Agro Navigation

Works completely offline! No internet needed in the field. Save & export your tracks. One-time payment, no subscription required.

Save chemicals. Save money. Drive straight.

Agro Navigation is a GPS guidance app that helps you drive straight lines across your field — so you never overlap or miss a strip when spraying, fertilizing, or spreading.

No expensive equipment. No subscription. No internet required. Just your phone and GPS.

WHY FARMERS USE IT

Every pass with a sprayer or spreader costs money. Without guidance, you overlap 5–10% of your field — wasting chemicals and fuel. Agro Navigation shows you exactly where you've been and where to go next.

On a 100-hectare field, that's up to $500 saved per season. The app pays for itself on day one.

HOW IT WORKS — 3 SIMPLE STEPS

1. SET DIRECTION — Drive to your starting point and tap "Set." Green guide lines appear.
2. START WORKING — Tap "Start" and a trail appears behind your tractor showing covered area.
3. ADJUST WIDTH — Make your first turn, set the width with the slider. Follow the green lines.

No complicated setup. Three taps and you're working.

KEY FEATURES

• Works 100% offline — no cellular signal, no Wi-Fi, no problem • Built-in compass for accurate heading • Visual trail shows exactly where you've worked • Adjustable working width with a slider • Save, review and export your tracks as KML • Pan and zoom to see the full picture • Manual compass correction for tricky devices • GPS heading fallback when no compass available • External GPS/GLONASS receiver support via Bluetooth

ACCURACY — 3 OPTIONS FOR EVERY BUDGET

Uses your iPhone's GPS/GNSS. Accuracy depends on your model:

1. iPhone GPS — works out of the box: iPhone 14 Pro and later: 10–30 cm (L5 dual-frequency GPS) Other iPhones: 1–3 m under open sky

2. Commercial Bluetooth GPS receiver (~$150): Plug & play, no assembly required ~1 m accuracy

3. DIY GPS receiver (~$50): Build your own with our instructions 10–20 cm accuracy — same as $2,000 systems

WORKS WITHOUT INTERNET

You work in the field — where there's no signal. Agro Navigation runs entirely on your phone. No cloud. No login. No data uploads. GPS satellites are always available, even in the middle of nowhere.

PERFECT FOR

• Spraying herbicides and pesticides
• Spreading fertilizer
• Any operation where overlap matters
• Farmers who can't afford $2,000+ guidance systems

THE MOST AFFORDABLE WAY INTO PRECISION FARMING

Hardware systems cost $2,000–15,000. Subscription apps charge every year. Agro Navigation is a one-time purchase — no recurring fees.
