Would you use an app that helps cut your energy bills without installing any hardware?

Hi everyone!

I’m currently working on a new energy-saving app and would love to hear your opinions.

I’m exploring an idea for a simple app that helps people reduce their energy bills for households and small businesses. Without needing to install any hardware.

If this app helped you save around £20–50/month on your energy bill, would you consider paying a small monthly fee for it (e.g., £3–£7-£15)? Why or why not?

It could suggest things like time-of-use optimizations, identify overconsumption patterns, and even detect silent energy drains.
I’ve created a short questionnaire to understand what people are struggling with and what they’d actually use.

Would love your thoughts, feedback, or especially criticisms. Thanks in advance!
