Psst,it's time to steal the moon
Turn your next calendar event into something you can't miss: a full-screen takeover, or a gentle overlay over your work.
One-time $29 to keep · no subscription
On your desktop
The event finds you.
Hyper-focused? Make sure you're never the one keeping everyone waiting.
Takeover, or a gentle nudge
Minutes before a calendar event your whole screen can become it: the name, the countdown, who's coming, a one-click join. Rather keep working? Overlay mode floats a paper plane, or Bartholomew the desk cat, over your work instead. Unmissable, either way.
How it works
Three taps. Then never late.
Connect your calendar
Link Google Calendar in a tap. Read-only, cached on-device.
Choose your warning
A full-screen takeover, or a floating overlay over your work. Set how many minutes' notice you want.
Show up on time
Psst stays out of the way, then makes the next thing unmissable.
Reminders with attitude
Subtle isn't really our thing.
Psst can break the news like a bulletin, clatter it across a departure board, skywrite it on a passing plane, even ransom your next 45 minutes.
Six playful styles · set one per calendar, or shuffle · all fully animated
Prefer it understated
Or keep it elegant.
Six calm, classic layouts and eight backgrounds. Or drop in your own photo.
New · Overlay mode
Or don't take over the screen at all.
Pick your messenger: a paper plane that glides across towing the details, or Bartholomew, your desk cat, peeking up from the corner with a little sign. Try both below.

Questions
Good to know.
Does Psst change anything in my calendar?
No. It requests a single calendar.readonly scope, to read upcoming events and nothing else. It can't edit, create, send, or delete.
Where does my data go?
Your calendar stays on your device, events cached locally, tokens encrypted in the OS keychain. Your calendar contents are never sent to us or anyone else.
Is this vibecoded?
Parts of it, yes. Vibe coding is a great tool to get part of the way there, but this is still put together by an actual engineer (me) — who worked at Meta and bootstrapped a YC startup end to end before ChatGPT was even a thing. I built it because I have symptoms of time-blindness, and I need to (and do) use it every day as I work from home.
Who's behind Psst
Hi, I'm Conder.
I built Psst because I have symptoms of time-blindness, and I've been late to way too many calendar events while I was heads-down in code. Working from home, I needed a tool that would actually help me notice an incoming event and make it on time, so I built it.
Today I'm a growth engineer at a high-velocity startup. Before that I was at Meta, bootstrapped my own startup into Y Combinator (we went on to raise $2.5M and got acqui-hired), and graduated from Columbia with a degree in Computer Science.
My mission now is to build beautiful experiences for my own daily problems. Psst is the first, and I use every tool I build, every single day.
