Verdict
The clearest difference is price: Delta at Free against Pichon's $4.99. Delta also leads on update cadence (every 4 weeks vs every 22 months) and chart position (#110 vs unranked). Pichon's advantage is in-app purchases (none vs 3) and iOS requirement (10.0 vs 14.0). On ads and device support there is nothing between them.
