Altitude - Elevation Altimeter

AltitudeKit puts a real-time GPS altimeter, a precision compass, and a watermark camera into a single light-weight app — built for hikers, climbers, road-trippers, and anyone who wants their photos to remember exactly where they were taken. Stamp every shot with altitude, coordinates, date, and place name using one of eight built-in templates. All eight are unlocked from day one, no paywall, no "premium pack". LIVE ALTITUDE — METRES OR FEET • GPS + barometer fusion for accurate elevation, with a green/amber/red trust bar so you always know how confident the reading is • Real-time pressure trend (rising · falling · stable) • Manual calibration against a posted sign — your offset persists for the rest of the trip A REAL OUTDOOR COMPASS • Choose true north or magnetic north • Decimal degrees, DMS, UTM, or MGRS — long-press to copy • Reverse-geocoded place name plus speed and heading of motion WATERMARK EVERY PHOTO • 8 free templates: Xiaohongshu Lite, Minimal Mono, Film 35, Journal, Handwritten, Marine, Mountaineer, Digital Compact • Toggle altitude, coordinates, date, weather, temperature per shot • Add a custom subtitle ("With Mom — Yosemite trip") • Saves to your Photos library; original frames untouched • Re-stamp existing photos: import any picture with GPS EXIF and apply a watermark A TRIP JOURNAL THAT BUILDS ITSELF • Photos auto-group into Sessions by time and location • Track recorder logs altitude curves on demand • Achievements unlock as you climb past sea level → 3,000 m → 5,000 m → 6,000 m → Everest → cruising altitude • Year-end recap collage on January 1st BUILT FOR EVERYWHERE • Home Screen and Lock Screen widgets (Small / Medium / Large + Circular / Rectangular) • Live Activity in the Dynamic Island while a track is recording • iPad sidebar with a 4-column album • Optional iCloud sync across all your devices • Forced light mode — no dark-mode surprises out in the sun REMOVE ADS (one-time) Altitudekit is free with two small ad placements: a banner under the dashboard and album, and an interstitial that occasionally plays after exporting a watermarked photo. A one-time $9.99 purchase removes both forever and supports a solo developer. Not a subscription, no recurring charges.
