8Synk overlays beat counts (1–8) on your dance videos, making it easy to review choreography, practice on your own, and create count-synced videos for social media. HOW IT WORKS 1. Choose a dance video from your camera roll 2. Set the BPM (auto-detect, tap along, or adjust manually) 3. Sync the count bar to beat 1 Then just play the video. Counts "1, 2, 3 ... 8" appear right on top, in time with the music. KEY FEATURES - Auto BPM detection, plus tap-in and manual fine-tuning - 3 count bar styles: Line, Band, and Circle. Switch anytime - Drag the count bar anywhere and switch between S and L sizes - Mirror mode to see the choreography facing the same way you do - Slow playback (0.5x / 0.75x / 1x) for checking fast moves - Screenshot mode: hides the controls and shows only the count bar, ready for screenshots or the iPhone's Screen Recording GREAT FOR - Dancers who find it hard to catch the counts in choreography - Posting count-synced dance videos to social media - Practicing solo while following the counts No account needed. Everything runs on your iPhone.

Verdict
The clearest difference is in-app purchases: 8Synk at none against Inventory Note's 1. 8Synk also leads on ads (none vs shown) and update cadence (every 3 days vs weekly). Inventory Note's advantage is device support (3 vs 1) and iOS requirement (15.5 vs 18.6). On price there is nothing between them.
