Your life has about 4,000 weeks. One Last Second is a daily practice for noticing them. The entire app is one constraint: capture one 3-second video each day. At midnight, it seals forever. No edits, no do-overs, no backfilling from your camera roll. That's not a missing feature - it's the whole point. When today is the only day you can capture, you start paying attention to it. THE PRACTICE Open the app, record a moment, done... under a minute a day. Every Sunday evening, watch a short film of the week you just lived. On the first of the month, watch the whole month. Anniversaries resurface with On This Day. And your life grid, one dot for every week of your life, slowly fills in, captured weeks glowing white among the rest. MEMENTO MORI The app is built in an old tradition: remember that you will die. Not morbidly - clearly. A live countdown to midnight. Your weeks, counted. Daily lines like "2,912 Sundays remaining." It sounds heavy. In practice, it's the opposite: it makes ordinary Tuesdays feel worth filming. NO SHAME FOR GAPS You'll miss days. That's part of it. Empty dots are part of your story. There are no streak-shame mechanics here, and the only failure is never showing up again. NO NOISE No AI. No ads. No algorithms. No strangers. Nothing to fill in: sign in with Apple in one tap, and your archive outlives your phone. If you want, invite your close friends and family into a private circle and share your one last seconds. ONE SUBSCRIPTION One Last Second is a subscription: $34.99 a year with a 7-day free trial, or $4.99 a month. No free tier, no lifetime plan, no ads.

Verdict

The call

The clearest difference is rating: One Second Day at 4.7 against One Last Second's 4.1. One Second Day also leads on ads (none vs shown) and device support (3 vs 1). One Last Second's advantage is update cadence (daily vs every 5 months) and review sentiment (100% vs 80%). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

One Second Day holds the better App Store score, 4.7 against 4.1. Both are backed by a comparable volume of ratings — 13 and 11 respectively. Written reviews complicate that: 80% of One Second Day's written reviews are positive against 100% of One Last Second's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

One Second Day ships an update every 5 months, One Last Second daily. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
