- A new typewriter-style PDF template (Settings → PDF format): typewriter type for text and numbers, and dashed rules that look like typed lines.
- The typeface is downloaded the first time you use the template. Without an internet connection, the PDF is created with the standard typeface.
Improvements
- In light mode, cards now stand out clearly from the background.… more - 🆕EasySeikyu: Invoice & Quote first spotted by AppInsider#94 in Top Grossing · Business · Japan (found via developer)
- 📦EasySeikyu: Invoice & Quote version 1.16.5Bug Fixes
- Closing the line item editor without saving could change the line amount while leaving the subtotal and total out of date. Fixed.
- Line items, subtotal, tax and total now always match: documents are recalculated with your current rounding setting when opened, when a PDF is created, and in lists and reports.
- When several documents are combined into one invoice, their discounts are carried over per tax rate, so the total matches the original documents.
- Going back from the item, business information or bank account editor without saving no longer keeps the unsaved changes.
Improvements
- Document Settings are now saved as soon as you change them; there is no Save button any more.… more - 🆕EasySeikyu: Invoice & Quote released on the App Store

Review momentum
20/100
faster than 0% of Business apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
