Reflex: Particles Effects is an iPhone application developed by Sviatoslav Belmeha. It falls under the category of multimedia and offers users the ability to create stunning videos with unique effects based on movement detection.

With Reflex, users can record live videos and apply effects in real time, as well as apply effects to pre-recorded videos from their camera roll. The app also allows users to take photos and apply different effects simultaneously on the same video. One of the standout features of Reflex is its ability to detect people in frames and apply effects only to them, adding an extra level of customization to the videos.

For inspiration and to see the effects in action, users can visit the Reflex Instagram page and Twitter page

Reflex also offers a Pro subscription mode, which provides full access to all effects and settings, recording in FullHD, and the ability to remove watermarks. The prices for the Pro mode subscription may vary by location.

Please note that some icons in the app are created by Icons8, and videos for effect previews and screenshots are sourced from Pexels. The sound used in the video preview is from Usemysound.
