Know your elevation. Follow pressure changes. Keep a useful record of your hikes, climbs, stairs and everyday observations—with clear readings on iPhone and iPad, plus Apple Watch, widgets and Live Activities on supported devices. • Current altitude above sea level, with relative gain and net change kept separate. Check the reading source and freshness; authorized GPS can provide a fallback where available. • Start, pause, resume and save a recording. Authorized background recording keeps a session going while you use another app or lock your phone. • Find, rename and favorite saved recordings, add notes, compare charts and share data as CSV. • Check your wrist, widgets or Live Activity. Use Siri and Shortcuts to read, record or open saved sessions; interactive controls are available on supported OS versions. • Keep familiar metric/imperial units, Set Zero and pressure-reference calibration. Choose automatic weather, manual reference or a nearby US weather station where available. Readings depend on device hardware, permissions, source availability and conditions. Widgets and complications refresh on the system's schedule, not continuously. Watch recording controls need a reachable iPhone; phone-free Watch recording is not included. Saved history and supported local readings work offline; weather and station updates need a connection. HowHigh is for observation, not certified navigation or safety-critical guidance.

Wikilinker automatically adds Wikipedia links to the people, places, organizations, and other notable names mentioned in any webpage. Each name is linked only on its first occurrence, keeping the reading experience clean. How it works: Wikilinker scans article text for proper nouns and acronyms, matches them against a bundled bloom filter of the top 1,000,000 Wikipedia titles (ranked by pageviews), and adds unobtrusive links directly in the page. Everything happens locally on your device — no API calls, no external requests, no logging. Features: - 1,000,000 names in a bloom filter bundled locally (under 2MB) — no network requests - First-occurrence-only linking keeps articles readable - Smart filtering avoids false positives on common words - One-click enable/disable from the toolbar - Works on any website, optimised for 19 major news sites Completely self-contained. No data collection, no analytics, no tracking, no accounts. The only stored value is your enabled/disabled preference. An updated version of the Wikiproxy, originally built in 2004.
