Very glad to hear it’s not a bug in our app 🙂
With the sharpness issue, would you mind please emailing us a before HEIC file and after JPG or PNG file to support [at] ribbet.com. You can make save appear by making any change (e.g. Autofix) and then undoing that change. We will then be able to compare to see if we can resolve this sharpness issue.
Is the issue apparent if you zoom right in on your photo (within the Ribbet app)? Perhaps it is just apparent when zoomed out.
Regards – The Ribbet Team
