Aidem makes it easy to organize, annotate, clip, and share videos (audio is also supported). It helps you add memos while watching video courses. This way you can quickly find the clips you want based on the memo next time. Each memo offers independent playback controls, so you can easily play video clips without dragging and easily share clips when needed. What's more, Aidem provides several convenient gestures to help you control video playing better: • Tap with two fingers to play video or pause playback. • Move horizontally with two fingers to seek precisely, or play video backward/forward fast. • Long-press the right side of the player with one finger to temporarily increase playback speed; while holding, slide up or down to fine-tune the speed. • Pinch to zoom when displaying media in full screen. ◆ ◆ Main Features ◆ ◆ • Support adding memos to video; • Independent memos outline view; • Include Tags & Bookmarks; • Convenient file transfer among devices; • Auto-lock (Premium); • Read-only mode (Premium); • Watermark video to share if needed (Premium); • Sync data among devices via iCloud (Premium). ◆ ◆ Release Notes ◆ ◆ https://aidem.kjuly.com/#/release_notes ◆ ◆ Terms of Use ◆ ◆ https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ ◆ ◆ Customer Support ◆ ◆ If you have any questions or suggestions, don't hesitate to contact me via mail: support@kjuly.com .
