Verdict
Quant Data and Tradier both sit at 4.5 stars, but that hides the real split: 80% of Quant Data's written reviews are positive against 15% of Tradier's. Quant Data also leads on iOS requirement (16.4 vs 18.0). Tradier's advantage is in-app purchases (none vs 4) and ratings volume (658 vs 43). On price, rating, 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. Quant Data sells 4 in-app purchases, starting at $74.99 per month. Tradier asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.5 for Quant Data against 4.5 for Tradier. That said, the two scores are not equally well evidenced: Tradier has 658 ratings behind it against 43, so its average is the more settled of the two. Written reviews are what separate them: 80% of Quant Data's written reviews are positive against 15% of Tradier's.
Both ship on a similar rhythm, roughly every 3 weeks. Both last shipped on November 14, 2026.
