Steps: (Thanks to Slickdeals)
- Install the CapTune App (iOS or Android)
- Click on 'Select your music' or any other Audio Sources in App
- Select TIDAL from the Audio Sources list
- Click 'Sign Up to TIDAL' and input your information
- You will then be prompted to open or download the TIDAL App (Your 3-Month TIDAL HiFi subscription will now start)
Once in the TIDAL app, you can cancel the subscription straight away so you won't be charged, and have 3 months free :) (Go to My Collection -> Settings -> Manage Subscription -> Subscription -> Cancel Subscription)
Thanks Spackbace,
Wasn't able cancel my subscription through the iOs app but I logged in to their website and did it from there.
