This was done for Hike Messenger about 10 months ago, took about 6 months from the start to get live. This was a huge update as compared to the previous ones as we were making a complete design revamp as well as a code rewrite. This project was slightly challenging and took a lot of effort from the whole team, it was an amazing project for me as it was my first big windows app project and with new platforms come new challenges. Definitely happy for those really positive reviews which have flowed in after the launch, do let me know what you guys think! You can download the app here.
Also Hike recently crossed 100m users!
