### 4/5 — Good, but a couple of UI bugs

*2026-03-21*

Its simple and does the job, but could be improved. Also the lifetime price is too expensive for this kind of functionality - i would pay but its not worth $60

**Developer response:** Thanks for the feedback, I really appreciate it. Glad to hear it’s been useful overall.

I’d love to learn more about the UI bugs you ran into or any other improvements you’d like to see. You can reach me at support@poolistry.com or through the Contact page in the app.

I understand your point on pricing and appreciate you sharing that feedback.
