I built my own private messenger — hope it's useful to someone else too
For years I was looking for a messenger that was actually private — and I don’t mean just “encrypted” or “they won’t hack me.” I mean: if someone picked up my phone, they’d see exactly who I was talking to, their number, and the whole history of photos, videos and files we’d sent.
A lot of messengers have settings and toggles you can tweak, sure. But it never felt like enough — I wanted a chat that’s private by default, from the second you open it, not after digging through options.
So I built “mono - private messenger”
the app to have that conversation.
No account, no name, no email, no phone number, no profile photo. Nothing tied to who you are. You get a key that rotates every 3 minutes, share it with one person, and that’s it — one conversation at a time. Messages are end-to-end encrypted, only the last 15 stay visible, and the whole thing self-destructs after 36h of inactivity. No groups, no calls, no voice notes — on purpose.
It’s not trying to replace Telegram or WhatsApp. It’s for a different thing: a private, ephemeral, one-to-one line — the kind of conversation that leaves nothing behind.
Free on iOS — macOS coming soon. I’m the developer, happy to answer anything.
