Bolt Sports

Bolt Sports brings real-time feedback and measurable performance data into hockey training. GBot partnered with the product team over several years to build the mobile app that powers Bolt's hardware ecosystem.

Overview

Modern sports training increasingly runs on data, but the gym floor is unpredictable and time-sensitive. The Bolt app is the central hub connecting multiple BLE-enabled training devices during a session, turning live sensor data into drills, scores, and feedback — without making athletes or coaches think about the technology.

The Challenge

Training feedback only helps if it's instant. The app had to talk to several devices at once, deliver low-latency feedback while a drill is in progress, and stay rock-solid in noisy, non-laboratory environments — all behind an interface simple enough to use mid-practice.

What We Built

• A cross-platform Flutter app for iOS and Android.
• Low-latency BLE communication with multiple training devices simultaneously.
• Real-time drills, scoring, and performance feedback.
• Athlete profiles and session-history tracking.

Technical Highlights

• Reliable, low-latency BLE handling for several devices at once under high-frequency sensor data.
• A Riverpod-based architecture keeping live session state responsive and consistent.
• A training-first UX that hides the connectivity complexity from athletes and coaches.

Outcome & Impact

• A production-ready platform used by athletes globally.
• Stable performance under high-frequency sensor data.
• A foundation later carried forward under the HockeyShot brand.
