About this app

Prexbi helps you read more comfortably when on-screen text feels small, unstable, or strains your eyes.

The app offers an adaptive reading experience for people with presbyopia, eye strain, or difficulty holding a phone screen. It allows you to adjust text size, contrast, use simple mode, and create reading profiles, as well as adjust voice and focus tools to reduce eye effort.

Main features:
- Adaptive reading with lens levels L0-L4.

- Quick A/B comparison reading adjustment.

- Profiles for bed, work, bright light, and night.

- Import text, links, and PDF documents.

- Text-to-speech to continue reading without losing your place.

- FlowFocus to hold the current paragraph.

- Distance and visual comfort assistance.

- On Android, an option to support reading in selected apps via AccessibilityService.

- Device-centric processing.

Prexbi is not a medical device and does not diagnose or replace the opinion of an eye care professional.
