Read late without the glare#
Eye doctors advise keeping your screen about as bright as the room around it. When the screen glows brighter, your eyes work harder[1]. That's every late study session with a white page in a dark room.
In Notesify, when you switch to the dark theme, PDF pages turn dark with light text, like the rest of the app, so nothing on screen glares at you.

The usual
A dark app with a bright white page in the middle.
In Notesify
The page goes dark too, so your eyes stay settled.
No more white flash#
Your eyes settle into a dark screen. Then you open a PDF, or switch back to it from the chat, and a white page lights up the screen. It happens every time, all evening.
In Notesify, PDF pages turn dark with everything else: the toolbar, the page thumbnails and the AI chat beside the page. Opening a file is no brighter than the rest of the screen.
The usual
Every PDF opens as a bright white page in an otherwise dark app.
In Notesify
PDF pages go dark with the rest of the app, so nothing flashes.
Make your battery last the day#
Many phones have OLED screens, where dark pixels use less power. Purdue researchers found dark screens cut display power by 39–47% at full brightness, and by 3–9% at a typical 30–50%[2]. The brighter you read, the more you save.
The usual
Long reading days on a white page drain the phone by evening.
In Notesify
Dark pages use less power, most of all at high brightness.
Your highlights come along#
Darkening the page doesn't cost you your work. Highlights show as a soft tint behind light text, pen notes keep their colour, and charts keep theirs, so a red line still matches its key.
In bright daylight, most people read dark text on a light page more easily[3], so switch back to light pages whenever you like. It's one click.
Turn it on#
In the Notesify app, open Settings and set App theme to Dark, then set PDF theme to Inverted for dark pages. See the step-by-step tip.

No. Highlights show as a soft tint behind light text, and pen notes keep their colour.
