Verdict
The clearest difference is ratings volume: Calendars at 122K against Solid Calendar's 119. Calendars also leads on monetization model (free with in-app purchases vs paid) and chart position (#103 vs unranked). Solid Calendar's advantage is review sentiment (79% vs 55%) and rating (4.9 vs 4.7). On price, update cadence, ads and in-app purchases there is nothing between them.
