■ The tools you reach for first. Level is a dedicated, oversized, accessible level — a big bubble and a huge degree number you can read at arm's length. iPhone has a level, but it's buried inside the Measure app; Level launches straight to the tool. No internet, no account, no ads, no tracking. Turn on airplane mode and it still works. That's the whole point. Open it and you're leveling — instantly, no menus. No subscription. ------------------------------- ● Two tools in one ------------------------------- • Lay the phone flat for a true bubble level — a single glow tells you when it's dead level. • Stand it on an edge for an angle finder / inclinometer — pitch and roll, 0 to 90°. • A huge degree readout you can read across the room. • Tap "Set zero" to calibrate against any surface — countertops are rarely perfect. ------------------------------- ● Private and offline by design ------------------------------- • Reads only the accelerometer. No microphone, no camera, no network, nothing to upload.
