How much does Slowly make per month?

Based on our ML-calibrated revenue forecast, Slowly earns approximately $5.0K/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 Slowly profitable?

With estimated build cost $145K and monthly revenue $5.0K, Slowly looks break-even-grade — payback period sits around 2.4 years. Profitability also depends on paid-acquisition spend and refund rate which the public model doesn't see.

How many users does Slowly have?

Estimated audience: ~13.0M lifetime downloads, ~1.0M monthly active users, and ~200K 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.
