What if time had a number that was uniquely yours? Stardate reimagines how you experience time by anchoring it to the most meaningful moment in your personal history: your birth. Enter your date of birth once, and the app calculates your personal stardate β a living number that reflects exactly where you are in your own journey through time. Your Personal Stardate Your stardate has three parts: the year of your life you're currently living, the day of that this year, and the percentage of today that has already passed. At 6:34pm on the 88th day of your 57th year, your stardate is 57088.77. It's a clock, a calendar, and a life odometer β all in one elegant number. More Than Just a Number Stardate also shows you how many days you've been alive, what percentage of your life this year represents, and what infinitesimally small slice of your entire life this single day accounts for. These aren't just statistics β they're perspective. The kind that makes you put down your phone and actually do something with your afternoon. Apple Watch Stardate includes a full Apple Watch app and complication so your personal time is always on your wrist. The complication displays the current percentage of your day β a quiet, constant reminder that time is moving. Stardate is for anyone who has ever felt that the conventional calendar is someone else's way of keeping score.

Never miss a "just a quick thing" again. "I need to grab the laundry in 10 minutes." "I have to reply to that email at 3:00 PM today." "Forgot my 8:00 AM vitamins... again." Itβs not quite big enough for your calendar, but itβs definitely a problem if you forget. We all have dozens of these "micro-tasks" every single day. Tired of clearing old settings on your phone's stock timer? Annoyed by the friction of setting a new alarm every time? Or maybe your current reminder app is so bloated with features that you barely use it? We built JustNotify to eliminate these tiny daily stresses. JustNotify is a minimalist notification timer and reminder app dedicated to one thing: notifying you. It does only one thing, but it does it faster and more seamlessly than any other app. βββββββββββββββββββββββ β 3 Notification Styles JustNotify offers three ways to notify you, designed to fit any situation. Presets Create shortcuts for your most frequent tasks. Simply set an emoji, a title, and a duration, then pin them to your home screen. From there, itβs just one tap to notify your "future self." "Start dinner in 30 mins" "Laundry in 15 mins" "Take meds in 10 mins" We prioritized visual recognitionβone look at an emoji tells you exactly what to do without reading a single word. One-Time Notifications Need a quick reminder for a specific time? "Reply to that message at 5:30 PM today" "Prep for the meeting at 9:00 AM tomorrow" Whether itβs a countdown (timer style) or a specific date and time (calendar style), setting it up is effortless. Recurring Reminders Set it once and forget it. Perfect for building daily habits like: "Drink water every morning at 8:00 AM" JustNotify stays on top of your routine so you donβt have to. βββββββββββββββββββββββ β Perfect for Every Moment Work & Productivity: - Focus Intervals: Use it as a Pomodoro timer. Set a "Break in 25 mins" preset and reset it with a single tap. - Meeting Prep: Get a quick nudge 10 minutes before your next call so youβre never caught off guard. Household & Parenting: - Daily Chores: Getting ready for a bath, flip the laundry, or set screen time limits for the kids. - Smooth Transitions: Use a "5-minute warning" before itβs time to head out the door. Recurring notifications make repetitive chores effortless. Building Your Routine: - Morning Rituals: "Journal with my morning coffee." - Evening Wind-down: "Put away my phone 30 minutes before bed." Build the lifestyle you want, one notification at a time. βββββββββββββββββββββββ β Why JustNotify? In a world of over-complicated apps, we chose simplicity. Most apps today try to do too much. You just want to send a quick notification, but youβre forced to navigate through task management, calendar syncing, and team sharing. The screen is filled with features youβll never use. JustNotify is different. We stripped everything away. We do one thing: notify you. Thatβs it. Simple isnβt inconvenientβitβs sustainable. By removing the friction of complex menus, weβve created a tool youβll actually want to use every day. βββββββββββββββββββββββ β Feature List - Custom Presets: Create unlimited shortcuts with your favorite emojis, titles, and durations. - One-Time Notifications: Set reminders by duration (e.g., "in 5 minutes") or specific date and time (e.g., "today at 5:00 PM"). - Recurring Reminders: Easily schedule daily, weekly, or custom repeating alerts (e.g., "Every day at 8:00 AM"). - Active Notification Tracker: View all your pending notifications in a real-time list. - Full Dark Mode Support: Easy on the eyes, day or night. βββββββββββββββββββββββ "We do one thing: we notify you." Your mind is for having ideas, not holding them. Free yourself from the constant stress of "trying not to forget." Let JustNotify carry the burden for you.
