Felicity

Felicity is the third and final app of the three project I planned for my own learning, the first two are Positional and Inure App Manager.

The development of the app has started and if you've used the first two apps you might wanna join the Telegram Channel and become the part of the whole initial development process.

I am taking my time developing it because I want it to exceed my own expectations and by that I mean the quality of the software. I hope you are patient enough until the first few results :)

The project will be developed under the codename Felicity, the final name maybe updated in the future.
