Time Flies

Oh how Time Flies! Stop wondering where it went. Yesterday it was the new year, and before you realize it's Thanksgiving already. Time Flies is a reminder and planner app that keeps you plugged in to the passage of time — what is coming, what has passed, how long ago and how long to go. That number is the whole point, and every part of the app gives it to you. SPAN - YOUR WHOLE LIFE ON ONE RULER (Pro) Today sits in the middle, the past on the left, the future on the right. Drag and the number climbs — 15 days, 62 days, 3 years. Zoom out from a week to a whole year and the shape of your life appears: busy weeks stand tall, quiet months are gaps you can see from across the room. Tap anything for how long ago it was, when it comes round again, and how many times it already has. COUNTDOWNS THAT WORK BOTH WAYS 37 days to your trip. 8 months since you moved to a new city, or started a new job. Both sit at the top of your home page, so nothing sneaks up on you. Tap any event, task, reminder or memory and start counting to it — including the next time a birthday comes round. A countdown retires itself the morning after it lands, so your list never fills with things that already happened. WHAT YOU CAN PUT IN IT Six color coded types of activity... REMINDERS - for something you want a quick one-off notification for. TASKS - for something you want to do and tick off. Anything you don't finish rolls over to today and shows how many days it has been slipping. EVENTS - for something happening at a specific date and time. MEMORY - for something worth keeping. Time Flies counts the years for you and tells you when the anniversary comes round. ALARM - for something too important to sleep through. It cuts through Focus, and on iOS 26 and up it takes over the screen like a proper alarm. COUNTDOWN - for something you want to watch approach, or keep counting once it has passed. JUST SAY IT Type "dentist Friday at 2" or just talk to it. The AI assistant knows your routine — wake up, lunch, family time, wind down — so new plans land where your day actually has room. Ask it to move things, ask what your week looks like, ask it anything. Tap the mic on your home screen and speak once (Pro). Or share a flyer, screenshot or voice note in from any other app, add one line of context — "I want to go next week" — and it becomes a plan. A DAY YOU CAN READ AT A GLANCE One clean timeline, color coded by type and framed by your own routine. A home screen widget keeps today and your nearest countdowns one glance away (Pro). ON THIS DAY (Pro) The memories you logged, brought back on their anniversary, right on today's timeline. Never more than a few, and only the ones worth returning to. ON THE HORIZON Anything coming up appears well ahead of time, then again as it gets closer — six months out, then a month, a week, the day before. Nothing arrives without warning. EVENING PROMPT AND DAILY OVERVIEW (Pro) A quiet nudge at day's end: anything worth remembering from today? One line is enough. And each morning, a short brief on the day ahead, including what rolled over. WEEKLY REWIND (Pro) Every Sunday evening, a short warm recap of where your week went. YOURS, EVEN OFFLINE Saves without a connection and syncs when you are back. Your memories are yours — mute any memory, any person, or the whole feature in one tap. FREE TO START Everything above is free except where marked Pro. Every activity type, countdowns, routines, notifications, rollover and offline saving are free forever. You also get five AI requests free — not five a month, five for life — to try the assistant before deciding. Pro unlocks unlimited AI scheduling, Span, home screen voice capture, the widget, On This Day, the Daily Overview and Weekly Rewind. A subscription auto-renews unless cancelled at least 24 hours before the period ends. Manage or cancel anytime in Settings. https://sotimeflies.com/terms https://sotimeflies.com/privacy Time flies either way. Keep it.

Verdict
The clearest difference is in-app purchases: SpillStack at none against Time Flies's 2. SpillStack also leads on update cadence (daily vs every 10 days) and device support (3 vs 1). On price, ads and iOS requirement there is nothing between them.
