Confin

October 22, 2019

Confin

With this blog post I want to present my finance app for iOS and Android.
You might ask if another finance app ist really necessary so I try to quickly explain the benefits of Confin and differences to other common apps.
Confin is basically my first real (published) side project and went through multiple iterations and reworks.

Manual interaction

This point may seem unintuitive on first sight, let me quickly explain. Most/all other apps are directly linked to your bank account and automatically assign every booking a proper category.
I don’t like this for two reasons:

  1. Call me old-fashioned but I don’t like the idea of having a direct connection between my bank accounts and mobile phone
  2. I want to use a finance app to have a better feeling and understanding for my financial situation. However if everything happens automatically it’s more likely to lose control

Custom accounts

Custom accounts are accounts that don’t represent a direct bank account, for example cash or carsharing. I have to pay for carsharing once a month, but after each drive, I get a notification how much this just cost. But with a separate account those costs are always visible and represented in my overview. And when the payment is due, I can just do a transfer from my bank account to the carsharing account to balance everything out. Same principle goes for cash.

Statistics

Not much to say to this topic. There are different kind of statistics, for example monthly distribution or evolution over time.

Private budget

This one is one of my favorite features. It is a planning tool for periodic fix costs to help you better understand how much money is available monthly. You can enter your monthly/quarterly/… incomes/costs and it calculates your day to day budget. It even lets you know how much money you should save monthly for the costs that happen in bigger time ranges.

FAQ

Why do I have to create an user account?

I get this question pretty often. Two reasons

  • I wanted to have a shared account with my wife and storing everything online seemed like the easiest solution
  • Initially I planned on also having an online version for more and even deeper statistics. However I just didn’t have the time so far to build it

Why did you publish Confin?

For a long time Confin was just a private project and only used by myself and my wife. However couple of other people asked me I they can use it as well. At first I distributed Confin by sending the packaged app via E-Mail. But as the audience grows this approach was too obnoxious… And at that point I decided to publish it in the app store

GDPR

Confin stores following user specific data:

  • User name: Needed for login
  • E-Mail: Needed if you forget your password
  • Password: Is hashed with a strong one-way hashing algorithm (no way to decrypt it to the real password)

Every data is stored on servers in Germany.

You can find the full gdpr text here: Full GDPR Text

Conclusion

There are a lot of finance apps out there, and by now they are all pretty great (was a bit different when I started developing Confin 😉). I just like it when everything is exactly how I want it to be and how I need it.

If you use another finance app let me know which and why. I’m always interested in other peoples approaches.

If you have any ideas of cool features or feedback just leave a comment.
