Yes, there is an app for serious shavers. It is called Shaving Buddy, and it does the following:
– Record your shave in seconds and give it a rating or comment!
– Have an overview of all your shaving items in one place. Make notes (condition, cost, etc.) on every piece of equipment you have.
– See how your razors perform based on your rating.
– Coming soon: Shaving Buddy will always tell you how often you used that blade currently in your razor.
It also lets you make an inventory for all your:
– Soaps & Creams
– Additional care products
