We build iOS apps
and software that ships.
QuantumBytes is a Canadian software studio. We design, build, and launch iOS and mobile apps, and partner with teams on custom web and backend work — from first prototype to App Store release.
Focused services, end to end.
A small studio with senior engineers — you work directly with the people building your product, no handoffs.
iOS & mobile apps
Native Swift / SwiftUI apps for iPhone and iPad — designed, built, and shipped to the App Store. We handle TestFlight, review, and post-launch updates.
Custom software
Web apps, internal tools, APIs, and integrations. Modern stacks (TypeScript, Node, Postgres) and pragmatic delivery — small batches, real users, fast feedback.
Product & technical advisory
Architecture reviews, scoping, technical due diligence, and fractional CTO support for founders and product teams who need a senior perspective.
Senior engineering, no overhead.
QuantumBytes was founded to give clients a direct line to senior software engineers — without the layers of a traditional agency. We pick a small number of projects and ship them well.
We work with founders, growing teams, and established companies who care about craft. Most engagements run 4–12 weeks, with options for ongoing support after launch.
