Slomi: Slow Motion Video

Make any video slow motion or fast motion. Pick a clip, pick a speed, save — Slomi changes the speed without re-encoding the picture, so the result keeps the original quality and is ready in seconds.

▸ SLOW MOTION
0.5× or 0.25× for sports, dance, a golf or tennis swing, a jump, splashing water, a pet in mid-air or a dramatic moment for Reels and TikTok.

▸ FAST MOTION
1.5×, 2× or 4× to speed through a long tutorial, a cooking video, a drive, a time-lapse-style walk or a boring part of a recording.

▸ NATURAL SOUND
The audio is time-stretched with its pitch kept, so voices never sound like chipmunks or monsters. Prefer silence? Turn the sound off.

▸ NO QUALITY LOSS
The video stream is copied, not re-compressed: no blur, no second compression. You see the new length before you save.

FREE AND PREMIUM
Free: 0.5×, 1.5× and 2×, 5 exports every day, no watermark.
Premium: unlimited exports plus the extreme speeds 0.25× and 4×. Choose monthly, yearly (with a 3-day free trial) or a one-time lifetime purchase — restore it any time from Settings on the same Google account.

PRIVATE BY DESIGN
• 100% offline — every video is processed on your phone and never uploaded.
• No account, no sign-in.
• Files are picked with the system picker, so the app never reads the rest of your storage.
• Results are saved to your gallery and appear in the built-in Library, with Share on the result screen.

Reads MP4, MOV, 3GP, MKV and WebM. Saves MP4.

Recent changes:
1.5.0: Manage Premium right in Settings: see your current plan, switch from monthly to yearly to save more, and resubscribe after canceling. The app now tells you when a payment is pending or declined so you don't lose Premium. Bought Lifetime while a subscription is still active? You'll get a reminder to cancel it so it doesn't renew.
