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.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Focus Field sells 2 in-app purchases, starting at $0.99 per month and Ago sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 5.0 for Focus Field against 5.0 for Ago. That said, the two scores are not equally well evidenced: Ago has 20 ratings behind it against 3, so its average is the more settled of the two.
Focus Field ships an update every 9 days, Ago weekly. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
