About Pepper Networks

Pepper Networks is a 2-person indie development company that designs and builds the Timebox Movie Maker 3D app for iOS, iPadOS and macOS.

Affordable and easy to use Timebox has an intuitive UI with a minimum number of controls and gestures that take advantage of the standard ways of doing things.

We believe in user privacy and security. We do not access or collect any user data. Our use of iCloud provides the best security available. Timebox is as secure as iCloud is. No log in and password required, just an iCloud account.

Timebox is designed to be used by everyone. Other apps in this space are complex, difficult to use, require high-end hardware, time to learn and are not collaborative.

Len Kawell developed the native efficiencies and simple innovative user experience that helps users make collaborative multi scene movies with just a few taps.

Founded in September 2011 by experienced entrepreneurs Mary Ellen Heinen and Len Kawell. The company is headquartered in Kirkland, WA.
