Start Learning


We believe that people are the most important part of the learning experience. With this in mind, we envision a world where people learn new vocabualry through their own unique experiences.

A bit of ML magic

We start with people at the center of the learning process and combine this with a little bit of machine learning (ML). We also know that an algorithm is not always the best answer.

The right timing

To best learn, we need to discover the moments that matter most without being too monotonous. In this case, we use spaced repetition to make sure vocabulary learning is most impactful and lasting.

“Do you know what a foreign accent is? It’s a sign of bravery.”


Frequently Asked Questions

What does Private Beta mean?

Private Beta is a way for you, as an early adopter, to try out a new product. It’s also a way for you to provide valuable feedback as well as a way for us to rapidly iterate on the near production-ready version of the app.

What do you do with my photos?

Unlike most apps, Hello, World! works entirely on your phone and your photos never leave your device. To support the creation of learning material, we give each photo a unique identifier consisting of a string of numbers. We never see your photos.

What do I need to get started?

Are you actively learning a language?

If the answer is “Yes” and you have an iPhone, then our Private Beta is perfect for you. Join the private beta to get started 👉

Where can I provide feedback?

We thrive on user feedback and expect it for those in the Private Beta. That being said, when you have the Hello, World! app up and running, you can provide feedback directly through the app.
