Yes! Sling Money only works on smartphones. We do not have a browser version for the moment (we're exploring the idea at the moment, get in touch with us if this is something you're interested in). You need a recent smartphone running iOS or Android in order to:
Use the Sling Money app
Set up a Sling Wallet
Send Sling Links
You do not need a smartphone in order to redeem a Sling Link to your bank account, debit card, or mobile money wallet in our supported countries.
