### 1/5 — Great idea, doesn’t work

*2023-06-28*

App crashed during setup. When I reloaded it, it skipped the setup process. Now I’m being shown a bunch of stuff which is irrelevant, like rooftop solar, when I live in an apartment. Needs work.

### 5/5 — Simple and clear tracking

*2023-04-19, version 2.0*

This is exactly what I’ve been looking for. An easy and simple way to track all my various energy uses while also giving me clear ways to act on getting more efficient and reducing carbon.
