SweepTrack

SweepTrack — from idea to a shipped field product

You're in a field, one hand on the detector, gloves on, maybe after dark. Every screen had to work under those conditions.

The SweepTrack mark: a continuous green line tracing the shaft and search coil of a metal detector into the shape of an S.

One line traces the shaft and coil of a detector and resolves into an S. It had to survive being an app icon first — so it was drawn at 48px and grown from there.

SweepTrack map screen: a satellite view of farmland with the user's green heading marker on a track, layer and centre controls at the right, and the record control in the centre of the bottom navigation bar.

Map — live session, satellite base layer

Context

SweepTrack is an Android app for metal detecting. It records where you walked, pins your finds to the track, and keeps sessions, maps and stats in one place.

It's my own product — concept, name, mark, interface, and design direction through to the Play Store.

The design decisions come from the field. Screens get read at arm's length in daylight and after dark, so the interface is dark-first, the main controls sit under the thumb, and there's a red night-vision mode for when your eyes have adjusted to the dark and you'd like to keep it that way.

SweepTrack-RO came after — the same identity and system, adapted for the Romanian market.

Interface

Built to be read outdoors, at arm's length.

  • SweepTrack history screen: a summary bar showing sessions, distance, finds and duration, a row of recent find photographs, and dated session cards each listing distance, duration, finds and average speed.

    History — sessions, finds and totals

  • SweepTrack detector presets screen listing saved detector configurations with search mode, frequency and sensitivity for each, and the active preset outlined in green.

    Detector presets — saved machine configurations

  • SweepTrack tools screen rendered in night-vision mode: the whole interface in red on black, with grouped field tools, research and analysis entries.

    Night vision — red on black, to protect dark adaptation

System

Three decisions the rest of the product hangs on.

Typeface

Inter for interface, Space Grotesk for display, JetBrains Mono for numerics

Numbers get read at a glance mid-session, so they get a monospaced face and their own hierarchy.

Colour

#00FF6A on near-black, plus nine selectable palettes

One green carries the brand. The other palettes are the user's to pick.

Structure

Persistent bottom navigation with the record control at centre

A session can be started and stopped one-handed without looking away from the ground.

Identity in application

The SweepTrack Google Play feature graphic: the wordmark and mark in green on a near-black field with a map track motif.
