The scope included development using Flutter and Supabase.

• A fully functioning cross-platform app (iOS and Android)
• A custom admin dashboard to manage all app content
• Audio player functionality with sleep timer, loop settings, and offline downloads
• Bluetooth device detection and pairing features
• Integration with Supabase backend, including storage, database, and authentication
• Ongoing support during app submission and launch preparation

The project was a clear success, with the app now fully functional and live on both the Apple App Store and Google Play. 

Describe their project management. Did they deliver items on time? How did they respond to your needs?

Project management was smooth and professional throughout. Communication took place over Slack, and the team was highly responsive to questions, feedback, and change requests - often replying within minutes.

They delivered the core milestones on time and were flexible in adapting the timeline when we needed to reprioritise features or tweak the scope. We got weekly updates on tasks completed and had clear visibility into what was being worked on.

Even when unexpected issues came up (e.g. Bluetooth behaviour on Android or App Store submission requirements), the team handled them quickly and transparently. Overall, they showed a high level of ownership and a genuine desire to deliver a great product.

Are there any areas for improvement or something HotShots Labs could have done differently?

Nothing significant comes to mind. We were really happy with the overall experience.
