Who makes modAmi
nicolas coucke, an independent developer in France, reachable by e-mail. The app was born from one call too many received by a parent. It is sold once or by subscription, with no advertising and no resale of data: that is its only business model.
Why it exists
The usual advice assumes you keep a cool head: “be wary”, “ask a personal question”. The moment a familiar voice announces an emergency, you no longer have one. modAmi does the opposite: it gives you something simple to check, and takes over when it doesn't add up.
How it was built
- Hundreds of sources went through: victims' forums, official alerts from France, the United Kingdom and the United States, press testimonies.
- A guidance path first written as a prototype, reviewed thirty-six times, then checked by automated tests at every change.
- A dedicated review for people aged 65 and over: contrast, target size, one thing per screen.
- Five languages, and the emergency numbers of more than two hundred countries.
What modAmi does not do
- It does not analyse voices and does not detect deepfakes: it doesn't need to.
- It does not block calls and does not listen to your conversations.
- It does not replace your judgement: when in doubt, hang up and call back.
On your device
The words and the secrets stay in the Apple keychain, encrypted.
No modAmi server
No data is sent to our servers: there aren't any.
No account
No sign-up, no online profile. The password you choose encrypts your backups on your own phone: it is never sent to us.
Backup in your hands
iCloud backup is optional, encrypted with a password you choose.
The project diary
Before the app, a series of posts on secrets2freelances.fr, the publisher's site, laid out the problem month by month: the advice that fails under fear, the limits of a code word, the data leaks, then the specification. They are in French; the last one has an English version.
