Hello, I carefully reviewed your description and it is clear that you want a practical, no clutter replacement for the paper logbook that fits naturally into your daily slab billing flow. The focus on fast calculations, lot wise tracking, offline usage, and clean PDF invoices that can be shared instantly shows a very clear real world use case, and I am genuinely interested in understanding how you currently manage lots and billing on a busy day. The workflow you described around slab size entry, allowance based square footage calculation, lot level totals, and quick invoice generation is very clear. I am confident in delivering an Android app that keeps everything simple on screen, works fully offline, and produces reliable calculations every time without extra steps. Slab size entry with allowance logic, lot based sqft totals, offline data storage, PDF invoice generation and WhatsApp sharing. I have 7+ years of experience in mobile app development with strong focus on calculation heavy business tools, offline first architecture, clean user interfaces, and stable PDF generation. I would enjoy collaborating closely to ensure the app feels natural for your daily operations and reduces manual effort from day one. Let us schedule a quick chat to align your vision and next steps.

@amaank66

I’ll build you a clean, ultra-reliable Android app that replaces your paper logbook with a fast, field-ready workflow. Each slab entry will capture length, width, pieces, and instantly auto-calculate net sqft after applying your chosen allowance (3/6/9/12"). Every record is tied to a lot number with a live running total, ensuring zero manual math and zero errors. Billing becomes one tap: select lot → add/deduct charges → generate a crisp, professional PDF invoice saved locally and auto-opened in WhatsApp for instant sending. All features run fully offline using local persistence (SQLite/Hive), with smooth PDF rendering and a minimalist UI built in Flutter for long-term scalability. You’ll receive a signed APK, full commented source code, and 15 days of post-delivery fixes. Delivery in 20–25 days is fully achievable. Let’s begin. Best regards, Amaan Khan L. (CUBEMOONS PVT.)

@thedatafactory

I can build a simple, offline-first Android app to replace your paper logbook—allowing slab size entry, automatic allowance-based sqft calculation, lot-wise totals, and quick PDF invoice generation with WhatsApp sharing. The app will use a clean UI, reliable offline calculations, and smooth PDF output, built in Flutter or native Android. Delivery of a signed APK within 20–25 days, full source code, and 15 days of post-delivery bug fixes are included. Before starting, I had a few quick questions: Do you already have a sample or preferred PDF invoice format, or should I design a clean standard layout? What details should appear on the invoice (yard name, address, GST, phone, logo, etc.)? Will pricing be per sqft, or entered manually at billing time? Any future plans like data backup or multi-device use (can be planned later)? If this aligns with your expectations, I’m ready to proceed. Best, Param
