Case Study: a US-based digital health company achieves nearly 90% faster loading times with Toptal

A US-based digital health company cuts app loading times by nearly 90% with Toptal

A US-based digital health company offering a mobile app for back pain and posture exercises was facing challenges with its application. The app suffered from slow video loading times that disrupted user workouts and lacked essential features like account authentication and user feedback. Furthermore, it was only available on iOS, limiting its potential audience. The company partnered with Toptal for custom software and mobile app development services to address these issues.

Toptal optimized the video preloading process and implemented new features using Expo, TypeScript, and Firebase. Their solution included adding account authentication, database functionality, and user feedback capabilities. Toptal also developed and launched a full Android version of the app. As a result, average loading times for exercise routines were cut by nearly 90%, dropping from 3.8 seconds to just 0.4 seconds. The Android launch significantly expanded the app's potential audience and the new features enabled better subscription management and user communication.
