# OptionStrat vs Sigma Trade

The clearest difference is monetization model: Sigma Trade at free against OptionStrat's free with in-app purchases. Sigma Trade also leads on review sentiment (100% vs 80%). OptionStrat's advantage is ratings volume (1.9K vs 47) and chart position (#78 vs unranked). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. OptionStrat sells 12 in-app purchases, starting at $19.99 per month and Sigma Trade sells 2 in-app purchases, starting at $39.99 per month. Whichever you choose, the download price is not the number that matters.

Sigma Trade holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: OptionStrat has 1.9K ratings behind it against 47, so its average is the more settled of the two. Written reviews point the same way: 80% of OptionStrat's written reviews are positive against 100% of Sigma Trade's.

OptionStrat ships an update every 10 days, Sigma Trade weekly. The most recent releases landed on October 29, 2026 and October 24, 2026 respectively.
