Proof of Usefulness Score
You're In Business

Trall is a legitimate, award-winning digital songbook application in Norway developed with OsloMet and Bakken & Baeck. While the submission itself was of very low quality (containing false claims of 'most people' using it and an incorrect business type of 'stage setup'), external verification confirms it is an active EdTech product with approximately 8,500 users, daily active usage in Oslo schools, and recognized cultural value. The score reflects its proven utility and high build quality, heavily penalized for its small current scale (<50k users) and the poor quality of the submission data.
