👎🏼 Cons

Ads in Free Version: Free tier includes intermittent ads that can interrupt flow during quick calculations. Ad frequency increases with heavy usage unless upgraded. 📣

Some Advanced Tools Locked: Graphing and batch-processing features require a paid upgrade to access full functionality. Power users may find the paywall limiting for specialized tasks. 🔒

Limited Graphing: Graphing capabilities are basic compared to dedicated graphing apps and lack advanced plotting controls. Complex visual analysis may require third-party tools. 📉

No Cross-Device Sync on Free: Sync and cloud backup are reserved for premium plans, so history does not transfer automatically across devices on the free tier. Manual export is required for migration. 🔁

Occasional Permission Prompts: Location or contact-permission prompts appear for optional currency and sharing features, which can be disruptive. Permissions are optional but may be confusing for privacy-conscious users. ⚠️
