About
Turn choppy video into buttery-smooth motion — with one tap.
FlowFrame uses AI frame interpolation to draw the frames your video is missing, turning it into smooth 60fps / 120fps footage or 2x / 4x slow motion. Everything runs on your iPhone. Your videos are never uploaded.
GREAT FOR
• Choppy gameplay captures and anime clips
• Pets, kids, dance and sports — add slow motion after the fact
• 30fps footage that deserves to look great on a 120Hz display
• A final polish before posting to social media
THREE SIMPLE STEPS
1. Pick a video (Photos or the Files app)
2. Choose 60fps, 120fps or a slow-motion factor — FlowFrame shows the resulting fps, duration and frame count up front
3. Tap "Make it smooth" (progress and time remaining shown; cancel anytime)
Then compare Before / After / Split slider, and save to Photos or share.
WHY FLOWFRAME
• 100% on-device — no uploads, no account, works offline
• On iOS 26 and later, Apple's latest frame-rate conversion technology delivers higher quality and speed
• HDR stays HDR — brightness and color don't shift (converted to SDR on some devices)
• No watermark — not even on the free version
• Your original is never touched — a new video is added to Photos only when you save
• If a video can't be converted, FlowFrame tells you why (unsupported format, low memory, low storage…)
FREE
• Convert the first 10 seconds of any video (longer clips are trimmed so you can try it)
• 60fps output, up to 1080p
• Slow-motion (2x / 4x) preview
• Before/after comparison and saving to Photos
PRO — ONE-TIME PURCHASE, NO SUBSCRIPTION
• No length limit — convert to the very last second
• 120fps output
• Save and share slow motion (2x / 4x)
• Output up to 4K
• High-quality export (more accurate in-between frames + higher bitrate)
Buy once, keep forever. PRO is tied to your Apple ID and can be restored on a new device.
COMPATIBILITY
• iOS 16.4 or later
• Input: videos from Photos or the Files app (MOV / MP4, etc.)
• Output: 60fps / 120fps, 480p–4K, HEVC (H.265)
PLEASE NOTE
• Frame interpolation estimates motion, so fast or complex scenes may show some ghosting or warping
• 4K and long videos take time. Keep the app open and the screen on while converting
