‘Ive been using Calcapp for a few weeks and it is amazing. I was looking for a way to add a front end to complicated excel calculators. While you can’t import them directly, you can recreate them in an hour. It’s a really brilliant system.
@stuntlisting Thanks, that's great to hear!
Hey guys, it's great to finally be live on Product Hunt! We got our start years ago when my father asked me to create an app for the hospital department where he was working as a doctor. We sold that app and created another one for calculating drog dosages, which we also sold. During that process, I created an app maker enabling these kinds of apps to be created as easily as an Excel spreadsheet. Calcapp is now in late beta and we're adding useful features every day. The feedback we have received to date has been instrumental in shaping the product. We added the ability to send PDF and CSV reports from apps as a direct result of this feedback. I'm looking forward to hearing about your experiences with Calcapp! Please use this space to ask any questions you may have.
Great work. Is it possible to import excel files?
@bitrewards Hi Alexander. Not directly, but most spreadsheet formulas work as-is in Calcapp, meaning that you can transfer them simply by copying and pasting them. Here's a tip from our blog which explains a good workflow for converting spreadsheets:
Great job!! 😊 Will check it out!!
