How Thermometer compares

Each comparison says what the other app is genuinely better at. Thermometer does one thing — the outdoor air temperature on a real instrument — and these pages are about whether that is the thing you want.

• vs Weather Underground A station network against one instrument. Genuinely different propositions.
• vs Apple Weather Same data, different instrument. Including who should just keep Apple Weather.
• vs CARROT Weather Maximal and configurable against narrow and quiet. A taste decision.
• vs Mercury Weather Two design-led apps, different subjects. Scope is the difference, not craft.
• Comparisons Honest comparisons between Thermometer and the other weather apps on iPhone, including who should keep using what they already have.
