starbucksiphoneYou’ll soon be able to tip a Starbucks barista straight from your smartphone.

The Seattle-based coffee giant’s iPhone app, which accounts for more than 10 percent of its total transactions, will be getting an update on March 19 offering coffee lovers the ability to add a 50 cent, $1 or $2 tip to their order.

The tipping feature is part of a revamped Starbucks app which includes a new dashboard and a UI that takes a few design cues from Starbucks partner Square, CNET notes. The new app also includes something called “Shake to Pay,” which allows customers to shake their phones while inside the app to immediately bring up their Starbucks Card barcode.

The update, available in the US, Canada and UK, will arrive for Android users later in 2014.

Starbucks, which signed a deal with Google this past summer to improve in-store Wi-Fi, recently made security improvements to its mobile product after a researcher raised concerns about the way the app stores user names and passwords.
