About
START is an intermittent fasting app using cellular science to promote weight loss without diet or exercise changes. UppLabs delivered the full mobile MVP in 2 months, 30% ahead of schedule, using React Native and a serverless Firebase architecture. The app reached 1.5M+ downloads and 500K daily active users across 20+ countries, validating the concept for investor acquisition.
Challenge, approach, and impact
Single Developer, Multiple Roles
A modest budget prevented hiring separate Backend Developer, PM, and QA Engineer. One senior UppLabs developer assumed full responsibility across architecture, development, design coordination, and quality assurance.
No In-House Technical Foundation
The client had a strong product vision but lacked technical expertise for choosing the right technology stack, defining app architecture, and overseeing implementation decisions.
Aggressive MVP Timeline for Investor Readiness
The MVP had to be delivered within 2 months to meet the client's objective of acquiring investment. Any delay would directly impact fundraising opportunities.
Mid-Development Design Pivot
The client decided to revise the product design midway through development, requiring rapid agile adaptation without compromising delivery timeline.

“I came to UppLabs with a vision but no technical foundation. They not only built the app but guided me through every architectural and product decision. Despite a major design pivot mid-development, they delivered 30% ahead of schedule. START reached 1.5M downloads and that would not have been possible without their work.“
