About

ToleranceLab

This app assists engineers in selecting and understanding ISO 286 fits for mechanical designs. It calculates clearance or interference based on nominal size and basis classes, providing visual representations of resulting diameters. The tool also estimates contact pressure and stress for press fits and includes a reference guide for definitions and recommendations.

Highlights
  • ISO 286 fit selection
  • Hole/shaft basis class calculation
  • Clearance/interference visualization
  • Guided fit intent picker
  • Press fit stress estimation
  • Metric/imperial unit switching

ToleranceLab helps engineers pick ISO 286 fits and understand what those selections mean in the real world. Enter a nominal size, choose hole- or shaft-basis classes, and get clearance/interference results with a simple visual that labels the resulting diameters. Use the guided fit intent picker to match common engineering goals (free running, locational, transition, or interference) and jump into the built-in reference guide for definitions and ISO fit recommendations. When a press fit is detected, ToleranceLab estimates contact pressure and axial force using selectable compliance models and material data, with warnings and assumptions shown alongside results. Switch between metric and imperial units, explore fit classes quickly, and keep a practical reference at hand for design and manufacturing decisions. Disclaimer: ToleranceLab is provided as a general engineering reference tool only. All results and calculations are estimates based on standard formulas, assumptions, and user-supplied inputs. The app does not provide professional engineering, design, or safety advice and is not a substitute for independent analysis, validation, or review by a qualified engineer. To the maximum extent permitted by law, the developer assumes no liability for errors, omissions, or outcomes resulting from the use of this app. Users are solely responsible for verifying results and ensuring suitability for their specific application and compliance with applicable standards and regulations.

Bluetooth & Tracker Detector Protect your privacy. SafeScan detects hidden Bluetooth trackers, unknown devices, and suspicious electronics around you in real time. -- BLUETOOTH SCANNER -- Scan your surroundings for all nearby Bluetooth devices. SafeScan identifies AirTags, Samsung SmartTags, Tile, Chipolo, Pebblebee, Flipper Zero, and other BLE devices. Each device is displayed with signal strength, estimated distance, and detection frequency so you always know what is around you. -- SMART RISK ASSESSMENT -- Every detected device is analyzed by a built-in risk engine. SafeScan evaluates tracker signatures, unnamed broadcasts, signal proximity, duration of presence, and repeated detections to assign a clear risk level: Safe, Suspicious, or Potential Tracker. You get a plain explanation of why each device was flagged, not just a label. -- PRECISION TRACKER -- Found a suspicious device? Use the Precision Tracker to locate it physically. A live signal gauge shows your proximity percentage in real time, with estimated distance in meters. Sound and haptic feedback guide you as you walk closer. Move slowly, watch the percentage increase, and pinpoint the exact location. -- MAGNETIC FIELD SCANNER -- Go beyond Bluetooth. The Mag Scan feature uses your phone's magnetometer to detect hidden electronic devices such as cameras, recording equipment, and other electronics concealed in walls, bags, or furniture. A real-time graph displays field magnitude with baseline comparison and anomaly alerts when readings spike above normal levels. -- DEVICE DETAILS & HISTORY -- Tap any device to see full details: device type, signal strength, MAC address, manufacturer data, first seen time, and a signal history chart. Review your scan history to track patterns over time. -- WHITELIST & SAFE LIST -- Mark your own devices and trusted accessories as safe. Whitelisted devices are excluded from alerts so you only see real threats. -- KEY FEATURES -- Real-time Bluetooth radar with animated pulse display Detects AirTag, SmartTag, Tile, Chipolo, Pebblebee, Flipper Zero Point-based risk engine with clear explanations Precision tracking with live signal gauge and distance meter Sound and haptic feedback for locating devices Magnetic field scanner for hidden cameras and electronics Real-time signal graphs and charts Scan history and device logging Whitelist for your own trusted devices Works offline, no account required -- PRIVACY -- SafeScan runs entirely on your device. No data is sent to any server. No account is needed. Your scans and history stay private. --Subscription-- Payment will be charged to your iTunes Account at confirmation of purchase. Subscription automatically renews unless auto-renew is turned off at least 24 hours before the end of the current period. Your account will be charged for renewal within 24 hours prior to the end of the current period.

Verdict

The call

The clearest difference is price: Tracker Detector ° at Free against ToleranceLab's $2.99. Tracker Detector ° also leads on ratings volume (79 vs 3) and update cadence (every 3 months vs every 8 months). ToleranceLab's advantage is in-app purchases (none vs 2) and rating (5.0 vs 4.7). On ads, device support and iOS requirement there is nothing between them.
