Verdict
The clearest difference is price: Viddy at Free against Massive Dev Chart Timer's $9.99. Viddy also leads on update cadence (every 2 days vs every 5 months). Massive Dev Chart Timer's advantage is in-app purchases (none vs 2) and chart position (#30 vs unranked). On ads there is nothing between them.
