The opportunity
Apps should work in the conditions users face. Test older Android devices, different screen sizes and slow connections. Startup time, download size and battery use affect whether people keep an app installed.
How to approach it
Decide which tasks should work offline, such as viewing saved records or drafting a field report. Queue changes, show sync status and resolve conflicts deliberately. Compress images and warn before large downloads.
What to measure next
Research users across intended regions and roles. Observe how they recover from errors and seek help. Track task completion, crashes and support requests after launch rather than download counts alone.
