Get more from SoundCloud
Apps are what really make SoundCloud. There are more than 100 to choose from. Some cost a fair bit, but others such as SunVox cost only a couple of pounds and let record and directly upload to SoundCloud. If you're not comfortable creating original mixes, you can mix cherry-picked items from SoundCloud's extensive Creative Commons Licence menu and remix those.
You may not immediately want to share details of everything you've been working on, but there's the ability to share up to 100 tracks with trusted people via the free version of the software.
Once you're happy with your tracks, use the BandPage app to showcase everything on Facebook. If you're using one of the paid-for versions of SoundCloud, you can specify your best tracks as spotlight ones that are offered by default whenever someone visits your page.
You aren't limited to recording music. You could create a narrative of your favourite photos using the Instagram-based Story Wheel and select the best photos from your phone's camera roll.
If you install the free SoundCloud software on your iPad or Android tablet you gain an instant music player filled with all the tracks you've earmarked on the SoundCloud website. Commenting is less fiddly as you get a larger pop-up commenting box.
