Verdict
The clearest difference is rating: DoodleConnect at 4.7 against Delta's 3.1. DoodleConnect also leads on in-app purchases (none vs 3) and ratings volume (56 vs 7). Delta's advantage is review sentiment (67% vs 56%) and device support (4 vs 2). On price, update cadence and ads 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. Delta sells 3 one-off in-app purchases. DoodleConnect asks for nothing beyond the download.
DoodleConnect holds the better App Store score, 4.7 against 3.1. That said, the two scores are not equally well evidenced: DoodleConnect has 56 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 56% of DoodleConnect's written reviews are positive against 67% of Delta's, so the app with the better star average is not the one people write more warmly about.
DoodleConnect ships an update every 2 months, Delta monthly. The most recent releases landed on September 21, 2026 and August 19, 2026 respectively.
