# PV vs Power

PV and Power are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

PV ships an update every 4 days, Power every 5 days. Both last shipped on September 24, 2026.
