When it comes to support, it is unusually amazing to deal with developers who communicate in such a clear and thorough manner. As for the APIs, they are some of the cleanest and most intuitive I have ever used. The header files are commented in a clear and meaningful way, the HTML documentation provides a nice reference and the sample projects are more than enough to have you adding charts to your project in a matter of minutes. The feature set is incredibly rich and you can tell that a lot of thought was given to the overall architecture; coding against it feels like it came straight out of Cupertino. Thanks and keep up the GREAT work!!

Adding the ability to graph patient data was the essential next step in the further development of my neonatal intensive care App.  ShinobiControl's elegant API, combined with extremely clear documentation and examples enabled me to add a serum bilirubin treatment threshold graph for neonatal jaundice in just under 7 hours from download to completion.  The quality of the graphs produced far outshines my previous efforts with Core Plot or other APIs, and has enabled me to quickly move onto other areas of my App.

I simply cannot recommend ShinobiControls enough!

You might be interested to know that the process until we have bought charting components has been a long sell to a client - we started with a budget option of some free open source Javascript charting in a web view about 18months ago, and he was never totally happy. But now he's given the OK to get something good and include some good charting software, and really, your ShinobiControls software is the only game in town :-)

The thing about  @shinobicontrols GPU-based graphs is that you dont appreciate how amazing they are, until you see them live.

ShinobiCharts is everything you would expect from a modern framework, with good documentation, well structured relationships and classes, customisable interface elements, and the datasource and delegate callbacks you would expect.

We found that the price tag from ShinobiControls was worth it to receive the customisation we wanted, the documentation we needed and the best ongoing support.

We made a detailed market analysis to identify the most effective solution for our problem. The problem was to find right a native charting framework for iOS with features like well-documented intuitive API, easy design customization, high abstraction and efficiency in solving problems and many varieties of charts. Then we found Shinobicharts, tried a trial version and the result was a stunning reporting tool with amazing chart designs, animations leveraging memorable gesture-based user experience following Apple human interaction guidelines. Support was outstanding, even when we were still using just the trial version. The team behind Shinobicontrols are continuously adding new features, so with every new version we are still amazed how we can use these features to bring our customers a new level of user experience.

Just wanted you to know that I bought the Charts product yesterday and I've been looking for something like this for over a year - this is exactly what I've needed...Thanks for a great, well-documented product.

If displaying charts of many varieties is a core functionality of your App, there is currently no better plug-in solution than ShinobiCharts. You can't make up the amount of money it saves you by saving immense amounts of time! Did I say that their support and attitude is just awesome? I've thrown a lot of questions at them, and got honest, no-fuss answers to each one of them even when I was still a trial user. I can't help but name ShinobiCharts the best and most useful chart drawing, awe-inspiring, insanely great thing that money can buy.

ShinobiCharts is a well designed API for charts, easy to use and the results are stunning. It saves us a lot of time and last but not least, ShinobiCharts support is outstanding.

This API should be in the toolkit of every serious app developer. The extensibility, and features for a first release are outstanding. Creating charts that look this good used to be a lot of work and now they can just be dropped into an app in record time, leaving us to focus on the core functionality.

By far the best 3rd party API I've ever used. With an incredible level of polish and attention to detail, ShinobiCharts is so easy to use that it feels like it's part of the iOS SDK.

VERY impressed with #shinobicontrols charting for iOS! Check 'em out. I'm about to buy my full license right NOW! #esri #iOS

Trying ShinobiGrids from @shinobicontrols - easy to use and customise, and an ideal counterpart to their excellent iOS Charts controls.

Been looking for a grid system like #ShinobiGrids by  @shinobicontrols for ages! Simple API & great performance on all of my iOS devices too.

It makes creating table layouts simple! I love extensibility & the custom cells. Going to save hours on my next project. Really impressed!
