What Makes OQTA Unique?

OQTA is created with only what’s necessary.


Just tap a button and a sound will be sent.
OQTA makes communication simple.

No more struggle to look for words.
With OQTA you can stay in touch with anyone you care about by just tapping a button.


One-way communication

In OQTA you can’t reply to the sender of sounds.
OQTA will never bother you to reply or wait for a reply.
“Close but not too close” is a key to healthy relationships.


Up to eight people

“Cuckoo” from only the people that
matter is more than just a sound.
It reminds you that you have amazing people who do care about you.


Anonymity makes you imaginative

When you hear a sound, you can’t tell who of your circle members sent the sound.
Imagining who sent you the sound will make you happier than you think.

How Do You Like OQTA?

  • Yoko Kimoto (30s, Tokyo)

    “Now it’s part of our everyday lives”

    I gave one to my 93 y-o grandma and we (her grandchildren and great-grandchildren) send her sounds every day. It seems the “cuckoo” sound reminds her of us. She looks happy when she hears it.
    I think we can think of each other more deeply through this nonverbal communication. OQTA brings people living far away closer. The more you use it, the more meaningful the sound becomes.

  • Toshiaki Okazaki (50s, Germany)

    “It enabled me to express affections words couldn’t describe”

    I called her today. She’s 86. She hadn’t taken a walk for a while, but she told me she’d walked every day since I gave her an OQTA clock. She said she felt as if I told her to walk when she heard her OQTA call.
    OQTA is a great invention. It enabled me to express affections words couldn’t describe. I want more people to try this product.
