Easy Budget Money Tracker Zeny
by Lemon LLC






Zeny has been around since 2014 and Lemon LLC keeps it quietly updated, most recently in June 2026. The pitch is blunt: no bank syncing, no receipt scanning, no account required. You open it, tap in a number, pick a category, and move on. At 41 MB it barely registers on your phone. That singular focus works well for people who want a spending diary rather than a financial dashboard, but the free tier does hold back some genuinely useful tools behind a paywall.
Speed and Simplicity Done Right
The one-handed quick input is the core selling point and it delivers. Logging an expense takes a handful of taps with no signup friction getting in the way. The built-in calculator means you can split a bill and log it without leaving the app. Pie charts per category and bar charts covering expenses and income give enough visual feedback to spot trends at a glance, and the year, month, week, and day breakdowns make it easy to scope a specific period without digging through menus.
Where the Free Tier Stops Short
Several features that feel like basics in 2024 sit behind the Zeny Premium subscription: search, data export, passcode or Touch ID lock, recurring entries, and cloud sync across devices. Running the app on a second phone means starting fresh unless you pay. The free version also carries ads, which is a fair trade-off for some users but worth knowing upfront. Bar charts are limited to the overall view at the free level, with per-category bar charts reserved for premium subscribers.
Who Will Actually Get Value Here
Zeny suits someone who wants a fast, low-commitment spending log and is comfortable manually entering every transaction. If you already use a bank app for balance tracking and just want a simple layer on top for category awareness, the free version is a reasonable fit. Power users who need search or multi-device access will likely hit the paywall quickly and should factor that cost into the decision before committing their data to the app long-term.
