Mini browser for the Watch. Features of the Watch app: - Visit your favorite websites on the watch - Keyword search via popular search engines - Quick search from complications - Search or browsing history - Favorite websites - Offline website snapshots (requires the iPhone app) Features of the iPhone app: - Create website snapshot then sync to the watch for offline browsing or add as favorite P.S. Spider mini doesn't need the iPhone app to run, it works independently on the watch with WiFi or Cellular connection. However we've built an iPhone helper app (the companion app of the watch app) which you may find useful.

Verdict
The clearest difference is price: iHorology at Free against Spider mini's $1.99. iHorology also leads on iOS requirement (12.0 vs 17.0). Spider mini's advantage is update cadence (every 9 days vs every 2 months). On ads, in-app purchases and device support there is nothing between them.
