My friend launched a dry cleaning and laundry delivery service app called Clean Basket. If you are too busy to do your laundry or big bulk of laundry that needs to be done like your summer blankets or sneakers try "Clean Basket."
The best part of the app is they pick up and deliver at the time and place you want them to! So, if you are going on a business trip and need your suit to be delivered to your office they will do it! Some price are actually cheaper than dry cleaning nearby my house.
It's available on android and ios. The English version is available only on android. iPhone users - the app is really simple and no online payment is needed so you can ask your Korean friend to help you.
For first-time users they have 2,000won discount coupon and they have chooseok promotions going on right now on laundry services.
Hope this app makes your life a little bit simpler! :)
