Built for hands-free moments
We design controls that reduce repeated touch gestures and make long screen sessions easier to manage.
Small tools, clear purpose.
We focus on lightweight mobile software that solves one real problem well. Our products are designed to be simple, privacy-conscious, and useful in ordinary daily routines.
On-device first
Where possible, sensitive signals are processed locally on the device instead of being uploaded to a server.
Made for real use
We test around lighting, device distance, battery, heat, and the small frictions that appear in daily use.
