Top Mobile App Development Companies in Chicago

We hired Dedicated Developers to help us build and design both hardware GPS sensors used in the transportation industry as well as the web application and mobile apps to monitor the sensors. The sensors connect the transportation sector to the Internet of Things (IoT). It was challenging to find developers that had the complete package of skills we needed for this project. Lots of companies had the software skills, but not very many had the hardware skills. We were thrilled when we found Dedicated Developers, because they were able to do both the hardware and software designing for us. The hardware they created are sensors used to monitor a wide variety of things for the transport industry. The sensors can monitor speed, acceleration, elevation, breakdown, GPS route coordinates, and then transmit all the data through the cellular network. Our clients can then see all the data points within the centralized application control panel to fully monitor their cargo. They did a lot of initial research and were able to suggest hardware components and sensors that would be the best configurations that would reduce the costs during mass production. They helped us figure out the best components that are reliable, durable and cost effective, so the total hard costs for each finished sensor goes down, and profits go up. They were able to bring the total cost of each unit down by 21%. They were creative while building the prototype sensors, which they were able to do quickly within a couple months. The software they created to run and monitor the sensors uses the latest cutting-edge technology, and connects our industry to the Internet of Things, which is fast, efficient, responsive and very well designed. The hardware sensors they created for us are top notch, and the monitoring software to run and monitor them has been very well received by our clients. It’s been able to make our company a cutting edge leader in our industry.

We are completely satisfied with the engagement and project output. We have decided to work with rSTAR on all our future projects. We will definitely endorse and refer them for anybody with similar requirements.

Saritasa is our preferred vendor for project development, on web-based and desktop applications, to active and inactive clients in a wide range of vertical industries. Selecting preferred partners/vendors takes hours of evaluation and analysis of multiple parameters such as technology capabilities, the management team and leadership, the skills set, personal connections, organizational culture, response time and customer service attitude, physical office look, layout and neatness, pricing and a history of success.

I don’t even know where to begin to describe the experience I have had with this company. I came to them after already being treated so recklessly by another company. That company charged me $100,000 and never delivered a product that was worth a dollar. I had high hopes for this company as they seemed compassionate and empathetic toward my plight, making many promises that were never kept. They were given code to review to give me a price window so I could make an educated decision if I could afford to move forward after the loss I already suffered. I was reassured that if for some reason we got anywhere near the top of my estimate window I would be notified and we would have meetings about how to move forward. Not only was I not notified the communication process during the whole project was awful. The backend system that they promoted as what sets them apart from other companies was never used even though the CEO claim several times it was. What was supposed to cost a certain amount of money and only take three months has now been eight months I have paid the top of my budget for a project that was not completed because they continue to want to tell me it would be more. They took it upon themselves to completely change the project without notifying or disclosing that to me. Then when I have expressed my frustration over cost and time delay all of which was never explained to me till the 7 month I am met with condescending attitude’s where I am not spoken to not like a client but rather a employee who doesn’t understand what’s going on. Several times I remind them what they promised and prices they gave by sharing the emails to show that I am not making things up but their stance is they don’t care because they felt they had delivered more than what I deserved even though it was for things I did not ask for and was not aware of. They spent the time and money doing things that were not to my knowledge so that then there was no time or money left to do what I had asked for to begin with. I still ended up paying the complete balance that was due even though $28,000 even though I did not get the project completed per the terms that was agreed-upon through many emails, discussions and design and still 72 hours later the CEO will not release my code to me and will not release my passwords and accounts that were created by the developers on my companies behalf. In the beginning they told me they would hold my hand and make this foreign process comfortable for me and instead now talk down to me and treat me like I was a naïve fool to even try to venture into this without background. They boast that they have had 200% growth in the last year and a half and that is because they are focused on quantity and not quality interaction for their current clients. They sub all of their work out to India and those involved in the United States office have very little involvement with your project. I now have to hire a second attorney to deal with this unethical company that although got their money still won’t give me what is legally mine. They will sell you with their bells and whistle’s during the sales process but the moment you execute the contract and make your first payment you just become another account to be collected on. The worst part is I still paid just so I could move on and not have to fight or hire another attorney but they still won’t give me my accounts or code and refuse to fully communicate back to my requests. I don’t recommend this company.

Highly experienced agency. Great example in investing in quality people with expert skill sets.

Simply iCard have worked with me over the past weeks to create an updated, modern business website for me. They have been knowledgeable, timely, and communicative throughout the entire process, and I could not ask for better service. I gave them vague instructions for what I wanted to complete, and they came up with multiple amazing designs, knocked it out of the park, and kept in touch through the entire process until it was implemented. I highly recommend their skillsets to anyone looking for website design and business consulting.

These guys are brilliant and make getting the job done easy! I’ve been so impressed with their professionalism and skills on multiple projects that we will use them again and again to help our creative agency build dynamic apps and websites. We put our trust in the right team!

It's nice to have a partner in lieu of just another vendor, generally, but when it comes to augmenting expertise that is lacking in one's own department, it becomes even more important. Alligatortek is the standard be which I judge all professional relationships. Over the last decade, nobody has added more value to our organization than them. Alligatortek has the people, the process, and the leadership to handle any development need we have.
