About this app

Benefits you don't want to miss out on—now manage them all in one place.

Coupons, gift certificates, points, free trials, usage vouchers…

While the number of benefits in our daily lives is increasing, they are scattered across different apps and services, making them difficult to manage.

"Oh My! You Have to Use This" is a benefit management app that helps you record and manage scattered benefits in one place, ensuring you don't miss their expiration dates.

No more regretting, "I'm sure I had a coupon..."

Have you ever had this experience?

✔ You failed to use a gift certificate, and it expired.

✔ You forgot you had a discount coupon.

✔ You realized your points had expired after they had already been forfeited.

✔ A free trial led to an automatic payment.

✔ It is difficult to remember where and what benefits are available.

If even one of these applies to you, "Oh My! You Have to Use This" can be of help.

Key Features
Coupon Management

You can register shopping coupons, discount coupons, and more, and easily check their expiration dates.

** Gifticon Management

Register gifticons received via KakaoTalk, text messages, email, etc., to manage them and ensure they can be used before they expire.

Point Management

Record the expiration dates of various points and manage them so you don't forget.

Free Trial Management

Record the end dates of free trials for OTT, AI services, memberships, etc., to prevent unwanted automatic payments.

Subscription Management

You can manage subscriptions with expiration dates along with various other benefits.

Check by Expiration Date

You can check the benefits you need to use first in chronological order.

Used Benefit Management

You can neatly manage benefits by distinguishing between used and remaining benefits.

Recommended for:

Those who frequently miss out on coupons

Those who often receive gifticons

Those who felt it was a waste to let points expire

Those who want to prevent automatic payments for free trials

Those who want to manage benefits scattered across multiple apps in one place

Those who want to smartly take advantage of even small benefits in their daily lives

Why was this created?

I, too, often forgot about coupons and gift certificates.

Coupons were in shopping apps,

Gifticons were in messenger apps,

Points were in payment apps,

and I had to check my email for free trials.

Ultimately, the problem wasn't that there were no benefits, but that they were scattered.

So, I thought it would be great to have an app that could manage benefits from various services in one place, and I decided to develop it myself.

"Oh My! You Have to Use This" is this kind of app.

✔ It is not an app that finds new coupons.

✔ It is not an app that displays advertisements.

✔ It is an app that helps you make the most of the benefits you already have.

Recording is easier than remembering.

Starting today, don't miss out on even small benefits.

Oh My! You Have to Use This will be with you.
