Describe the scope of work in detail. Please include a summary of key deliverables.
In this project we rebuilt our original application from scratch for the latest version of Flutter to remove some dependencies. The team quickly grasped the application’s essence and figured out how to work with the existing survey format and databases. They worked with us step by step and clarified all the details until they were certain they understood all the requirements correctly.
After five months, the application was published on the Apple and Google stores with all the necessary features. Additionally, HotShots labs helped us refresh the look and feel. We got positive feedback of the new application.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
Most importantly, the app is finally available on both platforms, previously it was published only on Google Play, which means significant increase in access to our application. Also, the application’s responsiveness improved significantly. The user interface has also been improved significantly.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
HotShots Labs demonstrated a highly organized and transparent project management. For real-time communication, we primarily used Slack. When it came to task management, we were integrated into their ClickUp workspace that facilitated easy communication. Any issues were communicated proactively, allowing for adjustments to be made. Issues were openly discussed and responded to. We found the team to be very responsive and that they care about their work.

What was the size of HotShots Labs’s team?

Describe the scope of work in detail. Please include a summary of key deliverables.
The scope of work involved developing an app for both Android and IOS that required integrating an existing API. We had an old version built on native technologies and needed to completely redevelop it with a new design. The app also had a Firebase integration for user auth (login, signup, forgot password).
There are about 10 pages, which will primarily be tables with some filtering functionality. Additionally, the app has integrated graphs, which involve presenting data in a visual format to help users understand and analyse it more effectively. Also, the app was published to Apple and Google stores.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
Users are satisfied with the new version.
It’s fast and stable.
Users are now more engaged which means the revenue potentially can increase.

I can say that their project management was first-rate. The team was receptive to my requests throughout the project and was able to deliver all milestones within the deadline. Communication was also excellent throughout the project.
The team was always available to answer my questions and address any concerns I had. They made sure that the finished result exceeded all of our specifications and expectations by regularly updating us on the status of the project and responding to our feedback.
