## Review summary

While the app is praised for its speed, usefulness, and improved search function, multiple users report significant issues with an incomplete transistor database, lack of basic transistor info, and imperfect search filtering. Users seek better data accuracy and features like clearing previous search inputs to enhance usability.

### Pros

- App loads data quickly and operates fast.
- Contains a wide database of bipolar transistor information compared to other apps.
- Users find it generally useful for obtaining transistor data.
- Search function is working properly after recent improvements.
- Simple and easy to use, appreciated by users.

### Cons

- Database is incomplete, missing many FETs and widely-used transistors.
- Lacks basic information about transistor types like NPN and PNP.
- Search algorithm needs improvement to filter by parameters effectively and show all relevant results.
- App retains previous search data without an easy way to clear, causing interference during new searches.
- Some transistor data is incorrect or inconsistent, such as voltage specifications and duplicates in parameters.
