The annual discount is a bet that you'll still be using the app in a year. Put a number on that bet.

How to use the result
The expected monthly cost assumes that if you stop using the app, you stop paying after the number of months you entered. If that expected cost is higher than the annual price, annual is the better bet. If it is lower, start monthly. You can almost always switch to annual later once the app has earned its place.
Be honest with the slider. New fitness, language and productivity apps are often abandoned within a few months, while tools you use for work every day are much safer bets. Read the full guide: annual vs monthly billing.
