AppMakers USA Reviews & Testimonials
Yaakov Babani Manager at Growth Co.
5.0★
Small Business Review from Yaakov Babani
I work in client partnerships and one of the hardest things is remembering the context behind every relationship when you have a lot of them going at once. AppMakers NY created a better way to do that. At one point there was a client that had mentioned the same frustration three times and because the notes were scattered around, that pattern was completely missed. That alone made the project worth it. The team helped develop something that would actually be useful during a busy week, not another system people forget to update. I liked working with them and would absolutely use them for future projects.
Eliana Lubofsky Teacher at SAM School
5.0★
Mobile App Development Review from Eliana Lubofsky
AppMakers USA was a great experience! The team was professional, responsive, and easy to work with. They understood my ideas and helped turn them into a quality app. I'd definitely recommend AppMakers USA to anyone looking for reliable app development services.
Alexa Ginsberg Social Media Manager at Nanobébé
5.0★
Startup Review from Alexa Ginsberg
What stood out most about working with AppMakers USA was how attentive and helpful the team was throughout the project. They listened to our feedback, kept us updated and were always available when we had questions. Everything was handled professionally and we felt confident that our project was in good hands. Were very pleased with the final outcome!

Web Development Review from Mathias Willburger
The final product optimized the company's process as expected and has been well received by users. The company appreciated how well the Geeky Ants communicated, always punctual for meetings, and responsive to inquiries despite being in different timezones.
Deekshu Gunaga Review from Google

Deekshu Gunaga's Review Sourced from Google
Very poor hiring management experience at GeekyAnts. After scheduling the interview and making candidates wait for one week, the hiring team only said the application was “on hold” and mentioned there may be an update next month. After that, there was no response or communication at all. Candidates deserve proper updates and professional handling instead of being ignored. It was worst experience
Sankalp Deshpande Review from Google

Sankalp Deshpande's Review Sourced from Google
Don’t waste your time going for the interview. They’ll make you wait and then just tell you your application has been rejected without giving proper feedback Even though I have healthcare experience and cleared the relevant rounds, they still said I don’t have experience in BA. Feels like a total waste of time — waiting, interviewing, and then being rejected without proper feedbac

Murali Krishna Review from Google
5.0★
Murali Krishna's Review Sourced from Google
I worked with Sunvera Software on the development of a fitness app for a business. Sunvera delivered the app on IOS and Android platforms. Their development teams were easy to deal with. The app had some complex workflows and Sunvera handled it easily. Weekly reviews kept the development pace on track and kept us informed on the progress.My 5-star review reflects my recommendation of Sunvera for anyone else seeking to develop a solution. However, a well thought-out review must also have identified room for improvement. My suggestion for improvement is their software-bug tracking and closure process to keep the customer better informed. There were times where this was lacking during our project. Team members compensated by stepping up and doing the needful.
David Garrett Review from Google

David Garrett's Review Sourced from Google
Sunvera helped us develop an app for our product, HEYKUBE. They did an outstanding job, managing simultaneous iOS and Android versions, provisioning a backend server, and implementing core development for the app. The app incorporates graphics as well as a custom BTLE stack to communicate with our device. The team is great, and Ram provides steady leadership to make sure projects get done on time. I would highly recommend Sunvera to just get the job done for you.
chris georgieff Review from Google

chris georgieff's Review Sourced from Google
The team at Sunvera has been an invaluable partner for our company. Their approach to problem solving, their attention to detail, and ability to meet tight timelines have helped a young company like ours accomplish a great deal in a short amount of time. I highly recommend Sunvera for your next project. - Chris Georgieff, COO TollSense LLC
