  • Appstem did an exceptional job building Tesla’s Marketing iPad App. We are tough customers, expecting the same excellence in our app designs and interactions as our cars, and Appstem delivered a fantastic product. The team was also very responsive to our needs and tackled issues that arose in record time.

  • Appstem has been awesome to work with. They took over a project we had that another vendor had worked on, and turned it around and completed it quickly. Their team was responsive and offered suggestions and expertise when we asked for them. We are so happy with the results that we are using them for our next app.

  • At Lionsgate we worked with a number of solutions providers and mobile app developers, but Appstem really nailed it when coming up with creative ideas, involving a location-based social strategy, and brilliant execution for one of our major television shows.

    Alex B., Lionsgate

  • We had such a good experience working with Appstem that they took over the iOS development as well as Android. The Appstem team has been great to work with, they currently support all our development enhancements and new features for our iOS, Android, and web platforms. They’re a pleasure to work with and I would highly recommend them for your mobile development projects.
