"Torque Calculator" is an ultra-simple tool that helps you quickly find the estimated tightening torque for various bolts. Whether you are working on cars, motorcycles, bicycles, or doing DIY projects, this app instantly provides you with a theoretical torque value when you are unsure how tight a bolt should be. [Key Features] ・Simple Mode: Just select the bolt diameter, strength, and lubrication status for an instant calculation! ・Advanced Mode: Direct input for custom torque coefficients and target preload. ・Unit Switching: Easily toggle between millimeters (mm) and inches (inch). ・Custom Input: Enter custom values for non-standard bolt diameters. Designed to be straightforward and distraction-free, making it the perfect companion for your garage or workshop. [Disclaimer & Important Notice] The "target torque" calculated by this app is a theoretical estimate based on standard mechanical engineering formulas. Actual appropriate torque values can vary significantly due to factors such as individual bolt variations, rust, degradation, lubrication, temperature, and tool calibration. When working on critical safety components (e.g., cars, motorcycles, bicycles, structural engineering), always prioritize the manufacturer's specified torque values found in official service manuals. The developer assumes no liability for any bolt breakage, parts damage, accidents, injuries, or any other losses resulting from the use of this application's calculations. Please use this tool at your own risk and with utmost attention to safety.

Verdict
The clearest difference is in-app purchases: Conversions at none against Torque Wrench Guide's 2. Conversions also leads on ads (none vs shown). Torque Wrench Guide's advantage is update cadence (daily vs every 2 weeks) and iOS requirement (16.6 vs 18.6). On price and device support there is nothing between them.
