Capture Every Perspective in One Take Stop choosing between TikTok and YouTube. Dual Recorder: Both Aspect Videos is the ultimate tool for content creators who need to be everywhere at once. Leveraging advanced multi-camera processing, this app allows you to record vertical and horizontal video simultaneously, saving you hours of editing and ensuring you never miss the perfect shot in either format. Whether you are capturing a cinematic landscape for your vlog or a high-energy portrait clip for your social feed, Dual Recorder: Both Aspect Videos handles the heavy lifting. One session, two separate files, zero compromise. Key Features Dual Format Recording: Record in 9:16 portrait and 16:9 landscape at the exact same time. The app generates two distinct high-quality video files from a single recording session. Dual Lens Integration: Utilize different lenses on your device to capture the widest field of view for landscape while maintaining a focused portrait frame. Single Lens Mode: Even in single lens mode, the app uses intelligent cropping and sensor utilization to provide both formats instantly. Pro-Grade Controls: Take full command of your output. Adjust resolution (up to 4K), frame rates (24, 30, or 60 fps), and file formats (MOV or MP4) to match your workflow. Instant Export: No more cropping or stretching in post-production. Your videos are saved to your library ready for immediate upload to any platform. Visual Guidance: Integrated on-screen overlays show you exactly what is being captured in both frames, so you can compose your shots perfectly for every destination. Why Dual Recorder: Both Aspect Videos? Modern social media demands multiple formats. Traditionally, this meant recording twice or losing significant quality by cropping a horizontal video into a vertical one. Dual Recorder: Both Aspect Videos solves this by maximizing your iPhone sensor's potential, giving you professional results for Reels, Shorts, and traditional video platforms simultaneously. Note: Some features, including 4K recording, high frame rate options, and advanced dual-lens configurations, may require a paid subscription.

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 review sentiment: One Last Second at 100% against Dualsy's 7%. Dualsy's advantage is ads (none vs shown) and ratings volume (307 vs 11). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Dualsy sells 9 in-app purchases, starting at $4.99 per 7 days and One Last Second sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Dualsy holds the better App Store score, 4.3 against 4.1. That said, the two scores are not equally well evidenced: Dualsy has 307 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 7% of Dualsy'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

Dualsy ships an update every 3 days, One Last Second daily. Both last shipped on October 25, 2026.
