A one-person iOS studio. Small, sharp apps built because nothing on the App Store did the thing I needed that day.
See the apps
Share a link, post, or video to Back Pocket and drop it in a pocket. Reels, articles, job listings, recipes — all in one place, sorted into pockets, and searchable when you actually need them.
Enter who's in the room and what they cost per hour, then start the timer. The dollar figure climbs while the meeting runs. Stop it at the end and send the number to the people who scheduled it.
Your phone measures your fart, names it and stamps an official lab report. Then your own recording plays over an original cartoon. Send it to a friend, and they fart back.
Free to download. No accounts, no ads. Lab Pass: one-time purchase, $2.99. No subscription.

I'm Michael Moscone. I trade for a living — oil futures, stocks, options — and I have no software background at all. RottenTooth Labs started because I kept waiting for someone else to build small things I wanted on my phone, and nobody did.
So I build them with AI. I describe the app I want, we write it together, and I run it on my own phone for weeks until it stops annoying me. Then it ships. Every app here started as a note I wrote to myself.
That's the whole studio: one person, a stubborn list of ideas, and apps that do one thing without asking for a subscription.
