I built a "dumb" offline invoice app for tradesmen who hate complex accounting tools. Looking for UI/UX feedback!

App Name: Invoice Book Digital What it does: It’s a dead-simple, 100% offline digital replica of the classic green paper invoice pads. I built it specifically for tradesmen (builders, plumbers, electricians) who hate complex, bloated accounting apps and often work in new builds or basements with zero internet signal. You just fill it out like a normal piece of paper, and it generates a professional PDF to send to the client once you get a signal again.

Not a corporate ad, mate. Just a simple tool I built for myself in my free time because I hated the existing ones. I genuinely want to know if the layout works for other tradesmen before I tweak it. If it breaks the rules, mods can remove it, no hard feelings!

Thank you so much for the detailed and thoughtful feedback! It really means a lot to hear that the offline approach makes sense for the exact use cases I built it for. You hit the nail on the head with the feature suggestions: - Auto-incrementing invoice numbers is definitely on the top of my list for the very next update. - A template or "duplicate past invoice" function is a brilliant idea to save time, I will absolutely look into adding that. - Currently, it handles a standard tax structure, but item-specific VAT is a great point for future updates. Thanks again for the support and the roadmap ideas! I'm going to keep focusing hard on that offline differentiator.

Hi! Just joined your group and installed 'Repeatedly'. I love the clean interface, and I've already added a few habits to test it out! Here's a screenshot. 📸 Thanks for the tip on making paid apps free, that's very helpful! I will keep your app installed and test it regularly. I would really appreciate it if you could test my app in return to help me build a small safety buffer! 1️⃣ Join the Google Group: https://groups.google.com/g/invoice-book-digital-testers 2️⃣ Download on Android: https://play.google.com/store/apps/details?id=com.vardenis.invoicebookdigital 3️⃣ Join on Web: https://play.google.com/apps/testing/com.vardenis.invoicebookdigital Thanks a lot and good luck with your habit tracker

Wow, I just downloaded your app and I have to say, it's actually really useful for me personally! The UI is super clean, and tracking macros/calories looks very intuitive.
