Verdict
The clearest difference is price: Graflex Light Meter at Free against Massive Dev Chart Timer's $9.99. Graflex Light Meter also leads on rating (4.5 vs 3.7) and update cadence (every 4 days vs every 5 months). Massive Dev Chart Timer's advantage is ratings volume (54 vs 2) and chart position (#22 vs unranked). On ads, in-app purchases and device support there is nothing between them.
