I use this For me itss quite useful. You can write the tasks that you want to get done in the 'To-Do' list. There are 4 sections you can move your each 'To-do' . ('Do today', 'In progress' , 'done')
This helps me to keep myself organized with the workload. There's also a timer, which is very handyyou can set it to ring every 30 minutes for example and take a few minutes break.
Never heard of this one before, gonna give it a spin.
Cheers. Good post OP, some will find this useful.
