H2H is built by one person, but not out of thin air. Some of the sounds you hear in the app were recorded and shared by other people, who deserve the credit for them.
Several of H2H's alert sounds are built from recordings shared by their authors on freesound.org:
Each recording was shortened and re-encoded for use as a notification sound. The scoreboard buzzer and the app's spoken lines are generated with ElevenLabs.
Game schedules, scores and point spreads come from a licensed sports-data feed. H2H is not affiliated with, endorsed by, or sponsored by any sports league, team or broadcaster.
