## What is TrailLevel?

TrailLevel helps camper, trailer, and RV owners level their rig without accounts, subscriptions, or internet access.

Place your iPhone on a stable surface, check side-to-side and front-to-back slope, then see an estimated lift amount based on your saved vehicle width, wheelbase, and leveling block height. TrailLevel also includes a simple local checklist for arrival and departure routines.

Features:

- Live side-to-side and front-to-back level readings
- Estimated lift amount for each direction
- Leveling block count estimate
- Saved vehicle profile
- Imperial and metric units
- Local arrival and departure checklist
- Works offline
- No account, ads, analytics, or tracking

TrailLevel is built for quick campsite setup. Your vehicle measurements and checklist progress stay on your iPhone.
