Just launched my first Android app! Looking for honest feedback on UI/UX.

Hi everyone,
I’m a solo developer and I just created "Fast Share Shopping List". I was frustrated with modern apps forcing registration and being cluttered with video ads, so I built a super clean, privacy-focused alternative.

Key features:

• Instant list sharing via QR code (using secure UUID logic)

• One-handed UI (Checkboxes are placed on the RIGHT side!)

• No login required / No forced video ads

I would love to hear your honest feedback or advice on how to improve this app. Check it out here:

Thank you, and happy hacking!
