CHARGE SMARTER. NOT LONGER.

Pro turns your phone into a full solar advisor — here's everything you get:

— KNOW WHAT'S ACTUALLY HAPPENING —
• Battery Bluetooth (BETA) reads your battery's built-in monitor directly over Bluetooth. See what's pushing in (solar, your DC-DC, or both) and what your fridge or other gear is pulling out — without conflating them. Works with JBD and JK-family battery management systems (BMSs).
• Daily Battery Tracker projects your sundown % and runs a sunrise safety check from your current charge and system draw.
• Estimated Output runs your real panel + battery specs against live conditions and shows hourly wattage, recharge rate, and projected daily harvest. Updates every 15 minutes.

— CHARGE IN THE RIGHT HOURS —
• Best Charging Window (BCW) rolls through the day on live weather. Set a duration, pick a custom window, or let the app find the optimal one.
• 3-day solar outlook — see what the next few days charging looks like at your spot.
• Hyperlocal 15-minute weather — YOUR exact spot, not a regional average.

— SET UP TO THE DEGREE —
• AR Panel Alignment shows the exact direction and tilt with audio + haptic feedback to help lock it in. A real game changer for portable blanket users — about 25% more charge than guessing the angle by eye. Reposition with confidence each time, or set once and forget for the day knowing you’ve optimised your charging for today’s conditions.

— PLAN THE WHOLE TRIP AROUND SOLAR —
• Trip Planner: multi-stop solar forecasts so you can see what charging conditions are like where you’re headed to, not just where you are now.
• Your own trip archives and campsite notes. Record the great (and the not so great) parts of the trip - future you will thank you
• Use different equipment for different trips? Save multiple panel + battery profiles — switch between rigs in a tap.

Designed for the real world. Works in the outback, at the beach, in the mountains —anywhere you setup camp. Every calculation runs on-device. No reliance on cloud services or mobile coverage.

Our Honesty — live-weather, physics-based, real-conditions-aware outputs for your exact spot, right now. Plain talk on what we can and can't tell you.

Your Privacy — no ads, no tracking, no analytics, no accounts. Your spot stays yours.
