I built my own financial planinng app
A few years ago, I started managing my finances using Google Sheets. It worked fine for a while, but then I hit some limitations. As my financial planning needs grew more complex, I found myself struggling with tracking assets and forecasting future financial scenarios. Thus, I started to work in my spare time on building FinancialAha: https://www.financialaha.com - a financial planning app designed to do everything my spreadsheets couldn’t. It is completely free and I intend to add some paid features later on as listed on the pricing page, but I want to keep it free for people…

I spent 2 years building a personal finance simulator2023 · projectionlab.com · ▲766Hey everyone! After another year of building as a solo dev on nights and weekends, I'm back with an update on this post: https://news.ycombinator.com/item?id=31083093. TL;DR - ProjectionLab (https://projectionlab.com) is a privacy-friendly personal finance planning tool where you can create financial plans that go beyond the standard online retirement calculators. And by popular request, it now supports self-hosting for Lifetime users! Something I'm grateful for is that our community here on HN is the difference between PL existing and not. There was actually a time…
Write It Down – Personal finance tracker2025 · write-it-down.com · ▲271Everyone’s chasing AI hype. I built a Google Sheet and it quietly took off. In 2020, I made it to track my own finances for income, expenses, savings, yearly summaries etc. I shared it once on Reddit, forgot about it for a year… When I checked back, it had over 130k views and I was honestly stoked! No launch. No funding. No AI. Just a spreadsheet people actually stick with and find useful. I finally gave it a proper home: write-it-down.com Now, more than 2,300 people use it. It’s intentionally boring and that’s why it works. People don’t always need AI. They just need something that actually…
FinancialAha! Ultimate SpreadsheetsMay 2026 · financialaha.com · ▲11I got frustrated with every financial calculator requiring an email before showing results. So I built alternatives. 28 calculators - retirement, FIRE, compound interest, rent vs buy, debt payoff, etc. Everything runs client-side. No data tracking - full privacy.
Guitos, a free open-source budgeting app2023 · guitos.app · ▲53Hi HN, I wanted to share an app I've created recently since it might be useful for you: guitos is a free open-source budgeting app that helps you figure out where your money went and plan your budget ahead of time. It was initially created to replace a spreadsheet I created based on the budgeting advice given on the r/personalfinance subreddits and as an opportunity to learn React. The app stores data in your browser's local storage (IndexedDB). Your private financial data doesn't leave your browser. (If you're wondering what the app's name means: "guitos" is portuguese slang for…
