We follow mobile-first approach, from websites and webapps we create to the apps that serve as endpoint of our webservices.
The apps we create follow standards and well-known conventions and they are all cross-device minded:
Apple
For Apple OSes: iOS, iPadOS, MacOS and VisionOS. Although iOS apps can be easily ported to iPad and Mac, Vision goes on a different track with spatial design, and a more immersive interaction with users.
Android
Up to version 36 and backwards compatible to those version 19. Framework based, hybrid at most, native where petinent without hassle.
Hybrid and KaiOS
Everybody is invited into mobile applications, so KaiOS based devices stays on the line with a low resource consumption version, so data is available to all members of the product.
Server Side
A Web Service is the layer where data is stored and processed in a syste completely apart from users devices. Development is available in the following languages: NodeJS, PHP, Java or even Python. These solutions are also modular and documented, based on LTS versions, so they can be easily extended at some point.
