I decided to pull the trigger with Feedbspace after carefully testing their free plan.
I strongly encourage people to do so, as it's better than buy and refund later.
The app is clean and fast, the UI polished and the UI super simple and fool-proof.
I've reached to the founder via the in-app chat and reported a few feedbacks and they were noted and the week after already implemented.
This means he's really caring for the app and willing to make it work.
The import function is good and so the form, and they're improving on a weekly basis.
I'd say that if they can scale and keep it profitable, this could be a real gem!
