TrailerTilt

Stop hanging out the window with your phone trying to read a $4 bubble level on the fender.

TrailerTilt turns your iPhone into a real leveling tool for your trailer. Park, glance at your watch, and know exactly which corner to lift and by how much. The bubble lives on your phone, your Apple Watch, your Lock Screen, and your watch face — so you can see it from the truck.

Works for travel trailers, fifth wheels, horse trailers, boat trailers, utility trailers, off-grid camp setups, and anything else you need to sit flat.

WHAT IT DOES

• Big, readable bubble level with a green zone you set yourself (1.0° default, 2.0° if you've got an absorption fridge, whatever you want per rig) • Apple Watch app and complication, so you can level from the driver's seat • Live Activity on the Lock Screen and Dynamic Island — leave the app, the readout follows you • Home Screen and Lock Screen widgets • Tells you which corner to lift and roughly how much, in inches, blocks, or jack turns • Catches when you've bumped the phone mid-level and offers to re-zero • Locks the reading the moment you hit level so the numbers stop dancing while you walk around to set chocks • Optional reminder a few minutes after you level — handy if you're on jacks or soft ground and want to re-check once it's settled

SAVED SITES

• Save the spots you camp at with a name, photo, coordinates, and notes • Sees when you're parked at one you've saved before • One tap opens directions in Apple Maps • Share a site as a Maps link in Messages, Mail, anywhere • Export the whole list as JSON whenever you want — they're your sites

MULTIPLE TRAILERS

• Make a profile for every rig you tow • Each one keeps its own calibration, capacity, fridge type, and jack height • Quick switcher up top on the main screen

APPLE WATCH

• Standalone watch app — reads tilt right on your wrist • Rust means adjust, sage means level. No squinting at numbers if you don't want to • Complication for any watch face • Haptic tap when you hit level so you don't even have to look

LIVE ACTIVITY + DYNAMIC ISLAND

• Compact and expanded layouts with pitch, roll, and what phase you're in • Stays on the Lock Screen so you can level with the screen off — easy on the battery • Stops on its own when you confirm level or close the app

PRIVACY

• No analytics. No advertising IDs. No tracking. Nothing phones home • No accounts, no logins, no servers I run • Your sites, rigs, and settings sync through your own private iCloud. I can't see any of it • Sign out of iCloud and it all stays on the device

The app only asks for what it actually needs: motion for tilt, location to tag sites, local network if you want to pair an iPad as a big-screen display, camera and photos if you want pictures on your saved sites.

BIG-SCREEN MODE

• Prop a nearby iPad or Mac on the dash and use it as a giant readout while you back in • Talks over local Wi-Fi only — no router, no internet, no cloud • You confirm the pairing on both ends every session
