This app is built to help you track your pedal builds and the inventory of parts. As you build pedals manually cross referencing your inventory is slow and tedious. With this app you can simply populate your inventory. Then add a pedal build and from the bill of materials add parts and you will be alerted if they are already in your inventory or not. Additionally, you can create a list of parts needed for that next order!
