Have an app built, iOS and Android from one line
An app in the store. Expo and React Native when that fits the job. Own listings: Red Flags, Dirty Seconds, StepQuests.
Red Flags is a multiplayer party game, lobby to a round in under two minutes as a product goal. Dirty Seconds is the offline 30 Seconds style game, start a round in under a minute. StepQuests is web plus mobile, with Haarlem Uitjes as a local tour.
A listing check on this site pulls public App Store data. For Play you paste title and description if the store does not load. The mobile service page says what a job includes. Looking for Haarlem specifically? That variant lives under Haarlem.

Have an app built
- Do you write native Swift and Kotlin?
- When that is a hard requirement, yes. The party games and StepQuests run on Expo. Native when a library or a store rule forces it.
- Do you help with the listing?
- Yes. The listing check on this site is that kind of review. Screenshots, title, description. No ranking promise.
- Do I need to live in Haarlem for updates?
- No. Video is enough. Updates go through TestFlight or Play internal testing.
