What's New in Solar Spotter

Plan your power before you leave, know it'll last while you're out, and take what you learned on the next trip. CALCULATOR (Free + Pro) — Work out what you need before you spend money or pack the car. Free: pick a place and a time of year, tick what you'll run, and see about what size solar and battery you'd want. Pro: test up to three panel and battery setups against a trip you've planned, using your own recorded draw once Energy History has enough days. Go bigger for a winter trip, or see what you can leave at home in summer. It also shows how it went last time you camped at or near there. Find it in the menu, just under Trip Planner. YOUR FRIDGE SETTING COUNTS (Pro) — Your fridge is usually the biggest draw at camp, and a colder setting in hot weather costs more. Each fridge now has its own setting, and the app learns what it really costs in the heat. Once it has enough days of your own readings, the Calculator plans each day's draw from it and shows which day will use the most power, and why. YOUR TRIP RECORDS WHAT HAPPENED (Pro) — Plans change. Stopped somewhere you didn't plan? A quiet question asks "Camping here tonight? Add it to the trip?", then fades. Say no and it asks if it was a rest stop on the way. Camp further along your route and it asks if you skipped the stops in between. Dates follow when you really arrived. Rename a camp, or edit the nights the app didn't see. Then plan the trip again off how it actually happened last time. YOUR NOTES COME BACK WITH YOU (Pro) — Write notes on a finished trip and they're saved to that place. Add it to a trip again and the app reminds you you've been here before. ONE APP, THE WHOLE POWER PICTURE — Weather, sun, panels and battery together, including Battery Bluetooth (Pro, BETA) reading seven battery types, and Energy History showing what your setup really did, day by day. Less time checking your gear, more time enjoying the trip. As always — no accounts, no tracking, no analytics. Nothing is ever linked to you.
