Ultra Simple Expense Log
An expense app built for one fast action: enter an amount and record it. Extra input stays optional, while the dashboard is designed to help you notice patterns later.
Overview
What kind of app it is
It is made for people who stop using complicated budgeting apps. You can record an amount first, then add a category or note later if you want. Data stays on the device.
- The recording flow is intentionally short.
- Categories stay lightweight and optional.
- Local-first storage is the default approach.
- The app is now live on the App Store.
- The support and privacy pages are already published.
- This page now includes the App Store link and QR code.
How To Use
How it works
The default flow is short: enter an amount, record it, and add detail only when it helps.
The input is ready right after launch. Currency and closing day can be set up in advance.
Save immediately, or add a category and note if you want more detail on that entry.
Use history and the dashboard to see when and how much you tend to spend.
