There are no controls except a reset button. Maybe this is a data reaper app... ### 5/5 — The Best?!?! *2018-05-14, version 1.1.1* This app is the best, my cousin jumped off a building to measure the height of the building and it worked?! ### 1/5 — Pap *2015-06-21* No instructions does not work rubbish ### 5/5 — Good And Bad.... *2015-06-10, version 1.0* If you don't have a outerbox or pillows on the bottom where you dropped it at. I have the iPhone 5s and I dropped my phone at the top of my stairs with pillows on the bottom where I dropped it. So ye. It's 16.some other inches tall. So ye. I like it. ### 5/5 — Amazing!!! *2015-01-29, version 1.0* This app is by far the best app on the entire AppStore! It's so useful, except for the fact that I broke my iPad after trying to see how tall my house is. 😄 ### 5/5 — What a great tool. *2015-01-29, version 1.0* Now when you want to know how deep a hole is or how high the building was you just jumped off of you will have an exact measurement. ## Frequently asked questions about How Deep Is It? ### How does How Deep Is It? work?
