Petwant (Petwant) Automatic Feeder - Reason for Discount

【Product Description】
This is a listing for a petwant automatic pet feeder.
The condition is very good. I am selling it because I no longer need it, but there is one issue that is causing me trouble. The app for this product is currently unavailable. I somehow lost the app on my smartphone when I changed devices. When I tried to reinstall it, I found it was no longer available on Google Play or the Apple Store. It feels like someone I lent money to has skipped town.
The app is still installed on my wife's iPhone and works perfectly.
Both the product itself and the app are highly polished and very well-made. It seems like a terrible waste. I would like to sell this to someone who already has the app (as shown in the 13th photo) or a professional who can create the app themselves.

【Product Condition Description】
The item is clean and has no malfunctions. However, since it cannot be used in its current state, I have marked it as Overall condition is poor. I will treat this as a junk item, so please understand that it is sold as-is with no returns or complaints (NCNR). Thank you for your understanding (_ _)
