DotInk
ePaper Font Converter
QAR 7.99 · Designed for iPad
An all-in-one tool for adjusting, previewing, generating, and pushing fonts!
Convert your favorite fonts for your portable e-ink readers — right from your phone.

Key Features:
1. Use system fonts or import external .ttf font files.
2. Customize character spacing, line height, size, and weight for better readability on your e-ink display.
3. Preview font rendering in real time — closely simulating the actual e-ink device display.
4. Supports multiple portable e-ink readers, including XTEINK X4, MoFei 3.7, and WuDaDa·XiaoMo.
5. Added support for interaction with e-ink devices, such as pushing fonts directly to the device. (Currently supported: ReadStar X4)
Designed for readers, creators, and developers who value clarity and simplicity.
Thank you to all our early supporters — we welcome your feedback, ideas, and suggestions!
Ratings & Reviews
This app has not received enough ratings or reviews to display an overview.
1. New “Push to Device” feature
You can now directly push generated font files to your e-ink device within the app — all in one step.
(Currently supported: ReadStar X4; more devices will be supported in future updates.)
2. New “Simplified ↔ Traditional Conversion” feature
Automatically maps Simplified Chinese Unicode code points to Traditional Chinese.
Even if your text is in Simplified Chinese, the converted font will display Traditional Chinese glyphs on the device.
3. New “English Paragraph Preview” feature
You can now preview how English paragraphs look after font conversion.
Please note that due to format limitations on some devices (.bin rendering constraints), precise word and letter spacing cannot be fully replicated — the preview may slightly differ from the actual device display.
4. UI and interaction optimizations, plus various bug fixes
