Cross-Platform
Software Engineering

At 69 Degrees, it is our firm belief that fantastic mobile apps for iOS and Android are best built using industry-leading technologies like Flutter, React Native, or Xamarin.

As product-minded engineers, we advise, design, and program in long-term and short-term app projects.

Why Cross-Platform?

Time to market

Depending on the chosen development approach, 50-95% of the codebase can be shared across target platforms (such as iOS and Android). This dramatically speeds up development.

Reduced cost

Imagine if you had to fund one team each for iOS, Android, and possibly desktop or web. With a cross-platform solution, a single team can handle all target platforms.

Reduced risk

Due to the higher speed of development, you can test new ideas faster on the market and thus considerably reduce the risk of making the wrong calls.

Better communication

Developing the same features multiple times increases the complexity of coordination. Rely on cross-functional teams who speak a common language.

Outstanding quality

Stability, performance, and sound design are essential quality criteria for our apps. A modern cross-platform framework provides ideal conditions for this.

Open-source

Flutter, React Native and Xamarin are open source solutions from industry leaders. They therefore offer long-term investment security for your project.

Insights

Model-View-Update (MVU): How Does It Work?

MVU (also known as The Elm Architecture) seems to be one of those things which are a mystery to most of us. Until all of a sudden, we understand it and never wanna miss it again. It's not all that complicated.

MVU For Native Xamarin Apps

While Fabulous provides a great way to build Xamarin.Forms apps with F# and The Elm Architecture, there has been no such opportunity for Xamarin.iOS and Xamarin.Android. Yet. Here it comes.

Certificate And Public Key Pinning With Xamarin

Are you securing the communication between your app and its backend with HTTPS (SSL/TLS)? Fantastic. But how do you make sure the other side is authentic? Read on on how to do this with Xamarin for iOS and Android.

Just drop me an email or give me a call. I look forward to hearing from you.
