Slow motion video analysis in a fast paced world! Use this app to time actions that occur in minute moments of time. Simply use Slow-Motion mode in the Camera app then switch to this app and analyze your video frame by frame with time stamps accurate up to 1/100th of a second! View the waveform of the audio for increased prevision or use keyframes to automatically calculate the duration of an event. Simply set the keyframe at the beginning of the period and advance the video to the end of the event. Your time delta will be automatically calculated. ## Key features - Frame-by-frame analysis - 1/100th second timestamp accuracy - Slow-motion video support - Audio waveform visualization - Automatic event duration calculation - Keyframe functionality ## Pricing and in-app purchases Base price: $0.99. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Remove Ads | $1.99 | one-time | ## Recent user reviews (7 of 7) All indexed reviews: https://appshunter.io/ios/app/frame-timer/id1023278352/reviews.md ### 5/5 — Perfect for what I needed *2026-01-10* I needed a simple app to measure subsecond timings when speed lifting and this does the job perfectly. I tested it first against a stopwatch and it seems completely accurate, tracking my stopwatch accurately to 1/100th of a second over the several seconds I tested it for. ### 2/5 — Not terrible for the price *2024-08-25* It seems to be kind of buggy? There’s a loading spinner in the middle that never resolves, when I’m trying to go through frames one by one it’ll sometimes start *playing* and there’s no way to make it stop expect to close out and reopen, thus losing your place. It’s also a pain that you can’t jump to a particular frame or move a slider or something to go through frames faster than one-by-one. That said, it still *basically* does what I want—let me view frames in a video one at a time, flip forward and backward through them one at a time, and it tells me both what frame # I’m on and what the time stamp is. It’s fair for the price. ### 5/5 — Exactly what I was looking for *2020-05-19* In my work I need to measure some things that happen far too quick for me to see. So I take slow motion video and try to eye ball it. At my last job I had a high speed camera for these measurements, that I don’t have anymore since changing jobs. With this app I’ve been able to get incredibly close to the measurements I’m after. Hope you continue to keep this app up to date, it works great. Features I still wish it had was a scrubber for video position so I can drag to the right point of the video. A play and pause button. And single frame advance and rewind. ### 1/5 — Garbage, does not even open. A complete scam. *2019-11-28* Don’t buy this, it won’t even open. Apparently a complete scam. **Developer response:** Hi Brad! Sorry to hear that, we'd love to make this right. Can you shoot us an email at info@rybel-llc.com? ### 1/5 — Garbage *2019-08-15, version 2.0.0* I paid for this app and yet there are still ads. Total crap. ### 5/5 — I used this for my physics I.A *2019-04-05, version 2.0.0* This app was very helpful when I was completing my final paper for physics 35 IB higher level. The only suggestion I would have is for the user to have a faster method of finding a point in the data, like a video scroll bar. ### 1/5 — Crashes *2019-03-02* Cannot load a video. Gets as far as selecting and a progress bar which says “compressing video” and then the app crashes. ## Frequently asked questions about Frame Timer ### What is Frame Timer used for?
