BlahBlah - Message Your Future Self Because some things are only worth saying to yourself. # Sound Familiar? You send links to yourself on WhatsApp. You text an idea to your own number before it disappears. Millions of people do this every day — in apps never quite designed for it. BlahBlah is what that habit always deserved. # What is BlahBlah? BlahBlah is a self-messaging app for iOS, built around the familiar comfort of a chat interface — except every message is from you, to you. Not a journal. Not a note-taking app. Not a to-do list. A chat. With yourself. # What You Can Send A thought doesn't always arrive as words — so send text, images, voice memos (with on-device transcription), links with rich previews, locations, and Apple Music cards. # Capture From Anywhere See something worth keeping in another app? Tap Share to send text, links or photos straight into BlahBlah. BlahBlah controls live in Control Centre, the Lock Screen and the Action Button — one tap to a note, voice, photo, link, music or location. A Quick Capture widget and Siri & Shortcuts capture without even opening the app. # Two Voices, One You Sometimes the clearest thinking isn't a monologue. It's an argument. Dialogue mode splits the conversation into two sides — rational and emotional, question and answer. Set names and avatars for each role, then start talking. # Write to a Past Moment Backdate records a message to an earlier date and time — yesterday's forgotten note — then drops it where it belongs in your timeline. A Premium feature, from the "+" menu or Control Centre. # Start From a Template Save what you write again and again — a daily rant, a morning check-in — as a template with its tags, and start from it in one tap. With Premium, reminders open the right template at the right time. # Look Back BlahBlah helps you return to yourself: • On This Day — what you wrote a week, a month, even a year ago. A banner surfaces it, or a daily reminder brings it to you. • Daily Reflection — a gentle question to look inward, fresh each day. Open it from a widget, reminder or Control Centre; your answer keeps the question with it. • Streak — a Home and Lock Screen widget counting your days in a row, current at a glance. # Find Your Past Self Search and browse your whole history: Search by keyword, browse by type — every photo, location and link — or filter by date range, tag (Starred, Idea or your own, AND/OR), template and dialogue role. Tap any result to jump back to that moment. # Keep It Just Right Long-press any message to edit it in place. Edited messages are automatically tagged so you can find them again. # Make It Yours This conversation is personal — so make it look right: • Five bubble themes, from Classic Blue to Sakura Blossom • Plus message alignment, timestamp frequency, corner style and bubble tail # Free vs Premium Free covers the everyday — text, photo, link, location and music messages, editing, resending, a template, On This Day, iCloud sync, and a 20-message taste of Dialogue mode. Premium unlocks voice memos with transcription, up to 9 photos a message, unlimited Dialogue mode, 10 custom tags, 20 templates with reminders, place and music search, full search history, batch actions, and every personalisation option. # Private & Everywhere BlahBlah syncs across all your Apple devices via iCloud — no account, no server, no analytics, no third parties. Everything stays between you and your devices. Your inner monologue is yours alone. BlahBlah — Say it. Save it. Come back to it.
