Client voice

What our clients say.

In their own words, from the founders and leaders we build for. All reviews

  • The developers at Appsums did 8 apps for our company so far all published by GooglePlay and the App Store. They are committed, diligent, cost-effective and deliver results quickly. They fix bugs with relentless efficiency and I would highly recommend them if you need an app or website to be custom built.

    Dr Richard McMahon Dr Richard McMahonCEO / Founder, SwiftDoc Pty Ltd
  • Azad & his co-worker, I found them most technical and prompt in giving solutions to my requirements. They have all guts to go beyond what you think and bring to them. I would definitely recommend this team to go with it.

    Ryan Kuriakose Ryan KuriakoseCEO / Founder, Orphidia
  • The team delivered beyond my expectation as in the early stages I was little hesitant in choosing this small team for Video Streaming project, but team at appsums proved me wrong by all means. I would simply recommend Appsums to any.

    Zaid Sameer Zaid SameerCEO / Founder, Zee Media
  • We required a complex set of apps to be published in the App Store and Google PlayStore for clients to use worldwide. The apps must talk to a central database and rely on numerous APIs and custom coding which all works seamlessly. The team are very experienced with years of post Graduate experience in computer science and programming. The simple fact is that they deliver and we would not hesitate to use them again for any app coding, web design, SEO, API development, app publishing, debugging, website design and cloud computing, cloud servers, SSL functions, database management and on-going IT support. It is a rare thing indeed to find a company that is as dedicated to your success as the team at Appsums.

    Hannah Elman Hannah ElmanCFO, SwiftLaw Pty Ltd
  • My experience with AppSums has been from the beginning extremely trustful and transparent, which I think is the key factor when you are outsourcing the development of a product overseas.

    Alberto Martin Alberto MartinManaging Director, Quiero Inc
  • I contacted the Appsums team a couple of months ago through LinkedIn. I asked them to create and take care of my professional website in UAE. Mr. Azad immediately proved to be competent and available. I definitely recommend Appsums and Mr. Azad to my Colleagues and friends!

    Dr Sergio Velanti Dr Sergio VelantiMD | CEODubai, UAE
  • Working with Appsums technology has been a wonderful experience. They went above and beyond to transform a concept into a reality. We asked them for the world, and they gave us a whole universe.

    Sophie Solimini Sophie SoliminiCEO / FounderToronto, Canada
  • Working with Appsums has been one great experience. They are great in understanding the requirements but what is more important team is very flexible in implementing feedback and doing iteration loops.!

    Ivan Andabak Ivan AndabakCEO / Co-FounderZagreb, Croatia
  • We have provided Appsums a very tight timeline to build an App for our Company and their team exceeded our expectations. They completed my dream Project Couture Singapore in very less time.

    Kia Lim Kia LimCEO / Founder, Couture Singapore
  • We’ve been working with them for over 2 years now and we couldn’t be happier with the extreme value they’ve brought to us. Azad and Hashim were by our side throughout all the steps of our Patients Education Mobile App development from beginning discovery phase to screens designs to implementing processes and features, making sure everything was how we intended it every step of the way. They are true Business PARTNERS.

    Danish Khan Danish KhanZonal Account Manager, Novo Nordisk
  • I have been connected with the team for a few years and my experience has been really good. I have worked on several projects with the team and every time Azad and his team exceed my expectations. They work great because they share everything transparently and there are never any surprises for me. I continue to work with them on several other projects.

    Ankur Bhardwaj Ankur BhardwajCEO / Founder, Flexus Solutions, LLC
  • I had a product was developed in bad way and I almost lost it but then AppSums team took it over and fixed everything and we are almost finished, my product will see the lights soon inshallah because of them
