Ivy Wallet: money manager

Ivy Wallet is a free money manager android app written using 100% Jetpack Compose and Kotlin. It's designed to help you track your personal finance with ease.

Imagine Ivy Wallet as a manual expense tracker that will replace the good old spreadsheet for managing your personal finance.

Track your expenses, fast and on-the-go! ⚡ Discover powerful insights about your spending.

Do you know? Ask yourself.

1. How much money do I have right now in all accounts combined?

2. How much did I spend this month and where?

3. How much money can I spend and still reach my financial goals?

A money manager app can help you answer these questions.

Ivy Wallet's biggest advantage is its UI/UX, simplicity, and customization which was recognized in the "Top/Best Android App in 2021/2022 charts" 10+ times by the YouTube tech community.

Architecture

We strive to keep our architecture "perfect" by putting software-design and code quality first.

We read a lot of books, CS papers, blogs and follow latest research in the industry.

Our goal is to make this repo the go-to project to learn about Android Development latest best practices and software architecture.

High-level view:

• Modular architecture
• FRP (Functional Reactive Programming)
• MVVM (Model-View-ViewModel)
• Onion Architecture (FP)

We've documented every major architecture decision as ADR (Architecture Decision Record) in docs/architecture. The best thing about ADRs is that you can see not only what went well but also what didn't!

We're also big on Computer Science that's why we're documenting every important algorithm used in the app. To see the algorithms in Ivy Wallet and their detailed space-time complexity analysis go to docs/algorithms.

If you're starting out with the Ivy Wallet project first have a look at our :core module.

We're also linking great learning materials (books, videos, articles, papers) in docs/resources 📚.

Have ideas/proposals how we can make our project better? Please, get in touch! 🚀
