The world is currently full of apps! Like every other resource in the internet, many of these apps are useful, but a good number of them are not depending on who you are, and what you are looking for. Many times, there are resources you don't even know exist; so you don't even know if you'd need them or not.
For creative people, Padlet is one of those apps/website that'll pull the plugs on your creativity. You will be grateful someone invented it!
I came across in one of the online courses I took at Futurelearn - my fellow students used it to present their assignments in such a beautiful way that I fell in love with it!
Go find love! Go find your muse!!
