Feedback and quick QA of a new app

This job will probably only take you about 1 hour. I have a new app, called "Invoicerator", and I want you to simply download it and offer your honest assessment of the app. In particular: * Did the app open for you, without crashing? * Are there any features that you would recommend adding to the app? * General impressions? Needs work? Already good? Could use more features? UI/UX is lacking? * Was the app user-friendly? In other words, just download the app, test it for a few minutes, and give me your assessment. Here are the links to download the app. iOS is preferred, but either would be fine. Apple App Store:  https://apps.apple.com/us/app/invoicerator/id6757256214 Google Play Store: https://play.google.com/store/apps/details?id=com.bixbyapps.invoicerator I will likely hire up to 20 - 30 upwork users for this project, so that I can get a diverse range of opinions.
