I bought this app trying to get my old padlock unlocked. It took about 30 minutes to figure out the instructions (They aren't all that descriptive.) and another 30 to work through the possibilities, but it worked! Best $1 I've ever spent!
Right when I downloaded the app I knew what to do(no instructions!) because I saw a little plus sighn at the top and I just tapped on it then you name it and scroll to put in the code! And on the main page you just have to hit the name of your combo and it pops up!
Lock Master keeps track of your lock combinations. Bicycle locks, gym locks, storage unit locks, all those combinations can get confusing. Store them all here.
