Slower is a free breathing-exercise app for iPhone with 14 exercises, plus the free breathing timers on this website. You pick how you feel, and a visual pacer and a small character called Wisp guide your breath. It has no account, no ads, no tracking and no in-app purchases.
Why it exists
Breathing apps tend to open with a library: twenty techniques with names you have to already know. But the moment you reach for one, you are not thinking about techniques. You are stressed, or angry, or lying awake. Slower starts there. It asks how you are feeling and opens the breath that fits.
The second idea is in the name. Nearly every breathing method that has been studied for calming down has the same thing at its core: fewer breaths per minute, and a longer way out. So the app never offers a faster version of anything. If an exercise is too hard, the alternative is slower.
Who makes it
Slower is designed and built by one independent developer in Sweden. There is no company wellness team and no investors behind it. That is also why it can be free with nothing collected: there is nobody to send the data to.
How the content is written
The exercises follow the timings their teachers and the published studies use. The guides on this site link to the studies they mention and say when the evidence is thin, which for breathing exercises is fairly often. We would rather tell you that 4-7-8 has never had a proper sleep trial than pretend otherwise.
Slower is for general wellbeing. It is not a medical device, and nothing here is medical advice.
