What this app is. What it isn’t. What you could build.

One-liner

Strengths

Accurate tax rate calculations across all Canadian provinces and major cities (review: 'Works perfectly for Ontario and BC')
Clean, minimal interface with fast lookup of tax rates by city or postal code
Offline functionality—no internet needed once installed
Regular updates to reflect changing provincial tax laws
Highly rated for reliability and trustworthiness (4.78 avg from 6k+ reviews)

Weaknesses

No support for multi-item transactions or bulk tax calculation (review: 'Would be better if I could add multiple items at once')
Limited customization—can't save frequently used locations or settings
No export or receipt logging feature (review: 'I wish I could save my calculations')
UI feels dated; lacks modern design polish compared to other finance apps
No integration with accounting tools like QuickBooks or Xero

Opportunities

Build a multi-item tax calculator with subtotal + tax breakdown
Add location history and favorites for frequent users (e.g., Toronto, Vancouver)
Integrate receipt scanning or manual entry for tax tracking over time
Offer a Pro version with export to CSV/PDF and sync across devices
