Adagio: Slow Mo & Smooth
Slow motion video, on-device
Free · In‑App Purchases
Smoother motion and clean slow-motion for your videos. Everything is processed on your device — your footage is never uploaded.
Adagio improves the motion in your videos: movement becomes continuous and a chosen moment slows down without stutter. The app builds the frames between the ones you shot, so motion flows and slow-motion stays calm.
All processing happens on your device. Your video is never uploaded — neither to process it nor to store it.
TWO EFFECTS
• Slow motion — clean slow-mo for the whole clip or only for the moments you pick: 2×, 4× or 8×.
• Smooth — continuous movement: up to 8× the frames, as far as the source frame rate allows.
SEE IT, THEN DECIDE
• The finished video opens at once and plays by itself; fullscreen is one tap away.
• You can always watch it: once your free videos are used up, it opens in full with the Adagio mark, so you decide whether to save only once you have seen the result.
IT FITS YOUR DEVICE
• Two plain choices: Best quality or Faster. The app decides the rest.
• An honest section on where smoothing is harder: fast motion, scene cuts, fine detail.
ON YOUR DEVICE
• Works without an internet connection. Your video does not leave the device.
• A privacy section that states what leaves the device and what does not.
IPHONE, IPAD AND MAC
• One app for all three, one shared purchase.
WHAT IT COSTS
• One video free. After that, a single one-time purchase, no subscription. A clip that already used a free video can be re-processed as often as you like without using another.
Adagio does one thing well: it improves motion by building frames. It does not denoise, sharpen, upscale or stabilize your footage.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• If processing fails, Adagio tells you what happened and what to do. If your device runs low on memory, processing no longer stops — it carries on at slightly lower quality.
• If you leave the app while a video is processing, it stops and offers to start again — a broken video is no longer saved as finished.
• On iPhone, the bottom panels — saving, renaming, purchase — now reach all the way to the edge of the screen.
• On Mac, Adagio no longer asks for your keychain password at launch if a test version was installed before.
• Crash reports are more detailed: they include the screen and your last steps in the app — no video and no personal data. Details are in the Privacy Policy.
