I first saw Retable on SaasHub when it wasn't on Appsumo LTD. I tried the Free trial version before and love it so far! I do not want to miss it when I realize that it's launching on AppSumo and I was surprised to see so many new features developed in such a short time. Actually, if you are tired of the complex interface and workspace-based fees of Airtable or traditional spreadsheets like Excel, you should definitely give Retable a chance. I also learned that the mobile app will be released in the coming months, it'll be game changer!
