Read on e-ink, not on glass. ReadIsland sends articles, notes, and long reads from your iPhone straight to your Boox e-reader. Paste or share, tap once, and it opens on your Boox — no cables, no accounts, no clutter. The pieces you mean to read pile up all day: the long essay, the careful argument, the story someone spent a month writing. They wait in a tab, then a folder, then a quiet sense of guilt. ReadIsland is where they finally land — on a calm grey page, easy on the eyes, the way long-form was meant to be read. WHY YOU'LL LOVE IT • One-tap delivery — share or paste, then send. It appears on your Boox automatically. • Made for e-ink — no glow, no blue light, no notifications pulling at your attention. • No account needed — pair your Boox once with a 6-digit code. That's the whole setup. • Private by design — your reading is yours. We never collect what you read. • Sends in the background — keep reading while the next piece arrives. HOW IT WORKS 1. Install ReadIsland on your iPhone and the companion app on your Boox. 2. Pair once with the 6-digit code shown on your Boox. 3. Share any article to ReadIsland, or paste text, and tap Send. 4. It opens on your Boox, ready to read tonight. Send it now. Read it later, when the hour is quiet and the screen has stopped asking for anything. —————————— ReadIsland Pro (Auto-Renewable Subscription) Subscribe to Pro to deliver documents to your Boox / E-ink reader without limits — the free tier's 30-deliveries-per-month cap is removed.
