Keep your error rate on your Home Screen

Short answer: send your error rate to WidgetDash with one HTTP request, then add the WidgetDash widget to your iPhone Home Screen or Lock Screen. It updates every time you push a new value, and it is free for up to 5 numbers.

A rising error rate is the earliest warning that something is wrong, and you want it in your pocket, not buried in a dashboard. Pull the percentage and the raw error count from your logs or APM and push both. When the widget jumps, you know to look before customers complain.

Push it with one request

A source is created automatically the first time you push to it, so there is no setup step. Send your error rate like this:

curl -X PUT https://api.widgetdash.app/api/v1/data/error_rate \
  -H "Authorization: Bearer YOUR_WRITE_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "display_name": "Error Rate",
    "icon": "exclamationmark.triangle.fill",
    "category": "DevOps",
    "metrics": [
      { "label": "Last hour", "value": "0.12%" },
      { "label": "5xx", "value": "3" }
    ]
  }'

• The value is a plain string, so format it however reads best: "$8,420", "99.98%", "+58".
• icon is an SF Symbol name. Here we use exclamationmark.triangle.fill.
• Push to the same source_key again any time and the widget updates in place.

Add it to your iPhone

1. Sign up free and copy your WRITE key from the dashboard.
2. Install the WidgetDash iOS app (free on the App Store) and connect with the dashboard QR code or your READ key.
3. Long-press the Home Screen, tap +, search WidgetDash, pick a size, then choose this source.

Small Lock Screen widgets are supported too, so your error rate can sit right under the clock.
