Portfolio Armor helps you hedge your stocks and ETFs by showing you the optimal put options to give you the precise level of protection you want at the lowest cost. The capability to scan for optimal collars, which can lower the cost of hedging further, is available as an in-app subscription. A current list of Portfolio Armor's top names, which tend to beat the market most of the time, is available as another in-app subscription. How it works: You enter your US-traded stock or ETF position, and the maximum downside risk you are willing to accept for it (your "threshold"). Portfolio Armor then uses its proprietary algorithm to instantly scan and analyze all of the available put option contracts for the stock or ETF, searching for the optimal put option contracts to most economically hedge the position. About Portfolio Armor’s proprietary algorithm: Portfolio Armor’s algorithm was developed in conjunction with a postdoctoral fellow in the financial engineering department at Princeton University. It is model-independent and does not rely on any parametric assumptions, so there is no chance of model error. In some cases, the cost of protection may be higher than the loss you are looking to prevent. In those cases, Portfolio Armor will inform you that no optimal options are available. Two in-app subscriptions are available: 1) Optimal Collars (auto-renewable) - Access to the Optimal Collar feature for $9.99 per month. Cancel anytime. * 2) Top Names (auto-renewable) - Access to Portfolio Armor's daily Top Ten List for $29.99 per month. Cancel anytime. * Praise for Portfolio Armor: "For a stock or ETF investor who wants to buy insurance against a loss greater than a set percentage, this clever program scans the matrix of striking prices and expirations to identify the most economical put option to accomplish the task. Choosing from the many alternatives can be a complicated task; this program makes it quick and easy." -- Dr. Robert A. Strong, CFA, Professor of Finance, University of Maine "Navigating derivatives markets can be daunting for many investors and so the benefits of hedging have usually been limited to professionals. Portfolio Armor is an innovative system that effectively identifies the lowest cost options for affordable hedging solutions. This tool is invaluable for investors who wish to protect their wealth against market drops." -- Dr. Ren-Raw Chen, Professor of Finance, Fordham University "In today's market environment, investors are increasingly concerned about downside risk. Portfolio Armor has been an effective tool in helping me protect my clients' portfolios." -- Greg Clifton, Chartered Financial Consultant, Certified Financial Planner "Portfolio Armor is exactly what I need to give me some confidence that I’m buying the right puts. (It’s real money after all) It’s so hard for a beginner like me to feel like I have all the numbers right." -- Richard Carver, private investor "I love that you invented a friendly tool that an options novice can use! Also, I love that your calculations are kept in the background (with no visible Greeks, break-even graphs, or lingo, and minimal, simple customer input)!" -- Tom Patane, private Investor * Your payment will be charged to your iTunes account at confirmation of purchase.

OPTIONS PROFIT CALCULATOR: Find and edit option strategies in real-time with our options profit calculator to gain a visual understanding of your trades. OptionStrat's strategy visualizer is used to find the potential profit and loss at various prices, as well as show how your trade is affected by implied volatility, time decay, and other factors. The strategy visualizer makes it easy to scroll through various strikes and expirations to build an options strategy. Nearly any strategy can be created, including strategies with underlying stocks like covered calls, or multiple expirations such as double diagonals. Over 50 strategy templates are available to choose from, each with a handy setup chart and description. STRATEGY OPTIMIZER: Automatically calculate the best strategies given a target price and expiration date. The options optimizer will search through thousands of potential trades to find which strategies maximize returns or chance of profit (or somewhere in between). UNUSUAL OPTIONS FLOW: OptionStrat Flow scans the market to uncover large and unusual trades as they happen, giving you insight into trades by institutions and other smart money. Not only do we show large call or put purchases, but we detect if the transaction showed urgency or aggression from the buyer or seller to show you both sides of the market. We are the first to provide unusual options activity for complex strategy types. OptionStrat Flow detects spreads, condors, and other advanced strategies and categorizes them as bearish, bullish, neutral, or directional.

Verdict

The call

The clearest difference is price: OptionStrat at Free against Portfolio Armor's $89.99. OptionStrat also leads on update cadence (every 10 days vs every 4 months) and rating (4.8 vs 4.4). Portfolio Armor's advantage is review sentiment (90% vs 80%) and iOS requirement (11.0 vs 14.0). On ads, in-app purchases, monetization model and device support there is nothing between them.

OptionStrat is free to download; Portfolio Armor costs $89.99 up front. Portfolio Armor sells 3 in-app purchases, starting at $2.99 per month and OptionStrat sells 12 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

OptionStrat holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: OptionStrat has 1.9K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 90% of Portfolio Armor's written reviews are positive against 80% of OptionStrat's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Portfolio Armor ships an update every 4 months, OptionStrat every 10 days. The most recent releases landed on October 29, 2026 and October 27, 2026 respectively.
