## Most critical reviews (8 lowest-rated)

### 1/5 — Not working!

*2023-05-28*

Purchased the app in 2021 and enjoyed the analysis however the app stopped working in realtime. Now the app fails to even run.

### 1/5 — Don’t waste your time

*2020-03-26, version 1.3.5*

This app repaints signals just like most other garbage signal providers. If the signal is wrong, it magically disappears like it never happened.

### 1/5 — Crashes..

*2015-02-01, version 1.0.3*

Can't seem to get it to work.  At all. Non functioning.

### 4/5 — BETTER TRADING

*2015-11-10, version 1.0.7*

I had heard about the Kalman  filter (a fancy moving average) from electronics experience, but when I emailed Igor about the Heiken Ashi trend indicating technique he immediately incorporated it into the app and I had to buy the app.  It gives very good signals in the weekly bar mode if you are doing more casual trading.  Also, the Laguerre algorythm if tuned right can give very near the same signals Heiken Ashi.  In the custom signal a 5 and 34 simple moving average will, I heard, give an Elliot wave type response.

### 4/5 — Purchased

*2014-11-25, version 1.0.2*

Thanks for upgrade/bug fix, Igor.  I have now purchased app.

### 5/5 — The Tool Every Trader Needs!

*2018-12-06, version 1.3.4*

This app is great! It can draw almost every trend line for you instantly! It can save you so much time! There is no other app that has the settings and abilities like this app has. These tools are some of the most powerful that I have seen on any other app!
I really wish that the resolution was updated for the iPhone X and newer iPhones, but this app is still the app you need to become successful!

### 5/5 — Excellent app

*2015-03-10, version 1.0.4*

Thanks for making excellent app with highly accurate signal blow my mind away,I am doing trading for 15 years but this app will give you real stock. Buy and sell signal,highly recommended and thanks for developer to make this happen

### 5/5 — One of the BEST forecasters I have ever seen

*2014-11-17, version 1.0*

Igor-

You continue the trend of being one of the best mathemeticians and forecasters of the market out there.

It is amazing to me that, as an individual,  you seem to outperform the large multi-nationals.  Makes me glad you are on "our side" and not a hacker, given your extraordinary skills !!!

Thank you for this addition to your portfolio of solutions.  I look forward to using it productively.

I also hope that things stabilize in the Ukrain and life become less uncertain !!!
