Challenge

Signhost needed to support growing international demand with mobile apps that matched the security, reliability, and ease of use of its desktop digital signing platform. As a solution used across legal, finance, real estate, and healthcare, the app had to handle sensitive document workflows, verified identities, secure signing, and document management on the go. The client also needed ongoing modernization and maintenance for both iOS and Android.

Solution

Mood Up helped modernize and maintain the Signhost mobile applications for iOS and Android, focusing on stability, user experience, and secure performance. The team worked with Kotlin and Swift, including Jetpack Compose and Core Data for responsive mobile experiences and secure offline support. We also implemented CI/CD automation, integrated Firebase, Intercom, and Room, and continuously optimized real-time performance and data security.

Results

The mobile app enables users to send, sign, and manage documents securely from anywhere, whether they are closing deals, onboarding clients, or signing legal agreements. With support for verified identities from over 249 countries and more than 5 million digital transactions per year, Signhost’s mobile platform plays a critical role in keeping document workflows secure, paperless, and globally accessible.
