Fieldeng

The phone is the instrument.

Measure. Calculate. Diagnose. Record.

Fieldeng is an offline toolbox for engineers and technicians. Capture a reading at a site, run the calculation, read the formula, keep the record. No account. No cloud for core use.

Get on Android

$9.99 one-time when the Play listing ships. Camera and ML plates come next; these shots are the live app.

Capture at the site, then file it.

Type it, speak it, or photograph a display. You confirm every camera reading before it fills a field. Home keeps the last work. Sites hold the place — each with its own mark.

Fieldeng Home: map of sites, recent cellular readings on this device. Fieldeng Home in dark theme: nearby sites and cellular sparkline.

The phone is a toolbox of instruments.

Lay it on the work. Point it at a heading. Listen to the radios. Camera display and gauge plates come next — you still confirm before a reading is saved.

Level vial at 0.23°, bullseye, ready to capture. Level vial in dark theme at 3.36°.
Level Gravity. Six modes. Hold to capture.
Compass at 164° south, true north, elevation 19.3°.
Compass Heading, true north, elevation.
Wi-Fi connected reading, −53 dBm. Wi-Fi environment scan, −52 dBm.
Radios Wi-Fi, BLE, cell, LAN. On this device.

Also on Field: Point, Camera, Number, Note, Voice. Same tab. Same confirm.

Every tool has the formula on the face.

Calculators are part of the kit, not a mystery box. Simple is the working face. Reference shows the expression, the assumptions, and where it came from. Learn the job while you run the number. ML never computes the engineering result.

life = (m × C × u × 3600) / I

Anode Life, from the Reference tab. Same pattern on the rest of the catalog.

Anode Life Reference tab with formula, assumptions, and provenance. Anode Life Reference tab in dark theme, same formula and assumptions.

The loop the app is built around.

Measure, calculate, diagnose, document. Then measure again.

Fieldeng in the center of a loop: measure, calculate, diagnose, document. Fieldeng in the center of a loop: measure, calculate, diagnose, document.

Measure

Field capture: number, note, voice, or camera. Phone instruments for level and bearing. Confirm before it is saved.

Calculate

Domain tools from electrical and CP through HVAC, fluids, and survey. Simple on the surface, Advanced when the job needs it.

Diagnose

Field context on the result. Observations, never a pass or fail, never a substitute for qualified judgment.

Record

Save to a site on this device. Compare later. Export when you choose. Core use works with no signal.

One kit, many jobs.

Each module is a color mark on Tools — icons only, never the titles. Open one to see the calculators. Every one has the formula on Reference.
