Ninety seconds to know. The rest of your life to act.
If you see your parents four times a year and they're in their sixties, there are roughly sixty visits left in the whole relationship — not a lifetime, a few dozen weekends.
49 Sundays just shows you the number. One name, one age, one slider. The answer comes back in the unit that hits — visits, seasons, Sundays, mornings — and a share card beautiful enough to actually send.
Three screens. You can do this at a red light or in the car home from Thanksgiving.
That's all. No login, no email, no onboarding carousel.
The unit adapts. 52× a year is "Sundays." Daily is "mornings."
9:16 share sheet for Story, iMessage, WhatsApp, or just your camera roll.
The unit depends on how you share your life. A weekly Sunday dinner is fifty lunches. A daily morning is five thousand coffees. The math bends to match reality.
Three people free. Five bucks for everyone else in your life. No subscription, no trial, no renewal.

SSA Period Life Tables 2021. Every number prefixed with "~".
Not a medical tool. Makes no claims about your lifespan.
Nothing in the cloud. No account. Nothing to delete.
A few things people ask us most. Short answers below; the longer story is on the App Store page.
Yes — free for up to three people. A one-time $4.99 unlock lets you calculate for unlimited people. No subscription, no trial, no renewal. Pay once, yours forever.
It uses U.S. Social Security Period Life Tables (2021) — population averages, not predictions about any individual. Every number is prefixed with a tilde (~) to remind you these are estimates. Individual lives vary widely.
No. After install, the calculator runs entirely on your iPhone. Nothing is sent to a server, and no connection is needed to calculate or view share cards.
None. No account, no email signup, no cloud sync. The names, ages, and visit frequencies you enter stay on your iPhone and can be deleted any time.
By how often you see them. Once a year is visits. A few times a year is seasons. Weekly becomes Sundays. Daily becomes mornings. The app picks the unit that lands emotionally so the number is something you can feel.
It's about spending time, not predicting death. The app makes no medical claims, uses population averages only, and surfaces a crisis hotline (text HOME to 741741) for anyone struggling. A lifestyle app inspired by Tim Urban's "The Tail End," not a health tool.
A solo project by DungMai, an indie developer based in Saigon, Vietnam. The app launches on Product Hunt on Tuesday 16 June 2026, the day before Father's Day.
I'm DungMai, an indie developer in Saigon. I read Tim Urban's The Tail End in 2015 and never quite recovered from the math. 49 Sundays is the smallest possible version of that essay — one screen, one slider, one honest number — built so the people in my life (and yours) get a few more Sundays out of the time we actually have left.
No account, no cloud, no subscription. Five dollars if it sticks. Free if it doesn't.

Ninety seconds to know. Five dollars to keep counting. Yours forever.
