## Review summary

EMA App is valued for showing current production and per-panel output with a clear data view, but users report reliability and UX problems. Recurrent issues include night mode not persisting, delayed or hidden data, frequent offline outages, and removal/degradation of per-panel data. Users also want better data history/export options. Overall, core monitoring is possible, but stability and feature regressions significantly hamper the experience.

### Pros

- Shows current production and per-panel output with monthly data snapshots.
- Data is presented in an easy-to-understand, attractive format.
- Includes equipment health/warranty information in the data view.
- Provides a snapshot of previous months' production for trend awareness.

### Cons

- Settings like night mode don’t stay saved or sync with the device; you must reapply them each time.
- Data is delayed and not real-time; there can be 10-15 minute lag and display issues requiring interaction to show data.
- The app frequently goes offline or is unreliable, often forcing users to check information on the website.
- Removal or degradation of per-panel/module data undermines core monitoring capabilities.
- Limited data history and export options (no CSV export; restricted time range) hinder long-term analysis.
