How many BPH is the 32 Day Clock Easy Build? I'm struggling to find an Android app that will work, but maybe it'll be easier if I enter this number rather than have the app trying to figure it out.

It is in the manual on the page with the gear train diagram. Every clock is slightly different and you may not find an app with the exact ratio built in. This clock uses a 4.5:1 ratio, two 5:1 ratios, and a 26 tooth escapement to end up with a 14.84" pendulum at 5850 bph.
I use semi-random gear ratios and a variable number of escapement teeth to make the pendulum length be proportional to the size of the clock. Other clock designers often use 39" pendulums with a one second beat. This allows them to have a second hand, but they often end up with overly long pendulums.
