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. Everything is included: moments from 3 to 8 seconds, every alternate take kept in your Vault, a 48-hour grace window for missed days, weekly and monthly films, unlimited chapters and friends, export to Photos anytime, and cloud backup of every moment. Cancel anytime. Everything you've kept stays. A year from now, you'll have 365 days kept: about 18 minutes of ordinary life you'd otherwise have lost. Start with today - you don't get it back. --- One Last Second is an auto-renewable subscription. Annual: $34.99/year, with a 7-day free trial. Monthly: $4.99/month, no trial.

Your bird life list may already be hiding in your camera roll. Feather Trove privately searches the photo library you already have, finds likely bird photos, and suggests species on your iPhone. No choosing photos one at a time. No uploading them to an identification server. With Feather Trove, you can: • Scan your photo library for likely bird photos • Review on-device species suggestions and make the final call • Build a personal life list from years of forgotten sightings • Explore where your bird photos were taken on a private map • Group sightings into bird walks • Confirm, correct, or remove uncertain matches • Create and share polished bird cards • Export your life list as a CSV file Bird detection and species suggestions run on device. Photo dates and locations can refine suggestions locally when available. Original images remain under Apple Photos permissions, and Feather Trove does not upload your photos. Species suggestions may be incorrect and should be reviewed. Subscription note: Most Feather Trove functionality requires an active subscription. Without a subscription, you can view only four summary counts: detected species, photos, mapped photos, and photos needing human review when the classifier cannot decide between two likely bird species. Feather Trove offers weekly and annual auto-renewable subscriptions. Payment begins when you confirm your purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. You can manage or cancel in your App Store account settings.
