Change the speed of videos. Make them faster or slower. Download the Video Speed Changer app for free now! With this app, you can change the speed of videos and adjust the playback speed. Make your videos faster for timelapse, Timewarp, or Hyperlapse effects, or slow videos down and turn them into slow motion. Just open the video in the app and change the video speed in a few simple steps. The app works with videos recorded on iPhone or iPad, and also with videos from external cameras such as drones, action cams, dash cams, or other cameras. Common video formats like MP4 and MOV can be made faster or slower afterward. If you recorded a long clip while driving down a road, for example, you can simply speed up that video and create a time-lapse. Or if you have a video of someone that you want to slow down, you can turn it into slow motion later. If you are wondering how to speed up a video, accelerate a video, slow down a video, turn a normal video into a time-lapse, or change the playback speed of a video on iPhone or iPad, the Video Speed Changer iOS app is made for exactly that. Tip: If you want to create a funny video, try this: Record a video of someone speaking in front of the camera. Slow the playback speed down to 0.5x with the app, and it will sound as if the person is drunk. A simple slider and preset buttons make it easy for anyone to create slow motion or time-lapse from an existing video. Just open the app, choose a video from your iPhone or iPad, and drag the slider to the right to make it faster or to the left to slow it down. This lets you change the playback speed of your video without using complicated video editing software. In the editor where you adjust the video speed, there is also a preview feature. You can see the original playback duration of the source video and the new duration after your selected video-speed change. The finished video is saved without a watermark or logo. The original video resolution is preserved: 1080p videos stay 1080p, and 4K videos stay 4K. This lets you change the speed of your video without reducing its resolution or quality. Videos are processed securely and privately, only locally on your own device. There is no upload to the cloud or to external servers. This is ideal if you want to edit videos privately and directly on your iPhone or iPad. The finished changed video can be saved and sent via iMessage, WhatsApp, or other messengers, or shared on social media such as Facebook, Instagram, TikTok, Snapchat, Instagram Reels, YouTube Shorts, Stories, or Status.

Verdict
The clearest difference is rating: Video Speed Changer at 4.7 against MemoLens's 3.7. Video Speed Changer also leads on ratings volume (1.4K vs 6).

Both are free to download. Video Speed Changer sells 7 in-app purchases, starting at $1.99 per 7 days. MemoLens asks for nothing beyond the download.
Video Speed Changer holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: Video Speed Changer has 1.4K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 34% of Video Speed Changer's written reviews are positive against 67% of MemoLens's, so the app with the better star average is not the one people write more warmly about.
Video Speed Changer ships an update every 5 months, MemoLens every 3 weeks. The most recent releases landed on November 11, 2026 and November 4, 2026 respectively.
