Goal
Create a fast, ad-free, and private tax calculation utility
The challenge.
Most utility apps on the market are cluttered with intrusive ads, have confusing interfaces, and often raise concerns about data privacy. The challenge was to design and develop a tax calculator specifically for Quebec that defies this norm. Our goal was to create the absolute simplest, fastest, and most trustworthy tool for daily calculations, prioritizing user experience and privacy above all else.
User-first: speed, accuracy, zero distraction.
We adopted a user-first philosophy focused on speed, accuracy, and a distraction-free environment. The business model itself became a key feature, reinforcing the app's premium quality and respect for the user.
- Ad-Free, One-Time Purchase We eliminated all ads and subscriptions in favor of a single, affordable one-time purchase for lifetime access, guaranteeing a clean user experience.
- All-in-One Functionality The interface was designed to seamlessly combine tax calculation, tip calculation, and bill splitting into a single, intuitive workflow without unnecessary screens.
- Privacy by Design We engineered the app to perform all calculations locally on the device, ensuring no personal or financial data is ever collected or transmitted.
Key features.
The result.
The Québec TPS TVQ Calculator has become a go-to utility for residents by delivering on its core promise: to be the simplest, most respectful, and ad-free calculator on the App Store. Its success proves that a user-centric design philosophy, combined with a fair pricing model, can create a highly-rated and trusted mobile application that users are happy to pay for.
