# ScaleGen vs PhaseII

The clearest difference is update cadence: PhaseII at every 9 days against ScaleGen's every 29 months. PhaseII also leads on review sentiment (100% vs 71%) and rating (5.0 vs 4.7). ScaleGen's advantage is ratings volume (12 vs 2) and iOS requirement (10.0 vs 12.0). On ads, in-app purchases and monetization model there is nothing between them.

ScaleGen costs $3.99 and PhaseII $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
