*MRR is a modeled point estimate, never a measured figure: computed from grossing rank, ratings momentum, paid-chart position and verified anchors, recalibrated weekly, with our measured error published on the methodology page. The full modeled range sits behind every number (hover it, or open the app's estimator breakdown). Apps without enough signal show no number at all.
