I want to build a mobile application for project management like Trello , with the following conditions:
1. runs on Android and IOS
2. Built with Xamarin and visual studio 2019
3. Has a local database so that it can work while offline. if it is connected to an online server, synchronization will be performed.
I mentioned Trello just as an example. definitely not as complex and good as that. I just need an initial platform to start, maybe it consists of a login form, project input, task update, image load.
