Major Source OÜ Delivered a Quality Mobile App Development Solution on Time

Siddharth Joshi / CEO | Oct 09, 2026

We were very happy with how this project went. Even with the time zone difference, responses usually came the same day and we never felt left in the dark. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

Since launch, everything has been stable and our team has adapted to it quickly. We would definitely work with them again.

Project summary

Our company worked with Major Source OÜ to build iOS and Android apps for our customers, including booking, payments and push notifications. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The project took roughly 5 months from kickoff to launch.

Easy to work with and very transparent on timelines and cost

Hannah Turner / Managing Director | Sep 28, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. The team asked a lot of questions early on, which felt slow at first but meant there were very few surprises later. Their project manager kept things organised and was quick to flag anything that might affect the timeline. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

We are already seeing better numbers than before the project. We are already discussing the next phase with them.

Project summary

We partnered with Major Source OÜ to automate document data extraction that our team was doing by hand. The work covered requirements, design, development, testing and launch support. Overall it was a 4-month engagement.
