Production-grade quality
Built to the same engineering bar as paid SaaS tools — accurate algorithms, audited logic, responsive design and accessibility-tested interactions.
Common use contexts
- Flight route planning
- Marine navigation
- Travel distance estimation
- Geo-fence / proximity calculations
