The inner weather app by Emolution
Your inner weather, every day.
Each day, you name your emotion. The sky in your notebook changes, and your Nimb, a small creature made of that weather, answers you. One minute to look after yourself, and to see the storm coming before it breaks.
Coming soon onthe App Store
Planned for 2027 on iPhone (iOS 18 and later).

How it works
One minute a day is enough. Nimbu never punishes you for missing a day.
- Name your emotion“How do you feel?” Joy, sadness, anger, fear: you pick what is there, without judging.
- Your sky changesThe sky in your notebook takes the colour of your day, like a drop spreading on paper.
- One minute with your NimbA 60-second exercise guided by voice: breathe, tap, settle. Your Nimb reacts to each gesture.
- Your seasons appearDay after day, your notebook keeps track of your weather. Your emotional seasons start to show.
A naturalist's notebook
The Nimbs
Each emotion has its Nimb, made of its weather. Tap one: the sky at the top of the page changes with it.
It grows with you
From a drop to an elder.
Your Nimb goes through six stages: drop, sprout, companion, scout, guardian, elder. It grows with the days you come back, never with a perfect streak. It does not die and never blames you.


See the storm coming
A gentle alert, before burnout.
If you allow it, Nimbu reads your sleep and heart rhythm in the Health app on your iPhone, with a watch of any brand. When tiredness builds up, your sky clouds over and your Nimb tells you, without guilt.
Your data
Your weather belongs to you.
- No account, no ads.
- Your emotions and health data stay on your iPhone. Nimbu has no server and Emolution cannot access them.
- A watch is recommended, never required.
FAQ
Who is Nimbu for?
Adults who want to look after their emotions every day and see tiredness coming before it overflows.
Do I need a watch?
No. A watch of any brand improves the forecast if it writes to the Health app on your iPhone. Without one, Nimbu works with what you note each day.
How much will it cost?
Nimbu will be free for the daily weather, one Nimb and emergency exercises. A subscription will open the whole notebook. Prices will be announced at launch.
Does Nimbu replace therapy?
No. Nimbu is for everyday wellbeing. It does not diagnose anything and does not replace a doctor, a psychologist or a treatment. If you are in distress, call your local emergency number.
Which devices?
iPhone, with iOS 18 or later. In French and English.
