TapLine
Read full descriptionHide full description
TapLine is a reading app designed for people who want to read more but struggle to start โ especially those with ADHD, busy schedules, or a brain that drifts after a few lines. The secret is Single-Sentence Mode. Instead of a full page of text, TapLine shows you just one sentence at a time. Tap to move forward, swipe to go back. It feels like scrolling a feed โ but you're actually reading a book. WHAT MAKES TAPLINE DIFFERENT - Single-Sentence Mode breaks any book into bite-sized pieces, so you can read for 2 minutes on the subway and actually retain it - No overwhelming walls of text โ just one thought at a time - Build a mini-reading habit that fits into your real life - Supports EPUB format so you can import your own books WHO IT'S FOR - People with ADHD or other attention challenges - Busy commuters who only have a few spare minutes - Anyone who buys books but never finishes them - Readers who feel guilty every time they reach for their phone instead TapLine was built by an indie developer with ADHD who got tired of feeling bad about not reading. It's not about reading faster โ it's about reading at all. PRO FEATURES - Unlimited book imports - Full reading history and progress tracking - Customizable font size and display settings Download TapLine and read your first book โ one sentence at a time.
