2025 was great year fo us with the launch of new AvNav — with a complete remake of AvNav as a Progressive Web App. This gives us the foundation to build many new features using mature web technologies. AvNav started its life as the most innovative and the highest performance App for Android in 2014 and this remake helps maintain our lead. We will be introducing many new innovative features in 2025-26, such as Artificial Intelligence (AI) based flight planning, navigation and weather alerts, vertical profiles and 3D Terrain and Synthetic Vision PFD - please stay tuned.
