Slope Level
A level that answers in the unit your trade actually uses.
Every level app on your phone says 12 degrees. Nobody pours a
slab in degrees. Slope Level reads the same tilt as
¼ in/ft, 2 %, 4/12,
21 mm/m or 1:48 — and tells you how much the
far end drops over the run you are working on.
Free forever
The level itself, flat and on edge, with a big readout, degrees, the zero, an
alert when it hits level and holding a reading. No ads, no subscription, no
account.
The one-time unlock
Trade units · the drop over a distance · measuring an angle in a photo · exporting
that photo with the reading written on it · saved measurements with a name, a note
and a photo · and a converter for when the plan says 2 % and you need it per foot.
Honest about what it is
After zeroing, around ±0.2°. That is what a phone sensor gives — this app and
every other one.
