Hi, I recently updated my app, Knowtrail, to have a stand-alone watchOS app which has already got very enthusiastic feedback in Reddit!
KnowTrail is an amazing application that lets you explore your surroundings by fetching information about places, events and other items of interest that are located near you!
KnowTrail even sports an Offline Mode allowing you to use it when no Internet connection is available. This way, you can use the app in its full extent without paying additional roaming fees!
And make sure to use Reading List whenever you want to save reading for later!
KnowTrail also allows you to access Wikipedia articles in the following languages:
Nederlands, English, Français, Deutsch, Italiano, 日本語, Português, Русский, Svenska, Español, 中文, العربية, Türkçe, Bahasa Indonesia, Polski, فارسی, Simple English, Tiếng Việt, 한국어, Română, Norsk (Bokmål), Čeština, Українська, Magyar, Suomi, עברית, Dansk, ไทย, हिन्दी", Català, Ελληνικά
You can download it here: Knowtrail for iOS and watchOS
