Verdict
The clearest difference is price: Ready! Action at Free against Light Meter Wheel's $1.99. Ready! Action also leads on update cadence (weekly vs every 2 months). Light Meter Wheel's advantage is chart position (#188 vs unranked) and iOS requirement (15.6 vs 17.0). On ads, in-app purchases and device support there is nothing between them.
