AppLock by Sensory

App Redesign

AppLock makes it easy to lock apps within your phone keeping data safe from intruders. It is an alternative to PIN/Pattern protection by recognizing your face and voice to unlock apps only for you.


When we were first introduced to AppLock, it was already available on the Play Store with over 50,000 downloads. The technology was there: Sensory Inc., the app's inventor, was founded in 1994 and has put speech recognition into close to one billion products. The main issue was a complex and unflattering interface that this innovative software was wrapped in. We were approached to redesign the entire user experience and user interface to boost downloads and retention.

The first thing we noticed about the initial AppLock interface was an outdated, obscure, 90s' look. Unclear and technical instructions, and a confusing UX sent a unfriendly message "Don't use me, I'm too complicated for you. Grrr…".

One of the initial questions that we wanted to test was either to keep the UI on the dark side or bring it to the light. We conducted A/B testing online with over 60 subjects providing light and dark versions of the same screen for their preference. 71% responded in favor of the light version of the screen.

The main objective of our design team was to make AppLock seem as if it was a default Android feature rather than a separate app.

The most crucial element of the redesign was the unlock screen. Visual guides instruct users in achieving successful face and voice recognition.


Language in the initial AppLock was a major weakpoint as it was too technical for a broad audience. The lack of descriptions left users confused and not willing to use most features. The tone of the new app is more friendly and accessible. Technically advanced settings are provided with icons and short descriptions.

We conducted focus group testing to evaluate the redesigned version. The outcome of testing and the redesign process was summarized in an in-depth case study.
