Right, the science bit
What we built this on
This is not a nice idea somebody had. The rules we follow when we write your affirmations come from published research, and every study is named and dated below so you can go and read it yourself.
The research this was built on
These are the ones that decided how a track is written.
The largest review of this to date pulled together 144 studies of students who were asked to write about what mattered most to them. Across more than 36,000 people it came out positive.
1 · Healthcare, 2024A second review, published in American Psychologist last year, looked at 129 tests of the same thing measured against wellbeing. Better self-perception, better wellbeing, fewer of the barriers people put in their own way.
2 · American Psychologist, 2025An earlier review, and the one that looked hardest at what people went on to do rather than what they said. Every measure came out positive, and the strongest result of the lot was on actual behaviour.
3 · Health Psychology, 2015This is what one of those studies actually looks like. Students wrote down what mattered most to them, then sat a hard problem-solving test. The ones under the most stress did better than the stressed students who had written nothing, and ended up scoring about the same as everybody else.
4 · PLOS ONE, 2013Why the planner runs to 66 days
People ask whether a habit really takes 21 days. It can be quicker than that.
In the study everyone quotes, the fastest people had a new habit locked in within 18 days. 66 is the middle of the range, not a target to hit, and where you land depends on you and on the habit you have picked. That range is why the planner runs to 66 days. Most people will have it by then, and some will have it a lot sooner.
fastest in the studyslowest in the study
The planner is for the habit you are building, not for the audio. There is no rule about listening every day, no streak to break and nothing that tells you off for missing one. You put a track on when you want it.
5 · Lally et al., 201012 areas, because they are not the same problem
Grief and money worries do not need the same thing said to them. Each area is built around what helps with that one.
Confidence & career
Built on self-efficacy: believing you can do something predicts whether you do. Every affirmation comes with a next step, because belief and action feed each other.
Sleep
Naming what is still undone before bed, rather than carrying it. In one lab study, people who wrote a short to-do list at bedtime fell asleep faster than those who wrote about the day just gone.6 · J Exp Psychol, 2018
Stress & anxiety
Fast breathing techniques, plus a shift in how you read the feeling. People taught to see stress as their body gearing up responded differently to it than people taught to see it as damage.7 · Crum et al., 2017
Focus
Naming what pulled you away, rather than trying to force concentration. You have to notice what pulled you away before you can do anything about it.
Money
Money worry narrows your attention onto the shortfall and crowds everything else out. The work is widening that back out, so you can think about money rather than just dread it.
Relationships
Putting a precise name to what you feel. Labelling an emotion reliably lowers how strongly your body reacts to it, even though most people expect the opposite.8 · Psych Science, 2007
Calmer parenting
Aimed at your own steadiness first, because a calmer parent is what settles everyone else. Not guilt, and not a list of things you should have done.
Grief & letting go
Not built on the 5 stages. That model came from interviews with dying patients, not bereaved people, and reviews have found it does not describe real grief.9 · Stroebe et al., 2017
Gratitude & self-love
Gratitude practice has been tested across 28 countries and 163 separate samples, and the result was a clear lift in wellbeing.10 · PNAS, 2025
The 5 minute resets
Your next track might be hours away. A reset is for right now, at your desk, at 3am, 10 minutes before a conversation you are dreading.
The breathing is not the same every time
‘Overwhelmed’ and ‘Stressed’ use the double inhale and long exhale. In a trial of 108 people doing 5 minutes a day for a month, it lifted mood and slowed breathing more than mindfulness meditation did.11 · Cell Reports Med, 2023
‘Can't switch off’ and ‘Can't sleep’ use something slower, because winding down and coping with a spike are different jobs.
Then something matched to the situation
Naming a feeling precisely instead of vaguely. Finding the evidence against a doubt. Separating what you can act on from what is just circling. Writing down what is undone before bed.
Each one is short enough to do at a desk with headphones in, which was the whole point of building them.
The sound underneath
Ocean and rain
These are the ones with the research behind them. People put through a stressful task recovered up to 37% faster listening to natural sound than to noise.12 · IJERPH, 2010
Pink noise and binaural beats
Newer, and a lot of people swear by them for sleep and focus. They are there because members asked for them, and you can pick whichever one works for you.
The 4 hour overnight track is built to cover several full sleep cycles rather than stopping partway through one. And the moon marking the rhythm of your week is simply a ritual we love.
The numbers, for employers
Deloitte also found the money comes back faster from support people use before things get bad than from support that waits for a crisis. That is the argument for something an employee can open on a normal Tuesday, in their own words, without having to ask anyone.
Books, not studies
Some of the thinking here comes from books rather than journals, and we would rather tell you which is which.
- Atomic Habits — stacking a new habit onto one you already have
- Tiny Habits — starting far smaller than feels worthwhile
- The Power of Habit — the cue that starts a routine
- Mindset — ability as something you build, not something you have
- The Secret and The Magic — if that is your language, we work with it
The part of all that the research does back: holding a goal in mind changes what you notice, and what you notice changes what you do about it.
