Sebastian — Daily Assistant Sebastian pulls your calendar, reminders, notes, alarms and timers into one place, and keeps them tied to the people they are actually about. THREADS Link a calendar, a reminder list, a note, an alarm or a timer to a person, and Sebastian builds them a thread — one timeline of every appointment, reminder, note and comment involving them. Filter it to one kind of entry, then share it as text or a formatted PDF. It is the fastest way to answer "what has been going on with Mum's care?" without digging through four apps. YOUR DAY • Today: events, due reminders and what needs attention, in a dashboard you arrange yourself. • Reminders: group by list, due date, priority or status. Save Quick Views, act on many at once, and timebox a task straight onto your calendar. • Calendar: day, week and month, with conflict spotting and travel time. • Notes: Markdown, images and attachments, with their own widgets — and with Plus, Notes on the web: read and edit them in any browser, synced through your own iCloud. TIMERS, ALARMS AND FASTING Multiple named timers, full alarm scheduling, and fasting timers that keep running past their target so you can see how long you actually fasted. WIDGETS AND SHORTCUTS Home Screen, Lock Screen and StandBy widgets, launcher cards, Live Activities, Control Center controls, Spotlight search and Siri Shortcuts. DRIVE MODE A large-type, glanceable view of what is next when you are on the road. PRIVACY Your calendar, reminders and contacts stay on your device and in Apple's own apps. Sebastian asks for what it needs and nothing more. There is no account and no sign-up. FREE AND PLUS Free shows every calendar and reminder list you have — nothing is hidden. You can add to and edit any three of each, and tick off or delete a reminder wherever it lives. It includes alarms, timers, severe weather alerts, and the small and medium widgets. Sebastian Plus is a single one-time purchase — no subscription, nothing to renew — and it lifts every limit: editing in all your calendars and lists, unlimited notes, sync across your devices, Notes on the web, full thread history and export, hourly and 10-day forecasts, focus timers, shared tags and the large launcher widgets. It is shareable with your Family Sharing group. New installs get 30 days of everything to try first. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

When did you last change the air filter? Water the succulents? Call your mom? Ago answers one question: how long has it been? Tap once to reset. That's it. THE GAP BETWEEN A TO-DO LIST AND A CALENDAR Not a streak tracker. Not a to-do list. Ago lives in the gap between both - for things with a rough cadence you want to honor, not a fixed schedule. Car tires. The dentist. The friend you keep meaning to call. Plants that need water every couple of weeks or so. NO GUILT TRIPS. JUST THE NUMBER. Ago shows you how long it's been and gets out of the way. No judgment. No chain to break. No notifications nagging you. Open it when you want to know. The "three months?!" moment is the whole product. You see the number, you decide what to do about it. ALWAYS ONE GLANCE AWAY - Home Screen and Lock Screen widgets show the live elapsed time, counting up in real time - Log something done right from the widget, without opening the app - A soft deadline turns a card overdue when it's been too long - a quiet cue, never an alarm BUILT TO BE EXACT, NOT FUZZY - See the precise time since you last did it, down to the day - Open any item for a monthly calendar of its history - Give each thing an icon and a color so the list reads at a glance WHAT PEOPLE TRACK WITH AGO - Home maintenance: air filter, furnace, gutters - Plant care and watering - Car service and tires - Medication and supplements - Friends and family: how long since you called? - Pet grooming and vet visits SIMPLE AND PRIVATE No accounts. No ads. Nothing to sign in to, nothing to manage. Your data syncs privately across your devices with iCloud, and stays yours. PAY ONCE. KEEP FOREVER. One-time purchase unlocks everything. No subscription. Ever. Pick a color, choose an icon, set a soft deadline, and Ago tells you when something's been a while. No alarm, no nag. Just a card that says it's time.

Verdict

The call

The clearest difference is update cadence: Sebastian Assistant at every 2 days against Ago's weekly. Sebastian Assistant also leads on monetization model (free with in-app purchases vs paid). Ago's advantage is ratings volume (20 vs 1) and iOS requirement (16.4 vs 18.0). On price, rating, ads and in-app purchases there is nothing between them.
