Verdict
The clearest difference is in-app purchases: Chronodev at none against Crown & Flint's 1. Chronodev also leads on review sentiment (100% vs 88%). Crown & Flint's advantage is update cadence (every 9 days vs monthly) and rating (4.7 vs 4.5). On price, ads and device support there is nothing between them.

Both are free to download. Crown & Flint sells 1 one-off in-app purchase. Chronodev asks for nothing beyond the download.
Crown & Flint holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Crown & Flint has 16 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 88% of Crown & Flint's written reviews are positive against 100% of Chronodev's, so the app with the better star average is not the one people write more warmly about.
Crown & Flint ships an update every 9 days, Chronodev monthly. The most recent releases landed on October 16, 2026 and September 29, 2026 respectively.
