## Review summary

The app is valued by some for wireless charging tests and long-term baseline data, and a few users report helpful developer support. However, it suffers frequent reliability issues after iOS updates (notably iOS 17), shows inaccurate wattage readings, and tests often stall or never finish. Buyers feel misled about functionality due to platform limitations, and maintenance appears lacking. A subset still uses it for baseline measurements, but overall sentiment is dominated by reliability concerns.

### Pros

- Great for testing wireless charging and comparing chargers/cables; provides data you can reference later for baselines.
- Helps establish long-term baseline measurements of battery charging, useful as devices age.
- A keeper for some users who want concrete charging information despite flaws.
- Some users report responsive support from the developers when issues arise.

### Cons

- Incompatibility with iOS updates; app stops working or shows incorrect results after iOS 16/17.
- Wattage readings are often wrong or extremely low (around 1W), not reflecting actual charging.
- Tests stall or never finish, with little progress indication.
- Post-purchase misrepresentation; platform limitations limit functionality after purchase.
- App appears not to be maintained/updated for new devices/OS versions.
