User Reviews

Users praise the app for its comprehensive thread data, ease of use, and helpful features like profile drawings and calculators. However, multiple users highlight the need for imperial measurement units, inclusion of additional thread standards such as BSW and ANSI Unified, and improvements in data accuracy. Requests for better tapping hole size charts and English language support are also noted. Overall, the app is well-regarded but would benefit from expanded standards and measurement options.

Pros

Comprehensive thread information including BA specs, useful for model engineers and optical techs.
User-friendly and helpful at the workplace, appreciated by multiple users.
Includes thread profile drawings and a custom metric thread calculator.
Combines multiple similar apps into one, satisfying users' needs.
Fast and easy to use with essential thread identification information.

Cons

Lack of imperial measurement units and options, requested by several users.
Missing specific thread standards like BSW (British Standard Whitworth) and ANSI Unified threads, requested by multiple users.
Some thread data inconsistencies or inaccuracies reported (e.g., 3/8 pipe thread minor diameter).
Requests for hole size charts and tapping hole sizes to be included or reinstated.
Some language support issues; need for English language option.
