The lines you underlined shouldn't disappear into an app you never open again. Booko turns the highlights scattered across Kindle, Apple Books and every other reading app into cards you can actually browse — so the sentences that once moved you get seen again. And you can write down your own thoughts, ideas and journal entries too — what you read and what you think, kept in one place. WHY BOOKO Most highlights die where you made them. Booko gives them a shelf. No setup, no system to build. Import once, then browse, revisit and share. IMPORT YOUR HIGHLIGHTS Bring in highlights, excerpts and notes from Kindle (My Clippings) and Apple Books. Import once, browse forever. Book covers are matched automatically. Reading in Chinese? WeChat Reading, Dedao, Douban Read and iReader are supported too. CARD BROWSING Every highlight becomes a card you can flip through. Change the background, typeface, palette and layout until each passage looks the way it reads. RANDOM REVISIT Open Booko and run into a sentence you'd forgotten. It might come from a book you finished years ago — or answer exactly what today feels like. COVER WALL & SHELF Browse your library by cover. Multi-select, select all and batch delete keep things manageable even after a large import. NOTES & THOUGHTS Beyond organizing imported highlights, write down your own thoughts, ideas and journal entries anytime — no book required. Edit any single entry; multi-select and batch actions included. HOME SCREEN WIDGET Put a random highlight on your Home Screen. Choose which book categories it draws from, and how often it changes. No need to open the app at all. SHARE IN ONE TAP Export any excerpt as a finished card image for social, or save it to Photos. Markdown export is there too, if you'd rather pipe everything into your own notes system. MAC AND IPHONE Booko is now on Mac. One purchase covers iPhone, iPad and Mac. Organize on the Mac, revisit on your phone. ICLOUD SYNC Turn on iCloud sync and your books, notes and preferences follow you across devices. The line you underlined on your phone is already waiting on your Mac. WHO IT'S FOR - Readers who highlight a lot and revisit almost none of it - People who collect sentences - Anyone who wants reading notes as cards, not as homework - Anyone tired of heavy note-taking apps DESIGN Booko is small on purpose. Reading notes don't have to become tasks, a knowledge base, or a system. Some sentences only need to be seen again, slowly, once in a while. Import once. Browse often. Keep enjoying them.

ReadyTimer is the simplest way to make sure you leave on time. Just enter the time you need to leave — or how many minutes you have — and ReadyTimer will announce the time remaining at your chosen interval. No more losing track while you're getting dressed, packing your bag, or doing your hair. HOW IT WORKS • Set your departure time or choose how many minutes you have • A voice announces the time left every 1, 2, 3, 4, or 5 minutes • When you're out the door, tap "I'm Out" (optional) to mark it as on time WHAT IT SOUNDS LIKE "Hey, you've got 15 minutes to get ready. Let's go!" "10 minutes left — how are you doing?" "3 minutes left. Wrap it up!" "1 minute! Out the door!" KEEPS ANNOUNCING EVEN WHEN YOU SWITCH APPS ReadyTimer runs in the background — so you can scroll, check messages, or play music and it will still announce your time out loud. It even plays over your music or podcasts without interrupting them. VOICE PERSONALITIES Choose from multiple AI voice personalities — from cheerful and encouraging to no-nonsense — so your reminders actually feel good to listen to. PRESETS Save your recurring routines as presets. One tap and you're ready to go. TRACK YOUR STREAK Every session is recorded in your history. See how many times you made it out on time and track your streak on the scoreboard. Nothing motivates like seeing your own data. ReadyTimer is for anyone who knows exactly when they need to leave but somehow always ends up rushing anyway.
