NMEA Talker is a navigation utility for iOS that streams RTK network corrections to external GNSS hardware for centimeter-level location accuracy.
The App DNA
What makes this app unique?
It removes the connectivity friction between professional-grade survey receivers and iOS devices, provided the user utilizes the developer's proprietary hardware accessories.
For Surveyors, GIS professionals, and field technicians requiring centimeter-level GPS accuracy on iOS devices.
What does it look like?
Key features
Processes RTK network data for centimeter-level location accuracy, acting as a B2B unlock for proprietary hardware.
Streams GPS corrections to external receivers, enabling professional-grade GNSS workflows.
Interfaces with proprietary cables and Bluetooth modules to bridge iOS with GPS receivers.
How much does it cost?
The app is free to download but functions as a utility gate for the developer's proprietary hardware accessories, which are required for operation.

Key takeaways for NMEA Talker
Where is it heading?
The professional GNSS utility market is shifting toward universal, software-defined connectivity that bypasses proprietary cables. NMEA Talker's reliance on legacy hardware-software lock-in leaves it exposed to churn as users migrate to more flexible, actively supported alternatives.
- The 1,742-day update gap indicates a maintenance-only posture, which increases the risk of sudden failure on newer iOS versions.
The SWOT
- Proprietary hardware-software lock-in creates high switching costs for existing field teams
- Native RTK client enables centimeter-level accuracy on iOS
- Expand NTRIP 2.0 caster support to capture modern GNSS workflow migrations
Next best moves
