Fantastic App
“...this app gives me “buy” and “sell” signals that make it so EASY... I’m not a day-trader, I just want to know when to be in the market and when to bail before the hammer comes down! If you follow the buy and sell signals, you will get all of the gains when a stock or mutual fund goes up and none of the losses when it goes down. This app is easy-to-read, easy-to-understand and it will keep you from holding on to a fund in those ugly downturns. Buy this app!”
- Porter

Super app
“Developer keeps making an already great app, better and better. This trend following app is highly accurate. Just super, enough said.”
- Brainal

### 5/5 — EXCELLENT!

*2023-05-13*

I’ve used this off and on since 2014 both personally and professionally and have always found it useful in conjunction with more complicated trading apps.  Glad to see it back, Igor!

### 5/5 — Still one of the best app for trend trading

*2020-05-29, version 2.8.10*

Thank you Igor, for making this app work again. It’s been my favorite app for viewing a trend since you developed it years ago.

### 5/5 — Love it

*2019-03-18, version 2.8.6*

Thank you for helping average traders improve ... I can’t wait to see future upgrades. But some of the charts for say like ( Barrick Gold) are messed up.. even BTC and crypto currencies charts are not functioning .. please fix and thank you so much again

### 3/5 — Working again on iPad Air

*2018-03-29, version 2.8.2*

Seems they got it working again after a long time off.

### 1/5 — Scam!!!!

*2016-03-24, version 2.4.8*

Watch these guys,they manipulate the buy,sell signals constantly.. If it goes in there favor it stays up ,if not it's gone ...very deceptive! (Notice other reviews stating this)Their support people are extremely, extremely hard to understand,and will not respond unless you email them numerous times .very disappointed!!

### 5/5 — Had to reload program but now crashes

*2015-09-20, version 2.4.2*

Had to reload program but when I tried to restore
the super signal add on it crashed and now won't reload at all

### 2/5 — Needs bug fixes

*2015-03-27, version 2.3.9*

I love this app but it has had bugs for several weeks that prevents user from customizing settings. Will add more stars when the app is fully functional again.

### 3/5 — New update crashes after settings menu

*2015-03-02, version 2.3.9*

Great features but after update has a bug.

### 4/5 — Creative approach to trend spotting

*2014-07-26, version 2.2.8*

This app lets you use sophisticated mathematical tools to better understand when changes in stock price direction occur.  It provides alert markers, many standard and non-standard mathematical operations.  It makes it easy for the more expert user to parameterize functions and provides sensible defaults for the non-expert. I learn something new every time I use it.

### 4/5 — Pretty Good

*2014-04-18, version 2.2.5*

Surprisingly the technical analysis tools provided by this app are pretty good. Don't let the crude user interface turn you off. Apparently the creators of this app are better mathematicians than IOS programmers. For example in the symbol entry window, spell check feature is not disabled. This issue should be pretty simple to fix. Also the latest update has rendered the iPhone version pretty much useless, so I cannot recommend the current version for the iPhone. All that being said this is a pretty useful iPad app. The charts look great and the signals are pretty useful. Another great feature of the app is that you can create watch lists and scan all the symbols in the watch list with one click. There are some extra paid features that sound intriguing. I have not tried them yet.
