We’ve got great news!

We are excited to announce the brand new Koko Signs app! This has been a passion project for the Koko team for a while now. After partnering with the incredible team at ArcTouch it is finally ready.

Please watch the video for a preview of the app.

Thanks to your donations and a contribution from ArcTouch, the first version of the app has been completed.  Koko Signs version 1.0 includes:

However, we need to raise additional funds to enhance and maintain the app going forward, so that Koko’s legacy continues to generate benefits for great apes worldwide!

As a special incentive, we are offering a pre-release of the Koko Signs app to everyone who makes a donation to The Gorilla Foundation today of $25 or more!



Donate now and we’ll send you a link in advance of the general release of the Koko Signs app (which is planned for December 1, 2023) to be the first to sample the new app. You will also be a part of a select group of people whose feedback we’ll collect and incorporate in the next update, to make the app better for everyone.

Thank you for helping us get this far — we are very close to making the “Koko Effect” (interspecies communication and empathy) just a few clicks away for anyone with a cell phone, from the US to Africa and everywhere in between — with your support!

Wishing you Koko-Love,


Conservation through Communication
