Flow Greeks is the ultimate and essential tool for any trader! The app serves retail traders to analyze opportunities pursued by institutions with significant capital allocation. Mastering the skill of reading options flow will enable you to navigate the complexities of institutional order flow data with precision, providing valuable insights for your trading decisions. Real Time Option Flow: ------------------------------------- We display the options flows for all stocks and ETFs in real time as they occur. The flow can be a SWEEP or BLOCK. SWEEP: Sweeps represent aggressive orders executed across several exchanges and are more likely to be a directional bet on the underlying stock. A Sweep usually signals urgency, indicating that the trader anticipates a rapid price movement in their favor. BLOCK: Block trades involve privately negotiated orders that occur off-exchange. For BLOCK trades, we lack the certainty to state the intention behind the trade due to it being privately negotiated. Trade-worthy Alerts: -------------------------------- Our smart algos continuously scan all the flows every minute to identify powerful trade-worthy alerts and send you push notifications in real time. On-Demand Historical Flow Data: ----------------------------------------------------- Retrieve historical flow data for any ticker or contract using the specified filters, covering up to the last 30 days. Flow Screener with Advanced Filters: ----------------------------------------------------------- Filter the LiveFlows and Historical flows as you need. You can filter by Calls, Puts, Premium amount, Sweeps, Blocks, Ask side, Bid side, and many more. Spot the Unusual Options Activity: ------------------------------------------------------- A SWEEP or BLOCK is deemed Unusual when the Volume of the trade exceeds the Open Interest. An Unusual flow is indicated by a YELLOW border on the SWP or BLK. Most Bullish / Bearish Leaderboard: ----------------------------------------------------------- Find the most bullish and most bearish stocks daily based on the difference in premium between bullish vs bearish bets. It serves as an excellent starting point to identify stocks showing strong bullish or bearish tendencies for the day. By clicking on any symbol, you can view the detailed individual flows executed for that particular stock. Paid subscription is required to access all the features.

Verdict

The call

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 (#181 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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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