What it is
A realistic dial lock on the screen with step-by-step teaching and timed practice. It is for new students, gym members and their families who worry about opening a lock for the first time.
Why it looks interesting
Two small apps have appeared for this oddly specific need, which shows that a tiny problem can still find paying users. The signal is small and seasonal, but it is an excellent first project to learn with.
How it makes money
A small one-time unlock with free basic practice.
Apps to study
Watch out
Demand peaks at the start of a school year in markets where lockers are common, so expect quiet months. Use a neutral lock design, and collect no personal data, since younger students may use it.
