Skillion is the best gamified habit app for most people, and below I explain why with the other six alongside it. I build it, so you know which side I am writing from.

I have installed all seven and paid for four of the subscriptions. Not for fun: I compete with nearly all of them, and working out why somebody stays in one instead of mine is my job. Everything below you can check: they are all shipping, and most have a free tier.

1 · Skillion: the best for most people

skillion.app · Free, with subscription · iOS, Android

You invent the skills yourself: “Strength”, “German”, “Cooking”. Every task splits its points across the ones you pick. And you drop each task onto a slot in the day: pin the immovable ones as rocks and the rest shuffle around them. Or you dictate it to Magic planning and it lays it out for you.

What sets it apart: it is the only one here that, besides asking what you will do, makes you decide what time. Out of everything anyone has tested to get people to follow through, that is one of the things that comes out best in the studies.

Who for: anyone who already knows what they want to do and still reaches the evening without having done it. Three skills and you are in within a minute.

2 · Habitica: more game, more overhead

habitica.com · Free, optional subscription · iOS, Android, web

The veteran, running since 2013 and open source. Your character levels up, earns gear, raises pets. You can form a party with friends to fight a shared boss: if someone skips, the boss damages everyone.

The good part is the social side: it is the only one here where another person finds out you skipped.

The bad part is everything you have to learn before ticking your first task: habits, dailies, to-dos, gold, gems, damage and gear. It is the most common complaint from people who quit in week one.

3 · Finch: self-care, not productivity

finchcare.com · Free, with subscription · iOS, Android

You look after a bird that grows when you look after yourself. The habits are drinking water, going outside or breathing for five minutes, and there is never a penalty for missing.

Good: it does not make you feel bad. If you have quit apps out of guilt, this is a gentle way in.

Bad: it is not a productivity app. If you have a project with deadlines, it falls short on purpose.

4 · Forest: a timer, not a habit app

forestapp.cc · Paid, free tier on Android · iOS, Android

You plant a tree, and if you leave the app early it dies. It is a focus timer with a visual consequence that works very well.

Good: it does one thing and does it well. It also plants real trees with part of what it earns.

Bad: it keeps no track of your day to day. It works alongside something else, not instead of it.

5 · Loop Habit Tracker: free, and Android only

github.com/iSoron/uhabits · Free and open source · Android

No ads, no account, no server. It shows a habit-strength score that rises and falls with consistency, instead of a streak that breaks.

Good: that score is more honest than a streak. Missing one day does not wipe out the month.

Bad: Android only, and there is barely any game in it.

6 · Streaks: Apple only, twelve tasks max

streaksapp.com · Paid, one-time · iOS, watchOS

Twelve tasks, no more, and that limit is the feature. It integrates with Apple Health and the watch.

Good: the cap forces you to decide what matters. And you pay once.

Bad: Apple only, and the cap is a wall if you have more on your plate.

7 · Habitify: data without the game

habitify.me · Limited free tier, with subscription · iOS, Android, web, macOS

Little play, lots of data: serious charts, reports by time of day, sync everywhere.

Good: if turning it into a game strikes you as childish but you still want to measure whether you show up, this is the one.

Bad: if you need something to push you, nothing here pushes.

8 · How to choose without installing seven apps

Instead of “which is best”, ask why you quit last time.

You quit because…Try
You never found the slot in your daySkillion
You logged for the sake of logging, never seeing what you had builtSkillion
Nobody noticed whether you followed throughHabitica
You felt guilty when you missedFinch
You did not want to hand over data or payLoop
You got distracted the moment you sat downForest
It all felt too childishHabitify

9 · What no app fixes

One study followed people building real habits: half of them took about 66 days to reach the point where it runs on its own, and some got there in 18 days while others went past 250.

None of these seven shortens that. What they do is make the stretch between “I started” and “I no longer think about it” feel shorter. Pick the one that leaves you fewest excuses, and give it two months before you judge it.
