Thanks. ### 5/5 — Works great! *2012-03-22, version 1.0* Great calculator! I love the Fixed Fractional Position Sizing one. Thanks. ### 5/5 — Awesome! *2012-03-20, version 1.0* Surprisingly useful, nicely organized. Must have trading tool. ## Most critical reviews (10 lowest-rated) ### 1/5 — Poor design *2015-10-09, version 2.3.9* Regardless all efforts in this app I can't give it more than one star due to the poor design especially that it looks stretched on iPad besides that, it does not support landscape mode. ### 1/5 — Useless *2012-12-20, version 1.0* Useless for futures. ### 1/5 — Waste *2012-06-07, version 1.0* Of time. Looks like it was built as a showcase app for a development business. No real purpose or value. ### 2/5 — Very usefull *2013-09-19, version 1.1* Exactly what I was looking for. Great app, but needs iPad support. It works on an iPad, but the size is designed for an iPhone. Also, it would be very useful to have a pyramiding calculation. ### 2/5 — It's ok *2013-07-14, version 1.1* It does some simple calculations that can be somewhat useful in trading ### 2/5 — Mediocre *2012-09-20, version 1.0* Lots of calcs but they're fairly cryptic; the help is accessible and seemingly abundant and yet murky. ### 3/5 — Would be great *2019-03-27, version 2.3.9* The developers would have a great app if not for the bugs . I have no problem purchasing if only app would not freeze. ### 3/5 — Experation? *2017-01-11, version 2.3.9* The app is ok.... They should know that options expire or have an Expiration date... They don't have an Experation Date...Come On Man... Use Spellcheck! ### 4/5 — Good tool for position sizing *2013-10-12, version 1.1* I use this tool for position sizing using atrs ### 4/5 — Useful app *2013-02-05, version 1.1* I use this app pretty much every time I make a trade for position sizing and risk management. I have an Excel spreadsheet that does the same thing but usually I use this app instead. There is an issue with the Fixed fractional position risk calculator. If you have a very low risk trade it will calculate a buy value greater than your portfolio value field. If that happens you can just lower the Risk % field to limit the size of the trade. ## Most praised reviews (10 highest-rated) ### 5/5 — Traders Friend *2020-07-18, version 2.3.9* An extremely helpful and useful app, well done! **Developer response:** Thank you ### 5/5 — @stockwatch1 *2019-12-23, version 2.3.9* This is a great calculator with a lot of advanced calculators, but I personally use it everyday to check my risk-reward on every trade! ### 5/5 — Great app! *2016-08-28, version 2.3.9* Exactly what I needed, simple, fast and no need to fire up any computers or mess with spreadsheets. The app does what it says it should do. I use it on my ipad and have no complaints. If you need a convenient risk calculator for your trading, I can recommend this app. Thanks. ### 5/5 — Good use *2015-03-22, version 2.2* This app is very useful. ### 5/5 — Good app *2014-08-25, version 1.1* Great for sizing and controlling risk. ### 5/5 — Awesome app *2013-03-30, version 1.1* Excellent tool, every investor must have this app. ### 5/5 — Nice tool *2012-08-25, version 1.0* Save a lot of time.

Thanks. ### 5/5 — Really useful for trading... *2012-05-10, version 1.0* Sometimes after hitting the done button the number pad doesn't go away which is a little bug but other than that it's an awesome app. I use the fixed fractional method before every trade now. Highly recommended for position sizing... --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/). User reviews are verbatim App Store reviews.
