Independent software studio
Apps and websites, built to last.
Seventh Systems takes products from first sketch to shipped software — strategy, design, and engineering under one roof.
Now building Oohmf — a wellness accountability app
Featured work
Oohmf
Product design · Web app · iOS — in development
Wellness challenges with real stakes. Oohmf pairs you with a partner, sets weekly goals, and settles up based on what you actually did — accountability with money on the line.
- Partner challenges with weekly goals and daily check-ins
- Proof-based submissions, reviewed by your partner
- Deficit-based settlements — you pay for what you skip, not for losing
- Full-stack web app, with a native iOS app on the way
React · TypeScript · Node.js · PostgreSQL · SwiftUI
What we do
Design and engineering, end to end.
-
Mobile apps
Native iOS apps designed and built from prototype to App Store — fast, polished, and at home on the platform.
-
Websites & web apps
Marketing sites that load instantly, and full-stack products with real backends — from a single page to a whole platform.
-
Product design & strategy
From napkin sketch to clickable prototype. We help shape what to build before a line of code is written.
How we work
Software is a system, not a screen.
Small by design
No account managers, no handoffs. The people who plan the work are the people who do the work.
End to end
Strategy, design, and engineering from the same heads — so the product holds together from the database to the pixels.
Built to be kept
Minimal dependencies, readable code, boring infrastructure. We build software you can still maintain in five years.
