Still worth keeping this month?
SUBWORTH helps you decide, on a regular basis, whether each
subscription is worth keeping, worth a second look, or worth cutting.
■ Not per month. Per year.
¥980 a month feels small. It's ¥11,760 a year.
You see the yearly cost the moment you add it.
■ One tap on the days you use it
It doesn't count launches. Just whether you used it that day.
Once a day, and it never double-counts.
■ See what one use day costs
¥1,590 used on two days a month is ¥795 per use day.
Being expensive isn't the problem. Not using it is.
■ VALUE shows its reasoning
It won't just hand you an A to E and stop there.
The usage rate, the cost per use day, and why it landed there are all on screen.
■ Review them one at a time
Go through each subscription and choose keep, review or cut.
Swipe left or right if you prefer.
■ "Cut" and "cancelled" are different
Deciding to cut doesn't count as savings.
Only once you've actually cancelled does the yearly figure add up.
■ Everything stays on your device
No account. No connection to your bank or credit card.
It never reads what you do in other apps. No ads.
