Business and product

FingerPick is a consumer mobile app

What we offer

FingerPick is a multi-touch utility for random selection, quick team splitting, and turn ordering. It is designed for gatherings, games, activities, and everyday coordination, with core selection processing on the device.

FingerPick is free to start. Revenue comes from optional subscriptions and optional in-app purchases. The app does not display advertising, and we do not sell participant information, touch positions, or local selection results.

Official distribution

FingerPick is distributed only through its official Apple App Store and Google Play product listings.

Google Ads API use case
