TeenSync is a private, offline companion for the busiest years of high school. College applications, test prep, habits, and everything you are feeling about it, in one app that never sends your life to a server. COLLEGE HUB Track every school with its own deadline and application type: ED, ED2, EA, REA, RD, or Rolling. Work through a document checklist that shows real progress instead of a wall of unchecked boxes. Keep essays in the Essay Vault, either written in the app or linked out to a document you already started somewhere else. Not sure whether to apply early? The Guide asks three questions and gives you a straight answer. GOAL TRACKER Lay out your Senior Year Roadmap milestone by milestone. Build habits and watch the streaks grow. Log extracurriculars and honors as they happen, then export a clean Common App summary when it is time to fill in the real form, instead of trying to remember sophomore year from scratch. Track test dates, scores, and study sessions so you can see whether the hours are actually paying off. ONE CALENDAR Application deadlines, test dates, and milestones on a single grid. Not four separate calendars that each know one piece of your life and none of the conflicts. SYNC SPACE Journal in text or in your own voice. Seal a letter to yourself and choose the date it opens. Watch a year of your moods fill in as color on the Mood Map. Build a vision board and a memory grid in My World. Or start a Sync Session: pick a breathing pattern, breathe through it, answer three short prompts, and get a mix built from your answers. Nothing is saved unless you ask for it. PRIVATE BY DESIGN TeenSync has no account, no sign in, and no networking code at all. Your entries, essays, voice memos, and photos stay in the app on your phone. Nothing is uploaded, nothing is tracked, nothing is sold, and no one is building a profile of you. The only time anything leaves the app is when you tap share yourself. Built for students who are tired of being the product. Credits: 2.0 Developed by Savia Thomas www.TeenSync.org
