Pocket EDC

About

Pocket EDC puts twenty-one field tools on the device already in your pocket: instruments and quick-reference cards for navigation, leveling, lighting, optics, and the field. Ten are free, including a true-north compass (full World Magnetic Model, not an approximation), flashlight, stopwatch and interval timer, camera protractor, mirror, and reference cards for fire craft, first aid, Morse code, cloud types, and the NATO phonetic alphabet. A one-time $5.99 Pro unlock adds the other eleven: bubble, spirit, and plumb levels, a tilt and grade gauge, a barometric altimeter, a sun-aim signal mirror, a sundial, strobe / SOS, a magnifier, an illustrated knot guide, and the Beaufort wind scale. Organized into four tabs (Navigate / Level / Gear / Reference). Every tool works offline; the only network use is verifying your one-time purchase.

What it does

What you get free, and what the $5.99 unlock adds

Accuracy and limitations

Pocket EDC's compass, leveling, tilt, and altimeter tools read your device's built-in magnetometer, accelerometer, and barometer. These are consumer sensors that drift, respond to nearby metal and electronics, and need a brief figure-8 motion to recalibrate after a magnetic disturbance; the barometric altimeter estimates altitude from air pressure and should be calibrated against a known reference. Readings are useful for everyday work but should not be relied on for safety-critical, navigational, surveying, aviation, or professional measurement purposes. The Reference tools (Fire Craft, First Aid, Morse Code, Cloud Types, Phonetic Alphabet, Knot Guide, and the Beaufort scale) are quick-reference aids, not professional instruction; the First Aid card in particular is not a substitute for training or emergency medical care.

Permissions Pocket EDC requests

Camera

For the camera-based tools (Magnifier live zoom, Mirror front-facing view, the Protractor camera overlay, and the Signal Mirror viewfinder) and to control the camera LED for the Flashlight and Strobe / SOS tools. No video is ever recorded; frames are processed in memory and discarded, except when you explicitly tap Save in the Magnifier to write one frame to your gallery. Pocket EDC does not read your existing photos.

Precise location

For the Signal Mirror and Sundial tools, and the Compass "true north" toggle (off by default), which compute the sun's position and your magnetic declination from your latitude / longitude / time. Location is read on-device only, is never stored or transmitted, and is requested only when you first use one of these features.

Internet

Used only for the one-time purchase and restore flow (Google Play Billing and RevenueCat). Every tool works offline; no tool sends any sensor reading, image, or location off the device.
