9 answers · auto-generated from this app's public dataHow much does Prions make per month?▾
Based on our ML-calibrated revenue forecast, Prions earns approximately $200/mo. This is a US-storefront-equivalent estimate; global revenue can be several times larger for internationally-distributed apps. See the methodology page for the full formula and confidence bands.
Is Prions profitable?▾

Estimated audience: ~30K lifetime downloads, ~850 monthly active users, and ~170 daily active users. Derived from ratings count × category installs-per-rating × age decay. US-storefront-equivalent — global audience can be 5-10× larger for internationally-distributed apps.
