# Quant Data vs Flow Greeks

The clearest difference is review sentiment: Quant Data at 80% against Flow Greeks's 31%. Quant Data also leads on ads (none vs shown). Flow Greeks's advantage is rating (4.7 vs 4.5) and chart position (#194 vs unranked). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Quant Data sells 4 in-app purchases, starting at $74.99 per month and Flow Greeks sells 2 in-app purchases, starting at $29.99 per month. Whichever you choose, the download price is not the number that matters.

Flow Greeks holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Flow Greeks has 264 ratings behind it against 43, so its average is the more settled of the two. Written reviews complicate that: 80% of Quant Data's written reviews are positive against 31% of Flow Greeks's, so the app with the better star average is not the one people write more warmly about.

Quant Data ships an update every 3 weeks, Flow Greeks fortnightly. Both last shipped on October 2, 2026.
