About this app

Tsuikey

Tsuikey gently delivers requests and reminders to you, your partner, or your family—right when they’re needed. Let the app handle the follow-ups, so you don’t have to keep asking.

Tsuikey is a reminder app designed to reduce the frustration of requests being forgotten—and the emotional burden of having to ask again.

Instead of leaving one person responsible for remembering and following up, hand that job over to the app. Tsuikey acts as a neutral go-between, delivering reminders to you, your partner, or your family at the right time.

■ Create personal reminders in seconds
Capture a reminder the moment it comes to mind using your voice or text. Review the details and time, then save it right away.

■ See today’s tasks at a glance
View all the reminders you need today in one clear list. Tsuikey keeps reminding you until each one is done. If now isn’t a good time, choose “Later.”

■ Let Tsuikey follow up with your family or partner
With the Family Plan, you can send requests to your partner or family members through the app. Tsuikey follows up at the right time, so the person who made the request doesn’t have to keep asking.

■ Get things done faster with widgets
Use Home Screen and Lock Screen widgets to check your next reminder, add one by voice, or complete an active reminder.

■ Set recurring reminders
Create reminders for daily, weekly, or monthly routines such as chores, medication, items to bring, and routine checks.

■ Family Plan
The Family Plan includes reminders for your partner and family, an ad-free experience, and family sharing for up to four people total, including the subscriber.

Monthly: ¥300
Annual: ¥2,200
2-month free trial

Your subscription renews automatically when the free trial ends. You can cancel anytime in Google Play’s Subscriptions settings. After cancellation, you’ll retain access through the end of your current billing period.

Tsuikey isn’t here to blame anyone for forgetting. It’s here to take on the uncomfortable job of following up, so the people in your life don’t have to.
