What it does
Pitch Square opens straight to the gauge. Lay your phone on the roof deck or a rafter and read the pitch as X/12, with degrees and percent grade.
Hold and set zero
Hold freezes the reading so you can pick the phone up. Set zero on a known level surface if your sensor reads a little off.
Feel whole pitches
A light tick at 4/12, 5/12, 6/12 and every other whole pitch, so you don't have to look.
Squares and bundles
Enter the footprint and the pitch. You get roof area, squares with waste, shingle bundles, underlayment rolls, drip edge and ridge cap.
Bubble and torpedo level
Flat on a surface you get a round bubble for both directions. On edge it works as a torpedo level.
Pitch table
1/12 through 24/12 with degrees, grade, rafter factor and hip/valley factor. The table highlights your last reading.

Common questions
The reading is off by a little. How do I fix it?
Lay the phone on a surface you know is level and tap Set zero. Thick or uneven phone cases can also tilt the reading, so measure with the case off if you can.
Should I measure flat or on edge?
Flat works on the roof deck. On edge works along a rafter, a board or a fascia. Both read the same pitch.
My shingles come three bundles to a square, but my brand is different.
Bundles per square, underlayment roll coverage and ridge cap per bundle are all editable in the Materials tab. The app keeps your numbers.
Does it need the camera or my location?
No. Pitch Square asks for no permissions. It reads the motion sensors, which Android doesn't put behind a permission, and it never connects to the internet.
Is it safe to use on a steep roof?
Stay off wet, icy or steep roofs and tie off when you go up. Check the reading with a square before you cut.
How do I get a refund?
Refunds go through the app store you bought it from. The developer can't issue them directly.
