We build our own products — and write down what actually happened.
PFP Labs is a California-based product studio. We ship independent apps and publish deep-dive engineering series — real runs, real errors, real code you can clone and run yourself.
Made by PFP Labs
The products we design, build, and ship end-to-end — from first prototype to the app on your phone.
Go When.
Gwhen
Not another weather app. Gwhen reads the forecast for you and answers one question: when should I go? One window instead of a table of hours — for a ride, a walk, or dinner outside.
gwhen.app
Seconds until play.
tinymissions
A local-first family app with no waiting and no AI friction. tinymissions gets you from 'we should do something' to play in seconds — like Cushion Mountain: two couch cushions, 4 minutes, indoors.
tinymissions.app
Explore · Remember · Keep climbing.
mntn passport
Coming soon · iOS + AndroidA living record of every mountain you climb — with total vertical, meaningful peak comparisons, and a private social layer for seeing where friends have been. Coming soon to iOS and Android.

Built in California, shipped everywhere
PFP Labs is a small product studio at the intersection of hardware, cloud, and user experience. We design, build, and ship our own apps — from first prototype to production — and write about what we learn along the way, including the parts that didn't work.
Let's talk product
Based in California. Always happy to hear from fellow builders, collaborators, or anyone shipping something interesting.
