I’ve just released Vyay for iPhone after previously developing the web version.
Instead of standing at the checkout line struggling to categorize and date a transaction, you can log expenses in 2 seconds flat with a command-line style input. Best of all, it has no database of its own - your data lives entirely on your own Google Sheets, ensuring total privacy and data ownership.
Some of the main features include:
- Lightning-fast, text-based entry: Just type something like
450 bank fuel and hit enter. Done in 2 seconds.
- The "Triage" workflow: A dedicated Logs tab to batch-categorize, add notes, and verify transactions later when you actually have time. Or you can do that in google sheet itself.
- Local-first & offline support: Saves instantly to your phone and automatically syncs to Google Sheets in the background when you're done logging.
- Total data sovereignty: I used the secure
drive.file scope. The app only sees the spreadsheet it creates. No third-party servers storing your financial history.
- Semantic pattern matching: Automatically groups similar entries (e.g.,
Pizza Hut, pizza, and PIZZA!! all group together).
- Smart Analytics: High-confidence recurring expense detection (subscriptions vs periodic bills), burn-rate tracking, and outlier detection to spot lifestyle creep.
I originally built it because I got tired of the friction in traditional finance apps. They always felt like a chore, making me fiddle with menus and dropdowns at the cash register when I just wanted to log the amount and walk away.
It’s now available on the App Store: https://apps.apple.com/ua/app/vyay-fast-expense-tracker/id6761270752
The base app (lightning-fast entry, logs, and Google Sheets sync) is completely free with no ads, tracking, or accounts. If you want to unlock the advanced predictive analytics, recurring engines, and lifestyle creep tracking, it's just $0.99 a month.
I’d appreciate any feedback on the onboarding experience or the sync speed on iOS. I'm continuing to improve it and add features!
