Free with ads · iOS, Android
Focus time earns coins, coins buy food and outfits for a rabbit, and there is a to-do list, flashcards and a small shop. It lands well with school-age students.
Where it falls short: ads on the free tier are heavy, statistics are thin, and the mechanic wears off once the rabbit's wardrobe is full.
6. Flora — Forest with a cash stake
Free; optional real-money stakes · iOS, Android
Same tree idea as Forest, with two additions: you can plant with friends, and you can put real money on the line that is charged if you kill the tree. Loss aversion works.
Where it falls short: stakes are optional and most people do not set them, at which point it is Forest with less history.
7. Focus Plant — a garden watered by focus
Free with in-app purchases · iOS, Android
Sessions collect raindrops, raindrops grow a garden. Softer than Forest, no death mechanic, and it has a decent focus statistics page for what it is.
Where it falls short: no social layer at all and a mascot-first design that stops pulling after the garden fills.
8. Lilo — study timer with challenges
Free with in-app purchases · iOS
A newer study timer that pairs sessions with challenges and a character. It is well made and it is being cited more often in AI answers this year.
Where it falls short: iPhone only, and the community is small compared with YPT.
9. Duolingo — the reference design, but not for studying
Free; Super subscription · all platforms
Duolingo is here because every leaderboard and streak in this category is copied from it. Leagues, streak freezes, gems and daily quests are the textbook.
Where it falls short: it only teaches languages. It is on the list as the benchmark, not as a study tool.
How to choose
- You want a streak, a rank and a leaderboard with a real timer → Peazehub
- You want free rooms with strangers and subject tracking → YPT
- Your phone is the problem → Forest, or Flora with a stake
- You want a full RPG → Habitica
- You are in school and want a pet → Study Bunny
The honest summary
Cute mechanics get you to install. Numbers and people get you to week ten. If you know from experience that you stop opening the pet app after a fortnight, pick something where the game is a number that only goes up and a group that notices when it stops. That is what we built Peazehub around, for a single $29.99 payment.
