GolfDays vs StrokeLens

Daily golf swing practice and form checks are the fastest way to improve your golf swing. GolfDays automatically records only the swing and supports form improvement through instant replay and swing comparison. Do you want to make sure your swing form is correct and stable, but find it difficult to record and check your swing? GolfDays automatically records only the golf swing and automatically plays back the swing immediately after the swing (slow playback and frame-by-frame playback are also possible). In addition, recorded swing videos can be played back continuously and compared. *The number of videos that can be stored per day is limited to ten. Removing the limit is a paid option. GolfDays uses the latest action recognition technology to automatically recognize your swing in the video and record only the swinging part. The swing video is saved at a high frame rate*, so the form can be viewed in detail even when played back slowly or frame-by-frame. *Maximum frame rate depends on device's chip ■ Features - Instant Replay Playbacks recorded swing immediately after you swing - Recording Settings Supports switching between rear & front cameras and zooming - Playback Playbacks recorded swings Supports slow playback, frame-by-frame playback, and note input - Continuous Playback Continuously playbacks a serious of recorded swings - Swing Comparison Simultaneously playbacks two recorded swings side-by-side Supports slow playback, frame-by-frame playback, scaling, and time lag adjustment between videos ■ Supported Devices iPhone and iPad with A12 chip or later ■ Paid Options Remove Quota, for removing the limit on the number of videos saved, is available with three purchase options: a monthly subscription, a yearly subscription, or one-time purchase.

Two swings. One moment. StrokeLens takes two tennis videos from your camera roll and lines them up on the one thing they have in common — the moment of contact. What comes back is a single portrait video: both strokes stacked, playing together at full speed, then again at 0.3x slow motion. No scores. No arrows. No advice. StrokeLens does not tell you what to fix. It puts the two swings side by side at the same instant and lets your own eye do the work. How it works 1. Pick two clips — yours and a pro's, this month's and last month's, or the same shot from two different lessons. 2. Trim each one down to a single stroke with the dial. 3. Tap once. The contact alignment is automatic. Built for the way tennis actually gets filmed • Ordinary iPhone footage — no tripod, no markers, no sensors • Forehand, backhand (one- and two-handed) and serve, with nothing to choose — StrokeLens never asks you which shot it is • Works for pickleball swings too • Different angles, different distances, different frame rates: nothing has to match • Portrait output, ready to post Everything happens on your iPhone Your videos never leave the device — trimming, alignment and rendering all happen on the phone itself. There is no account and no sign-in, and StrokeLens works the same with the phone in airplane mode. Three free comparisons a month Free comes with three marked comparisons a month. Unlock removes the mark and the limit together — one payment, no subscription, on every device your Apple Account reaches.
