Simplify Budget VS Diffyn

Simplify Budget's answer

The visual monthly grid interface. Instead of scrolling through transaction lists, you see your entire month as a calendar where days are rows and expense categories are columns. One tap where they intersect logs your expense. It's the first budget app that shows spending patterns at a glance, plus your data lives in YOUR Google Sheets forever - no vendor lock-in.

Simplify Budget's answer

Digital nomads, families, and professionals who want visual expense tracking without recurring fees. Typically tech-savvy individuals aged 25-45 who value data ownership and hate subscription models. Many are former YNAB/Mint users seeking alternatives after price increases or service shutdowns. They prioritize privacy, family collaboration, and long-term value over bells and whistles.

Simplify Budget's answer

After manually tracking finances across 25 countries as a digital nomad, I realized existing budget apps were either too expensive, too complex, or held your data hostage. I built the visual expense tracker I wished existed - something that shows spending patterns instantly and works anywhere. When Mint shut down and YNAB raised prices again, I knew others needed this too. One-time payment, your data stays yours.

Diffyn's answer:

I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
