1. Developer savings calculator
The starting hours are illustrative. Replace every number with your own project estimate. Annual maintenance is multiplied by the selected number of years.
Monthly API usage
Free: 5,000 at $0 · Starter: 35,000 at $49 · Growth: 80,000 at $99 · Scale: 200,000 at $250 · Enterprise: custom quote. The calculator assumes these API call allowances reset monthly.

4. What's involved in building your own indoor navigation system?
The default 176-hour first-year estimate is a limited implementation using existing smartphone APIs and software libraries, not a full production-grade equivalent of IGC Fusion. Explore the individual tasks behind each estimate below.
Initial setup 8 hours
- Configure development environment and dependencies: 2 hours
- Enable required smartphone sensors and permissions: 2 hours
- Set up mapping, positioning and sensor libraries: 2 hours
- Establish initial navigation data structures: 2 hours
Positioning and navigation logic 80 hours
- Sensor processing, accelerometer, gyroscope and compass: 12 hours
- Step detection and pedestrian dead reckoning: 12 hours
- Combine GPS, motion and heading into a position estimate: 16 hours
- Basic drift correction and confidence handling: 12 hours
- Floor detection and vertical movement: 12 hours
- Navigation guidance, distance, bearing and direction: 12 hours
- Arrival detection and uncertainty handling: 4 hours
Application integration 24 hours
- Connect positioning outputs to the existing application: 6 hours
- Build navigation interface, arrows and distance display: 8 hours
- Connect destinations and route information: 6 hours
- Handle app state, permissions and lifecycle events: 4 hours
Testing and validation 32 hours
- Test positioning accuracy and walking drift: 8 hours
- Test across smartphone models and sensors: 8 hours
- Test floor changes, lifts, stairs and escalators: 8 hours
- Resolve integration issues and regression tests: 8 hours
Annual maintenance 32 hours per year
- Android and device compatibility updates: 8 hours
- Sensor and positioning improvements: 8 hours
- Bug fixes and performance monitoring: 8 hours
- Regression testing following updates: 8 hours
Why does IGC Fusion start at 26 hours?
Our illustrative IGC-side hours are 2 hours for setup, 0 hours building the underlying navigation algorithms, 8 hours connecting the app, 8 hours integration testing and 8 hours annual maintenance. Developers still build their own user experience and verify integration behaviour. They do not need to recreate IGC Fusion's positioning algorithms.
These figures are editable planning assumptions, not measured customer averages or guaranteed savings. A comprehensive production-grade indoor positioning solution can require substantially more engineering and real-world validation. API subscription costs use the selected plan; other deployment and infrastructure costs are not included.
