Verdict
The clearest difference is price: Materrium at Free against Starfall Numbers's $4.99. Materrium also leads on update cadence (every 2 months vs every 11 months). Starfall Numbers's advantage is ads (none vs shown) and chart position (#150 vs unranked). On in-app purchases and device support there is nothing between them.
