Inside the app

Stop guessing which strike to sell.

Everything an options seller needs to pick safer contracts and keep an eye on them, in one iPhone app.

Real odds for every strike.

Pick a stock and an expiration and see each strike's chance of expiring worthless, estimated from live market data. Weigh the premium against the risk before you sell, not after.

  • Calls and puts for every listed expiration
  • Premium and distance to strike next to every probability
  • Browse the market, crypto ETFs and top premiums
Option chain with a probability ring for every strike

Alerts

Know when to roll, before it's too late.

Strike Price watches every open contract. When a position's probability drops, you get a push notification, so you can decide whether to roll or close while you still have options.

  • Push alerts when the odds change
  • High-premium alerts for the stocks you watch
  • Live Activities for the positions you care about
