App studio
I build apps.
Pulsar Shift is my one-person studio. I take ideas that won't leave me alone and turn them into apps people can actually use. The first one out is Focus Race.
About
I'm Geoffrey Tisserand. About a decade in software engineering, mostly Silicon Valley. My thing has always been product design and UX, how software looks, flows, and feels once someone picks it up.
Pulsar Shift is my studio for app ideas worth finishing. I handle the design, the build, and getting them out the door.
The timing finally works. AI made execution cheap enough that one person can ship fast. Ideas I've had for years can finally become real apps.

Focus Race
First launchA focus app born from a weekly bet with my wife.
We competed on screen time every week. Whoever used their phone less got to make a request of the other. Competing over attention worked better than any blocker I'd tried.
When Focus Friend came out, it pushed me to build my own. Focus Race mixes my love of space and appetite for competition to fight my screen-time addiction — stay focused to fuel your ship, make progress on missions, and race other people across the world.
