# Track your weight, or anything else

Canonical: https://godspeedmissioncontrol.com/guide/trackers

Start a message to Godspeed with "track", typed or dictated, in English or German ([Chat with Godspeed](/guide/talk-to-it)). Only "track journal" is different: it goes to your [work journal](/guide/journal).

## Start a weight tracker

1. Send today's weight:

   ```text
   track weight 81.5 kg
   ```

   Godspeed asks before it makes anything:

   ```text
   Start a new tracker called Weight, one number in kg, once a day? I've kept the 81.5 for today.
   ```

2. Answer `yes`.

   ```text
   Tracked: Weight 81.5 kg. From now on just say "track weight" and the number.
   ```

## Track it each day

```text
track weight 81.2
```

```text
Tracked: 81.2 kg, down 0.3 since Monday.
```

For another day, add it: `track weight 81.6 yesterday` or `on Friday`. A second weight on the same day replaces the first.

## Correct an entry

- `that was 81.4, not 81.2` changes the latest entry: "Changed: Weight on 14 October is now 81.4 kg."
- `delete the last weight` removes it: "Removed: Weight 81.4 kg of 14 October."

## See every day in a table

1. In the notebook's sidebar, open **Collections**. The **Trackers** shelf has a **Weight** card.

2. Open the card. Each row is one day, with your weight and a note. Change any row here, or add one with **New Item**.

A tracker you leave alone for 30 days moves into a fold called **Resting**, with every entry kept, until your next "track weight".

## Ask how it changed

```text
how has my weight changed this month?
```

The answer comes only from your entries. A coaching talk can look at them too: "The health talk may also look at my weight tracker" ([Start a coaching talk](/guide/coaching)).

## Track anything else

The same works for any number, such as `track belly 92 cm`. Other kinds:

- **Several columns:** "I want to track my sleep: hours, and quality from 1 to 5" sets up one tracker with both. Later: `track sleep, 7 hours, quality 4`.
- **No number:** `track sauna` offers a tracker that counts each time.
- **A name you choose:** answer its question with "call it Waist".
