This document summarizes research comparing app usage habits of iPad and smartphone users. Some key findings include: - iPad users get content updates on their favorite topics over 10 times per day, engage with more apps, and have more paid apps than smartphone users. - iPad users are much more likely to pay for apps across categories and subscribe to paid subscription apps. However, they also expect value and will stop using paid apps quickly if not satisfied. - The research could not determine if the higher spending on apps by iPad users is driven by the early adopter audience or the larger screen form factor of the iPad.
