Dark Surf gives Safari a thoughtful dark mode for every website. Instead of painting over pages, Dark Surf reads each site’s own design and rebuilds it in the dark. Backgrounds and cards turn deep and calm, text stays crisp, and the colors that carry meaning, like buttons, links, warnings and highlights, keep their character. Photos stay natural. SMART BY DEFAULT • Leaves websites that already have a dark design alone • Keeps dark logos, icons and formulas visible • Keeps text on top of photos readable • Handles modern websites built with CSS variables, Tailwind, Bootstrap and web components MAKE IT YOURS • Six themes: Midnight, Ocean, Dim, Warm, Graphite and true-black AMOLED • Build your own palette from any colors • Fine-tune brightness and contrast, and choose how images look • See every change instantly in a live preview that runs Safari’s own Dark Surf engine YOUR RULES • Switch any website between Dark, Invert and Off right from Safari • Keep lists of websites that are always dark, inverted or never themed • Follow a schedule or your device’s Dark Mode, or pause for an hour PRIVATE BY DESIGN Pages are recolored on your device. Dark Surf has no account, no analytics, no ads and no tracking, and never sends the pages you visit to anyone. Dark Surf is a Safari extension. After installing, turn it on in Settings › Apps › Safari › Extensions. The app shows you how.

Verdict
The clearest difference is in-app purchases: Dark Surf at none against Speedometer GPX's 1. Dark Surf also leads on ads (none vs shown). Speedometer GPX's advantage is update cadence (every 4 days vs every 4 months) and iOS requirement (12.0 vs 17.0). On price and device support there is nothing between them.
