Key takeaways for Onyx: Martial Arts
Where is it heading?
The sports management market is consolidating around platforms that offer both administrative reliability and frequent feature updates. Onyx: Martial Arts remains exposed due to its current maintenance-only posture, which fails to address critical hardware-specific bugs that prevent club owners from accessing their data.
- Launch failures on Samsung devices prevent access to core services, which directly erodes the trust required for a £50/month B2B subscription.
- The maintenance-only release cadence suggests a lack of active feature investment, leaving the platform exposed to more agile competitors in the sports management space.
The SWOT
- Granular student progress tracking enables long-term retention
- Technique video uploads drive coaching engagement
- Discipline-specific feature sets could capture specialized academies

Read the full takeSince the last report: Onyx: Martial Arts has undergone no functional or pricing changes, remaining in a maintenance-only state for over six months. The analysis now explicitly links the lack of feature velocity to the risk of losing market share to more active competitors.
Bottom line
Technical stability on Android must be the priority, as the current launch failures directly undermine the value of the club management dashboard. Addressing this baseline reliability is the only way to defend the current subscription base against more stable, active alternatives.
