How much does Grotu make per month?

Based on our ML-calibrated revenue forecast, Grotu earns approximately $500/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.

With estimated build cost $205K and monthly revenue $500, Grotu looks well below break-even — current monthly revenue is much smaller than the estimated build cost. Profitability also depends on paid-acquisition spend and refund rate which the public model doesn't see.

How many users does Grotu have?

Estimated audience: ~7K lifetime downloads, ~1K monthly active users, and ~600 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.
