Verdict
The clearest difference is rating: TradeFlags at 5.0 against DataMelon PRO's 4.5. TradeFlags also leads on in-app purchases (none vs 2). DataMelon PRO's advantage is update cadence (monthly vs every 2 months) and ratings volume (36 vs 5). On price, ads and device support 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. DataMelon PRO sells 2 in-app purchases, starting at $0.99 per month. TradeFlags asks for nothing beyond the download.
TradeFlags holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: DataMelon PRO has 36 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 76% of DataMelon PRO's written reviews are positive against 67% of TradeFlags's, so the app with the better star average is not the one people write more warmly about.
DataMelon PRO ships an update monthly, TradeFlags every 2 months. The most recent releases landed on October 5, 2026 and October 13, 2026 respectively.
