Will need a business model revamp – UDictionary Translator Review

I found this app after another one (有道) temporarily disappeared from the app store - it came back after I downloaded U-Dictionary and subscribed for one year. My main use for this app is to translate camera/pictures from Chinese to English, which is a paid feature. This app is decent for that use in my opinion. iOS 15 now has that natively, built into the camera and Photos app, rendering this kind of app redundant to me. Honestly, I'd be willing to keep the subscription if it was something much, much cheaper - I'm talking USD 2-5 per year. At the current rate (USD 12.99 per month, or even "The Best Offer Ever" of 0.99/month for 6 months, then back to 12.99/month), this subscription (or any other in the same line) is a final "no, thank you" for me.
