Leave your mark. Keep your images looking their best. Invisible Watermark brings photo and video watermarking, invisible digital watermarks, a watermark camera, AI removal, and watermark extraction together in one app. Add a visible signature before sharing, or embed hidden information within an image. INVISIBLE DIGITAL WATERMARKS Embed your own information in an image without noticeably changing its appearance. Use watermark extraction to read embedded digital watermark information and help identify the source of your work. PHOTO & VIDEO WATERMARKS Add visible watermarks to photos and videos to give your content a recognizable mark. Useful for photography, product images, and everyday sharing. WATERMARK CAMERA Automatically add a watermark as you take a photo, saving you an extra editing step. AI REMOVAL Brush over the area you want to remove. AI removes the selected content and fills in the area for a cleaner image. ADVANCED WATERMARKS & EXTRACTION Work with text, black-and-white logos, and signature outlines. To extract an advanced watermark, select both the original image and the watermarked version for comparison. WATERMARK MANAGEMENT Keep frequently used stamps and templates in one place, ready to use again. From adding your signature to embedding hidden information and cleaning up an image, Invisible Watermark makes everyday watermark tasks easier.

Verdict
The clearest difference is price: 七海贴图 at Free against Watermark Toolbox's $2.99. 七海贴图 also leads on ads (none vs shown) and update cadence (every 2 days vs every 4 months). Watermark Toolbox's advantage is in-app purchases (none vs 3) and iOS requirement (13.0 vs 16.0). On device support there is nothing between them.
