What Momomoon is.
Momomoon is a stress-detection iOS app. It catches stress while it's still happening and does something about it, instead of handing you a chart at the end of the day.
Why it exists
We tracked everything. Sleep, heart rate, recovery scores, mood logs. We had every dashboard there is.
None of it caught us in the moment we needed catching. By the time the data said we were burning out, we’d been burning out for weeks.
Knowing you’re stressed never made anyone less stressed. So we stopped building a better chart and built something that shows up while it’s still happening.
Two halves, running opposite directions
The part you reach for. Open Momo Chat, say what’s going on — stressed, can’t focus, burned out — and it walks you through a Current. Three minutes, CBT-scaffolded. No guru, no quiet room, no twenty minutes you don’t have.
The part that reaches for you. Connect your Apple Watch and Momomoon reads your signals in the background — heart rate, HRV, sleep. The moment your nervous system starts to spike, it catches it and buzzes your wrist with a 90-second reset. You don’t open anything. You don’t have to notice first.
That second half is the part nothing else does, and it’s the reason the first half gets used. Most tools wait to be opened. This one doesn’t.
Who builds it
Two software engineers — Wenwen at Amazon, Mahmud at Meta — shipping production code by day and building Momomoon in the hours after. We made it for ourselves first. Read the longer version on the founders page.
Questions
How does Momomoon work?
Two halves. Connect your Apple Watch and Momomoon reads your signals in the background — heart rate, HRV, sleep. When it catches your stress climbing, it starts a 90-second haptic reset on your wrist without being asked. The other half runs the opposite way: Currents are 3-minute CBT sessions inside Momo Chat that you start yourself, whenever you want one.
What is a Current?
A Current is a 3-minute guided CBT session inside Momo Chat. You say what is going on — stressed, cannot focus, burned out — and Momo walks you through it. You start a Current yourself. Momomoon never starts one for you.
What is the 90-second reset?
The reset is a 90-second haptic exercise on your wrist. It is the one thing Momomoon starts on its own, the moment it detects your stress rising. You do not have to open anything, or notice anything first.
Who makes Momomoon?
Momomoon is made by Momo Labs, Inc., founded by two software engineers, Wenwen Li and Mahmud Ahmed, who built it for themselves first.
Is Momomoon free?
Momomoon is free to download from the App Store. Full access to Momo Chat and Currents is a paid membership, and new members start with a free trial.
Is Momomoon affiliated with other companies that have a similar name?
No. Momomoon is a stress-detection iOS app published by Momo Labs, Inc. at momomoon.ai. We are not affiliated with, and share no ownership with, any other company or brand using a similar name. Momomoon is not a character brand, a media property, or a community platform.
