TSN Studio
Independent app developer building thoughtful apps and games for everyday people. Based in Canada.
What We Build
TSN Studio is a one-person indie studio focused on making apps that are genuinely useful and games that are actually relaxing. Every product is built with care: no dark patterns, no forced ads, no unnecessary friction.
The studio started with a practical problem — finding good citizenship test prep tools for Canada — and grew into a broader mission to build software that respects the people using it.

How We Build
No dark patterns
No fake timers, no forced sign-ups, no artificially hard levels designed to sell hints.

Core features are always free. Paid upgrades exist only where they add genuine value.
