Photo pitch measurement is now available with promotional code access, including codes already redeemed. Updated app launch compatibility for the latest iOS.

Updated the App Store screenshots and localized presentation. App functionality is unchanged.

Improved thread-standard search, bolt dimension diagrams, use-case search, unit conversion, comparison, and photo-based pitch measurement. This update also refines display stability and localized text.

Restored access to Apple's official promotion-code redemption from Settings. The secure Store code-entry screen remains available while the app-specific referral system is disabled. This update also includes stability improvements.

Improved thread and bolt references for engineering work. • Switch directly between coarse and fine pitch from the detail screen. • Clearer Thread Standards and Bolt Dimensions navigation, angle diagrams, and favorites. • Added low-head bolt tightening guidance and improved comparison-table readability.

Security and stability improvements. • Temporarily disabled the app-specific promotion-code entry and sharing feature while its anti-abuse protection is redesigned. • Strengthened network input validation and updated dependencies. • Thread search, photo pitch measurement, calculations, and one-time purchase and restore remain available.

New • Added Japanese, English, German, Spanish, French, Simplified Chinese, Korean and Brazilian Portuguese, grouped under one Language settings item. • Measure pitch from a photo: photograph a thread, then convert the crest spacing into pitch using the major diameter you measured, and see the closest standards. Measurement happens on your device and the image is never sent anywhere. • Thread-insert (STI) conversion: tap sizes and reference drills for metric, number and fractional-inch sizes (paid edition). • Thread trivia: commonly confused designations such as PT/PS, UNC/UNF and UNJ, organised by standard and reachable from search. • Calculated reference values for uncataloged sizes: search a size like “M54×1.5” (diameter × pitch) to see reference dimensions derived from the basic thread form (large M, Tr and MJ in the paid edition). Improved • Measure pitch from a photo: pitch can now always be converted by aligning the measurement lines manually, even when automatic reading has low confidence. The purchase screen also lists exactly what the paid edition adds. • More accurate candidates when searching by a measured major diameter, allowing for the fact that external threads measure slightly under the nominal size. • Fixed a flicker that appeared during the back swipe. • Fixed truncated dimension values and clarified that 1:16 is a diameter taper. • Fixed the Thread Trivia category layout. • Removed the dedicated tapping- and wood-screw page. • Removed the unclear down-arrow control beside the promotion-code field.

• Improved back navigation: swipe from the screen edge and the view now follows your finger, revealing the previous screen • Amazon product-search links now open directly in your browser • Stability and display improvements
