We build small apps that actually help.

Teoremas is an indie software studio from Portugal. We ship focused mobile apps for people preparing for something — an exam, a trip, or a Saturday night.

How we think about software

Built by one person in Portugal. Four principles that keep the work small and honest.

Buy onceNo monthly subscriptions for tools you should own. One-time purchase, lifetime access, no dark patterns.
Explain the whyThe interesting part isn't the answer — it's the rule behind it. Our apps teach, not just test.
Respect attentionNo ads, even in free tiers. Minimal notifications. Your time is for the task, not the app.
Ship from PortugalSmall studio, European data residency, privacy-first by default. Written by someone who reads every support email.
