Velocity
Maintenance developmentopaqueShow more...
Development momentum is currently in a maintenance state, characterized by a long gap between the initial iOS release and the most recent Android update. With only two distinct versions identified in the history and a 697-day gap for the iOS platform, the release cadence is infrequent. The latest release provides no descriptive notes, leaving the specific focus of the update opaque. The current cadence of approximately 0.07 releases per week confirms a low-velocity maintenance profile.

Key takeaways for CoCoRaHS
Where is it heading?
The outlook for CoCoRaHS is declining as the latest version has introduced technical barriers that impede the core volunteer reporting mission. Without a shift toward stabilizing the data-entry workflow, the network risks losing its most dedicated contributors to simpler, more reliable alternatives.
- Technical instability and navigation friction in the latest release drive user frustration, which threatens the long-term viability of the volunteer data-collection network.
- The maintenance-mode release cadence suggests limited engineering capacity to address the reported bugs and UX regressions in the near term.
The SWOT
- Volunteer network effects create a defensible data-collection barrier
- Streamlining the reporting workflow to restore the legacy ease-of-use
