About

Indoor temps, from the people already there

Thermly is a free map of how warm businesses actually feel inside. Cafes, restaurants, gyms, shops, libraries — if you’ve sat there long enough to notice the air, you can log it. Everyone else can search by place or by a temperature range that feels good to them.

How it works

  1. Open the map. It centers on you so nearby places show up first.
  2. Search a business. If it isn’t there, add the pin yourself.
  3. Log the indoor temperature — wall thermostat, handheld thermometer, or how it felt. Optional: photograph the display so others can check it. The displayed temp is a weighted average (instrument and photo count more).
  4. Filter for warmer than, cooler than, or a comfort band you set.

Why it exists

Outdoor weather is everywhere. Indoor weather is a surprise until you’re already in the door. Thermly is the missing layer: a community logbook, not a thermostat company. It only stays honest if people keep reporting.

Free to use

Browse without an account. Signing in lets you log readings, keep a rank (Temp Starter through Temp Guru), add friends, and share an invite code. Optional alerts ping you when a friend logs a temp.
