Verdict
The clearest difference is price: Phaos at Free against myLightMeter PRO's $4.99. Phaos also leads on rating (5.0 vs 4.8). myLightMeter PRO's advantage is ratings volume (1.1K vs 4) and chart position (#16 vs unranked). On update cadence, ads, in-app purchases and device support there is nothing between them.
