Verdict
The clearest difference is rating: Solid Calendar at 4.9 against DueOver's 3.0. Solid Calendar also leads on ratings volume (119 vs 1) and device support (3 vs 1). DueOver's advantage is review sentiment (100% vs 79%) and update cadence (weekly vs fortnightly). On price, ads, in-app purchases and iOS requirement there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Solid Calendar sells 2 one-off in-app purchases and DueOver sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
Solid Calendar holds the better App Store score, 4.9 against 3.0. That said, the two scores are not equally well evidenced: Solid Calendar has 119 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 79% of Solid Calendar's written reviews are positive against 100% of DueOver's, so the app with the better star average is not the one people write more warmly about.
Solid Calendar ships an update fortnightly, DueOver weekly. The most recent releases landed on September 23, 2026 and September 17, 2026 respectively.
