WhatsApp Activity Heatmap

Load a WhatsApp export locally and see which days carried the conversation.

On iPhone: open the chat → tap the contact name → Export Chat → Save to Files → return to your browser and load the file locally.

On Android: open the chat → ⋮ menu → More → Export Chat → Share → pick your browser.

If another parser tool already loaded this chat, the heatmap reuses that local result.

How it works

  1. 1Export a WhatsApp chat as .txt or .zip.
  2. 2Load it here or reuse a locally parsed chat from another tool.
  3. 3Pick a year and export the heatmap image.
