A quiz studio · by RunRiva
Beautifully made trivia,
one obsession at a time.
We build deep, single-subject quiz apps for iPhone and Android — each one focused on a topic worth knowing well. Source-attributed questions, a daily challenge, friends and leaderboards, and an ad-free option. No clutter, no nonsense.

Each app is its own world — same care, different obsession.
The studio
Made by one person, with care
RunRiva is an independent studio. Every question is drawn from open, source-attributed knowledge — and every app is built to be played every day, not to chase your attention.
