Recently, I started at a new school and needed a solution to manage all of my classes and homework tasks.
At my old school, this wasn't a problem as there was a system that all the teachers used to set homework and you could see what you had to do and by when.
This time was different. After trying about 5 of the top planner apps on the Google Play Store, I settled on School Planner. I used this for about 2 weeks, but there was one, major problem. There was no web interface. As I spend most of my time on my computer not my phone, this was a dealbreaker.
So, I decided to create my own planner app. I present to you: MrBBot Planner (name subject to change!):
You can access it here: https://planner.mrbbot.co.uk/
The source code can be found here: https://github.com/mrbbot/planner
There isn't any mobile app at the moment, but by adding the page to your home screen, you can make it act as if it is one (splash screen and all).
