### Cons

- Frequent language/translation problems: app defaults to Spanish, English translations and English examples are missing or hard to access.
- AI features sometimes fail or error; premium AI tools not functioning at times.
- Performance issues: laggy formula calculator and occasional UI glitches.
- Premium/license issues: reports of re-purchasing after deletion and gating important formulas behind premium.
