About this app
Metrava is an offline-first pocket workshop for Android. Measure, check, and work on site — no account, no cloud login, nothing uploaded to a Metrava server.
TOOLS
• Bubble level with two-position calibration
• Screen ruler (calibrate to a known length)
• Precision compass (true / magnetic north; check outdoors)
• Sound meter (dBFS until you set an SPL offset from a second meter)
• Frequency lab (tone generator and detector)
• Digital magnifier
• Piece counter
• AR measure (estimate; needs Play Services for AR)
• Network tools for the Wi-Fi you are on (confirm before a subnet scan)
• Bluetooth PC remote (some phones block HID)
HONEST ACCURACY
A phone is not a certified class 1 instrument. Uncalibrated sound is dBFS, not room SPL. The ruler depends on this display. AR is an estimate, not a steel tape. Network scan is not a full device inventory.
