Data

The Data tab is the hub for everything analytical about the selected vehicle. It shows the Latest Reading card (for connected EV vehicles) at the top, followed by a list of pushable destinations: Stats, Charts, Map, Efficiency, and Readings.

Every detail screen below shows the vehicle’s name as a subtitle under its title so you always know which car you’re looking at.

Latest Reading Card

When the selected vehicle has a connected service integration that returns energy data (Volvo, Toyota EVs), a snapshot card sits between the vehicle picker and the menu list. It shows up to three at-a-glance metrics:

• Odometer (km / mi) — current mileage from the latest snapshot.
• Battery (%) plus an estimated remaining range if the API returns one.
• Fuel (L / gal) plus an estimated remaining range — for plug-in hybrids whose API exposes fuel level.

A timestamp on the right tells you how long ago the snapshot was taken.

Gestures

• Tap the card → opens the snapshot detail (every field returned for that snapshot).
• Long-press the card → triggers a manual fetch from the vehicle API. While the fetch is in flight, an inline spinner replaces the timestamp.

A welcome hint on first use explains both gestures. It dismisses itself the first time you use either.

For non-EV or non-connected vehicles, this card is hidden and the menu list starts right after the vehicle picker.

Stats

Tap Stats for a comparison of three time periods:

• Last Month — fill-ups in the last 30 days.
• Last Year — fill-ups in the last 365 days.
• All Time — every fill-up on file.

Each period shows:

• Total Spent — total amount spent on fuel.
• Total Fuel — total volume added.
• Fill-Ups — number of fill-up records.
• Avg Efficiency — average fuel efficiency, when computable.

If you have a default currency set, amounts are shown in that currency. Fill-ups recorded in other currencies are converted using the exchange rate at the time of the fill-up.

Charts

Tap Charts for a visual trend chart. You can switch between:

• Mileage — cumulative odometer over time.
• Efficiency — fuel efficiency trend.
• Fuel Price — price per unit trend.
• Cost/km — running cost per kilometre.

Use the period selector below the chart to filter by time range — All, YTD, Prev Y, This M, Prev M, or Custom. A summary section underneath shows total spent, total fuel, fill-up count, and average efficiency for the selected period.

Map

Tap Map for a full-screen map showing every location-tagged record for the selected vehicle — fill-ups, costs, and charging sessions on a single map. The map auto-centres and zooms to fit every pin. If the selected vehicle has nothing geo-tagged, an empty-state message explains how to enable it (see Fuel Tracking → Location Capture).

Pin Types

A pin’s coordinate comes from the entity’s stored GPS — entries without a location are silently excluded from the map.

Clusters

When two or more pins (of any mix of types) overlap at the current zoom level, they collapse into a single round badge showing the count. Tap a cluster to zoom in; the pins will split into smaller clusters or individual pins as the camera moves. If pins share the exact same coordinate (e.g. several fill-ups at the same gas station), tapping the cluster instead opens a chooser list with mixed-type rows.

Filtering

A ≡ filter button sits in the toolbar (top-right). Tap it to reveal three toggles — Fill-ups, Costs, Charging sessions. Turn any off to hide that pin type from the map. The filter resets to “all visible” each time you re-open the Map (it isn’t persisted).

When all three filters are off, an inline empty state says “Nothing to show — turn a filter back on.”

Tapping a Single Pin

Tapping a pin slides up a per-type detail sheet:

• Fill-up → date, fuel type, odometer, volume, price/L, total cost, plus a View Details button that pushes the full editable Fill-Up detail.
• Cost → date, category icon, amount, plus View Details to push the Cost detail.
• Charging session → date, location name (if set), kWh, total cost, plus View Details to push the Session detail.

Efficiency

Tap Efficiency for a period-aware breakdown of fuel and EV consumption alongside one another. A Granularity toggle switches the chart between:

• Per fill-up / per bill (default) — one chart point per record.
• Daily — one point per day, derived from the snapshot stream (requires a connected service). For EVs without Battery Capacity (kWh) set, the Y-axis is km / %; with capacity set, the chart switches to kWh / 100 km.

A summary card at the top of the screen shows period totals and average consumption. The period picker matches the one on Charts.

Readings

Tap Readings for a flat chronological list of every energy snapshot fetched from your connected services. Each row shows the timestamp, odometer, battery (and fuel where applicable), and a trigger badge:

• Scheduled (grey) — a routine background or Shortcuts fetch that succeeded.
• Manual (accent) — a user-triggered fetch (from the Latest Reading card long-press or the toolbar button on this screen).
• Failed (red) — a fetch attempt that didn’t produce a snapshot. The row’s subtitle shows the reason.

A toolbar button at the top-right of the list triggers a manual fetch on demand. Useful for testing that the integration is alive or for prompting an immediate snapshot before recording a fill-up.

Switching Vehicles

Use the vehicle picker at the top of the Data tab to view data for a specific vehicle. Each vehicle has its own independent Latest Reading card, stats, charts, map, efficiency, and readings list.
