Show HN: Lunch Money, a personal budgeting tool with multi-currency support

Hi Show HN, I'm really excited to share what I have been working on the side since late November last year.

I am a one-person team and this project has allowed me to harness and grow from my few years of experience working as a software engineer. I was also able to flex my design muscles a little bit, while learning some marketing along the way.

Stack:

* Node.js w/ Typescript backend

* React + Semantic UI w/ Typescript frontend

* Bull for Redis queues

* Postgresql for database

* (soon) Flutter for mobile app

Lunch Money is a personal budgeting tool with native multi-currency support. This 100% grew out of a need to expand and improve the spreadsheet we had been using for about 1.5 years prior to starting development on this. My main goal was multi-currency support but also to rethink certain aspects of budgeting. Check out the website for more details & screenshots!

If this looks interesting, I encourage you to try it out, especially if the multi-currency aspect is useful to you. Thank you and open to any feedback.

Side story: I started this project while living abroad in Fukuoka, Japan for a few months. I did a whole write up on that journey here: https://lunchbag.ca/lunch-money

Nice work! Looks great and easy to use. What do you use to get transaction history?

Thank you so much!

Kudos. You've gone and done something a lot of us only plan to do but never get around to.

I have a few questions though.

1. Does this work for everyone around the world?

2. How many ways do you have for sorting through transactions and making sense out of these?

3. My bank statements are a huge mess and I'd love a way I could aggregate all of my spend across multiple banks and cards. Sometimes, I send money to a friend only to get it back after a few days (or months, even). Would be great if you could link 2 transactions together like this as well.

This looks fantastic! I've used Mint to track my expenses and this looks way better (especially the course correction concept.) The biggest issue that comes up when entering financial data into something like this is how is the data stored and what security measures are in place? If my financial data was leaked, I know that hackers could use that to get access to my bank accounts.

Please don't take this personally, but reading through your blog post, you mentioned that you had limited DevOps experience that makes me a bit scared that regular security updates and security practices may not be something that you were thinking about when the app was being developed.

I'm going to signup and play with it regardless, but it would be really difficult to put my actual financial data in the app.

Question: Is security of user data something you have thought of? Do you plan to hire someone that is security minded if the app does well?
