BigArrowHome
The only paramotor flight system with real-time fuel monitoring, VASI approach guidance, group flying, and a dedicated Wear OS watch app — all in one.
The Problem Paramotor Pilots Face
Today's pilots are forced to juggle multiple apps, devices, and workarounds just to stay safe in the air.
App Overload
One app for navigation, another for engine monitoring, a third for group tracking, and a timer to guess your fuel — nothing talks to anything else.
Fuel Guesswork
Most apps estimate fuel with a countdown timer. That is not real data. If conditions change, your "estimate" is dangerously wrong.
Subscription Fatigue
Many competitors lock essential features behind monthly or annual subscriptions. Basic safety features should not cost extra every month.
No Approach Guidance
General aviation has had VASI approach lights for decades. No paramotor app offers this — until now.
Two Apps, One Seamless System
A full-featured navigation app on your phone or tablet and a dedicated fuel monitoring app on your wrist — connected automatically.

Features No Other App Has
Everything You Need, Nothing You Don't
Every feature is built for real-world flying. No bloat, no paywalls for safety features.
Real-Time Fuel Monitoring
Direct BLE connection to the Tiggy Fuel flow sensor. See tank %, litres remaining, flow rate, pressure, battery voltage, and estimated runtime. Low-fuel alert with vibration and audio. Draggable fuel panel.
VASI Approach Guidance
Visual approach slope indicator within 5 km of your destination. Uses your altitude, distance, destination elevation, and glide ratio (3:1–30:1) to show On Glide, Too High, or Too Low.
Glide Range Ring
A live circle on the map showing maximum glide distance from your current altitude. Updates in real time. Know at a glance whether you can reach a safe landing zone.
Full Navigation Suite
Three map types (Standard, Satellite, Terrain). North Up or Track Up. Home, waypoints, and destinations with ground elevation. Direction circle, laser line, and track history.
Group Flying
See every group member's live position, speed, and fuel level on the map. Secure groups with name + code. No account or login required. Members auto-hide after 2 minutes.
SOS Emergency System
One-tap SOS sends your GPS coordinates and altitude to all emergency contacts via SMS and/or phone call. Google Maps link included. Set up before you fly.
Circle Wind Measurement
Fly a 360° turn and the app calculates wind speed and direction from your ground speed in each sector. Auto-completes when a full circle is detected. Validity colour-coded.
Traffic Light Indicator
Green, orange, or red at a glance tells you whether you are on course (±15°), slightly off (15–45°), or way off (>45°). No mental maths required.
Wear OS Watch App
Standalone fuel monitoring on your wrist. Circular gauge, runtime, flow, pressure, battery. Full calibration controls. Auto-connects to the sensor. Syncs data to your phone automatically.
Altitude Tracking
GPS (MSL) and AGL modes. Tap to toggle. Metres or feet. AGL uses your Home point elevation as ground reference.
Postcode Search
Search by UK postcode, address, or place name. Pan the map to any location and optionally save it as a destination.
Power Save Mode
Reduce GPS frequency, dim the screen, and extend battery life on long flights. Configurable update intervals from 10 seconds to 2 minutes.

Before vs. After
What changes when you switch to BigArrowHome + Tiggy Fuel.
Before
- One app for navigation, another for fuel, another for group tracking
- Fuel level based on a timer countdown — inaccurate and dangerous
- No approach guidance — guess your glide slope by eye
- No glide range awareness — can I make that field?
- Separate subscription for each app, adding up every month
- No fuel data on your watch — have to look at your phone in flight
- SOS means fumbling with your phone to text someone
After
- One integrated system for navigation, fuel, group flying, and safety
- Real fuel sensor data — actual flow rate, litres, and pressure in real time
- VASI tells you On Glide, Too High, or Too Low before you commit
- Glide range ring on the map — instantly see what you can reach
- No subscription. All features included.
- Full fuel gauge on your wrist — glance and fly
- One-tap SOS sends GPS + altitude to every emergency contact
