Questions and answers

It runs structured 21-day challenges. You pick one — confidence, discipline, communication, a morning routine and 40-odd others — and each day it gives you a short piece of framing and one small concrete action, which you mark as done. A 21-square grid and a streak count track the run, and a progress screen totals up finished challenges and badges.

No. The 21-day figure is folklore, not research, and it is worth saying so plainly on a site about a 21-day app.

It traces back to Maxwell Maltz’s 1960 book Psycho-Cybernetics, where a plastic surgeon observed that his patients took “a minimum of about 21 days” to get used to a new appearance. The qualifier fell off as the idea spread, and a surgeon’s observation about adjusting to a face became a universal law about habits.

The best-known study on actual habit formation — Lally and colleagues, published in the European Journal of Social Psychology in 2010 — followed people adopting everyday habits and found a median of roughly 66 days to reach automaticity, with individuals ranging from about 18 days to more than 200, depending on the person and on how demanding the behaviour was.

So what is twenty-one days good for? Two real things: it is long enough to prove to yourself that you can sustain something, and short enough that you can see the end from the start — which is what makes people finish rather than drift. That is a sound reason to structure a challenge that way. It is not a threshold at which a habit becomes permanent, and nothing on this site claims it is.

None of the three. It is a structured list of small daily actions with some framing around them. It does not diagnose anything, does not treat anything, and is not a substitute for professional help. If you are dealing with anxiety, depression or anything else that needs real support, please get it from someone qualified.

It overlaps with one, but the difference is where the content comes from. A habit tracker records what you already decided to do; here the challenge supplies the day’s action. If you already know exactly what you want to do each day, a plain tracker is lighter and usually free. The comparison table lays it out.

The developer states 44 or more, across themes such as confidence, discipline, communication, morning routines, leadership, emotional intelligence, gratitude and decluttering, with new ones added periodically. The current list is the one in the app.

The streak breaks and the square stays empty. The useful response is to do today’s action rather than restart the whole challenge: a 21-day run with one gap is worth far more than three abandoned perfect starts.

If you have missed four or five days in a row, that usually means the time slot was wrong rather than that you were — change the slot and start again from day one. More in the guide.

The actions are designed to take a couple of minutes. That size is the point rather than a limitation: something small enough to do on a tired, late, unmotivated day is what keeps a run alive, and those are the days that decide it.

The app offers an upgrade when you try to enrol in a second one while the first is running. Whether it is a good idea is a separate question: one challenge you finish beats three you abandon, and the app is built around one at a time for that reason.

The grid is full and you get a badge. What does not happen is that the behaviour becomes automatic — see the question about 21 days. Treat day 22 as a decision point: carry on without the app, run the same challenge again, or start a different one.

Yes, and for anything you actually want to stick, running it twice is more sensible than collecting new ones. The second run is where you find out whether the first was novelty.

It is free to install and free to use: you can browse the challenges, start one and work through the daily actions without paying. The free version is funded by advertising — the Google Play listing carries a Contains ads badge — and the listing also carries an In-app purchases badge for the optional extras.

Google Play prices in-app items in this app at $0.49–$19.99 each. The upgrade is what the app offers when you try to run more than one challenge at the same time, and it is also how the advertising is removed.

The purchase screen inside the app is the authoritative description of what a given item unlocks, and shows prices in your own currency.

The purchase screen in the app states whether a given item is a one-off purchase or a recurring subscription, and that screen is the one to trust.

If you have bought something recurring, it is managed and cancelled in Google Play — tap your profile picture, then Payments & subscriptions, then Subscriptions — and not in the app or on this website. Uninstalling the app does not cancel a subscription.

Refunds are handled by Google Play under its own refund policy, because that is where the payment was taken. Request one through your Play order history. This website never takes a payment and cannot issue one.

For a profile photo and for challenge actions that ask you to photograph something. Nothing is captured unless you start it, and the daily prompts work fine if you decline the permission.

In its Google Play data safety declaration the developer states that the app may share precise location with third parties, for advertising or marketing and for personalisation, and that it collects app info and performance data for analytics. That location sharing comes from the advertising side of a free app rather than from the challenges themselves.

The same declaration states that data is encrypted in transit and that you can request that data be deleted. The app has its own privacy policy, separate from this website’s, and the current version of the declaration is always the one on the Play listing.

Three things, in order: Android’s notification settings for the app, whether Do Not Disturb is on a schedule you forgot about, and battery optimisation, which on several manufacturer skins kills background apps aggressively. Allow the app to run in the background; no app can grant itself that.

Support goes to hello@bestifyme.com; include the phone model, the Android version and the app version. Billing questions are faster through Google Play, which is where the transaction lives.

The website is run by BestifyMe, the publisher of the app, and exists to document it in more depth than a store listing allows. It sells nothing, hosts nothing and takes no payment. More on the About page.
