OST released OST Wallet SDKs for Android and iPhone March 29, 2019. These Wallet SDKs enable any business to integrate Brand Tokens into their app seamlessly without requiring an additional app. This approach is based on a ton of customer research during which we discovered that what brands want most is seamless integration into their existing apps. 

OST may release a standalone wallet later this year, but it's not high on our clients' priority lists and our roadmap is prioritized by our clients' needs.
