Habit Share (HabitRix) vs stickK (2026): which should you pick?

Pick Habit Share (HabitRix) if

• Fits if a group of friends wants to check in on the same habit
• Works for people who get more done with a streak board in view

Look elsewhere if

• Skip it if you track alone, since the sharing is the point
• Tight if you want more than 3 habits or one room on free
• Watch out: Pro's billing period isn't shown on Google Play
• Watch out: the site says it's a different app from HabitShare at habitshareapp.com

Pick stickK if

• Fits if you only follow through when money or your reputation is on the line
• Works for people with a friend, coach or family member willing to check reports as Referee

Look elsewhere if

• Skip it if you might change your mind, as a contract can't be deleted once it begins, short of a physician's form
• Not for you if you just want to tick off small daily habits, as everything here is a contract with an end date
• Pricey if you set a big stake and slip, since your card is charged within 48 hours of each failed period
• Watch out: a daily report not filed within 24 hours counts as a failure, and stickK keeps 50% of anti-charity stakes
• Watch out: paid Campaign prices show only inside an admin account, and older help articles describe outdated terms

Habit Share (HabitRix)

• The free plan allows 3 habits and one shared room; more habits and rooms need HabitRix Pro.
• Pro prices are read from the Google Play in-app purchase range; the billing period of each option is not shown.
• The site says it is a different app from HabitShare at habitshareapp.com, made by another developer.

stickK

• stickK keeps 50% of forfeited stakes sent to an anti-charity, plus contract costs, under its contract terms last updated June 12, 2024.
• Those terms removed a $5 creation fee and ended charity and friend-or-foe recipients for new contracts; older help articles still describe all three.
• A contract cannot be deleted once it begins; the terms allow cancellation only with a physician's medical excuse form.
• Prices for the paid Campaign plans (All-access and Pro) are not published in the help center; they appear inside a Campaign admin account.

Habit Share (HabitRix)

Shared habit rooms

Create a room for a habit and invite people with a link or a 6-character code. Rooms are private and invite-only, with no member limit.

Streaks and leaderboard

Members see each other's check-ins and activity grid, get a notification when a friend checks in, and see a room leaderboard.

Flexible goals

Habits can be daily, weekly or monthly, with several check-ins per day (for example 8 glasses of water) and backfilling from the calendar.

Reminders and widgets

Reminders at chosen times and days, plus a home-screen widget on the free plan.

Private habits alongside shared ones

Only habits you bring into a room are visible to its members; the rest stay private to you.

stickK

Commitment Contracts

A contract with yourself that fixes a goal, a start and end date and a reporting schedule. After creation you can only add a Referee, invite Supporters and change its privacy settings.

Reports on a fixed schedule

You report success or failure daily, weekly or once at the end. A report not filed within 24 hours (daily) or 72 hours (weekly and single-report contracts) counts as unsuccessful.

Referees

A person you invite verifies your reports and has the final word: a Referee can turn a reported success into a failure. Without one, the contract runs "On Your Honor".

Money stakes

Set an amount that is charged to your card within 48 hours of each unsuccessful reporting period. Under the June 2024 terms, new stakes go to an anti-charity you pick or to stickK itself.

Supporters and Commitment Journal

Supporters can be emailed your result after each report and can comment in the Commitment Journal, where you add notes and progress photos.

Communities and Campaigns

A public contract can be listed in up to three of ten topic Communities. Campaigns bundle a set of contracts for a group, whose members join with an activation code.
