If you use Starbucks' smartphone app on the daily get ready for an update on Wednesday, March 19.

The update will offer customers various new options such as the "Shake to Pay" that will bring up your payment barcode no matter what you're doing in the app as well as the ability to see all your account information from the home screen. Starbucks is boasting digital tipping as the most important feature in the update.

After using the app to pay customers will be given the option to tip their barista through the app up to two hours after their purchase. For now, customers can only tip .50, $1, or $2. The biggest complaint customers have about the update is the inability to write in their own tip amount.

Using a gift card to tip was an idea brought up by several Starbucks customers nearly six years ago. Until the release of the updated app the chain only accepted cash tips, which left credit and debit card users in an awkward situation when they were short on cash. Even with the new update customers still won't be able to use a physical gift card to tip, only app users will be able to pull from their Starbucks Card for gratuity.

For now the new update will only be available for iPhone users, Android users will receive the update later this year.
