Read the full case study

“Rownd radically simplified our mobile app onboarding process to the point where we just need to get traffic to our website and the rest takes care of itself.”

- Simon Karmarkar, Founder , RefundWiz and MasRefund


MásRefund is a fintech app that helps underserved communities quickly file their federal and state taxes and get their refund as fast as possible.  They make "filing taxes as easy as 1, 2, 3". Their mobile apps are built in native iOS and Android and their website is on Wordpress.


Help get website visitors to find and download the app

There is a lot of competition in the app store for refund apps, so they needed a way to get traffic from the website to the correct app and then log them in ASAP.

Needed passwordless solutions

The previous solution required a password and they wanted to add Google and Apple sign-in options. Their developers told them that would take 4-6 weeks.


Rownd Authentication Engine

When it came time to implement a new authentication solution for MásRefund, Simon and his team turned to Rownd's Authentication Platform and professional services to help them onboard.

With Más Refund's apps built in native Android (Kotlin) and iOS (Swift), and their backend using Node, Rownd's SDKs made it easy to integrate the new system across all platforms.

"Rownd's mobile SDKs are a fantastic tool for any developer looking to integrate a seamless authentication experience," said Sam Cho, a technical advisor for MásRefund.

"Their visual elements, like modals and sheets, make the process easy and intuitive. Plus, the fact that their SDK was able to replace over 20 separate pages in the MásRefund app is a testament to its efficiency and power.  I wish we started with Rownd on day one."

Rownd also implemented Rownd's "deep sign-in links" to help MásRefund's website visitors to find the correct app and be automatically logged in, saving minutes in the process.
