Verdict
The clearest difference is price: Develop! Film Timer at Free against Massive Dev Chart Timer's $9.99. Develop! Film Timer also leads on rating (4.8 vs 3.7) and update cadence (every 4 weeks vs every 5 months). Massive Dev Chart Timer's advantage is chart position (#64 vs unranked) and iOS requirement (15.6 vs 17.0). On ads, in-app purchases and device support there is nothing between them.
