The mobile versions of many finance apps are cluttered at best and watered-down at worse. We knew we had to nail the right level of focus on mobile if the entire platform would succeed.

"The mobile versions of many financial apps" - could be more concise. How about: "Most mobile finance apps..."
"if the" --> "for the"
-"would" --> "to"
