One-liner
A simple calculator that helps users determine how many rolls of toilet paper they need based on household size, usage frequency, and roll length.
Strengths
- Accurately calculates TP needs based on user-defined variables like number of people and daily usage
- Simple, no-frills interface with minimal distractions (repeated in multiple reviews)
- Highly rated for reliability and usefulness in everyday planning
- Uses a humorous tone without sacrificing functionality (e.g., 'shitty' keyword ranking suggests brand personality resonates)
- Lightweight app with fast performance and low resource use
Weaknesses
- No customization for different roll sizes or types (e.g., double-ply, ultra-thick) — users complain about this in reviews
- Lacks data persistence: settings reset after app restart (mentioned in review #42: 'I have to re-enter everything every time')
- No export or sharing feature for calculations (review #78: 'Would be great to save or share my results')
- No dark mode despite being a utility app (review #103: 'Why no dark mode? It's annoying at night')
- Limited language support — only English (review #115: 'Need Spanish version')
Opportunities
- Add roll type and size presets (e.g., Charmin, Costco, budget rolls) to improve accuracy
- Introduce cloud sync or local storage to preserve user preferences across sessions
- Build a family-sharing feature where multiple users can input their own usage habits
- Add a 'panic buy' mode that factors in supply chain delays and stockpile thresholds
- Localize the app into Spanish and other major languages to capture non-English users
