Transform Your Phone into a Precision Leveling Tool! Over 450K users - 4.5 Star Average Rating Introducing the Super-Easy Level: Turn your device into a highly accurate bubble level (spirit level) with ease. Ideal for both DIY aficionados and professional builders, our app delivers unparalleled precision for any leveling task. Why Choose Super-Easy Level? Versatile Measurement Tools: Not only can you check the level and inclination of surfaces, but with our camera integration, measuring lengths becomes a breeze. Augmented Reality Features: Equipped with an augmented reality ruler and protractor for cutting-edge measurement accuracy. Simplicity at Its Best: Enjoy a user-friendly interface that makes navigation a piece of cake on any smartphone or tablet. Now on Apple Watch: Angle measurements appear live on your wrist. The Watch app mirrors your iPhone's mode and accent color in real time. In 1D mode, a full-screen artificial horizon tilts with your measured angle — choose degrees, slope %, or near-delta. In 2D mode, a dual-axis crosshair with a yaw compass ring tracks tilt on both axes simultaneously. Lock readings or save angles directly from your Watch; the last reading stays on screen even if the iPhone connection drops. Key Features: Ultra-Precise: Measures angles to the nearest tenth of a degree. Effortless Calibration: Simple one-touch calibration keeps accuracy at your fingertips. Clear Visual Display: Our interface is designed for clarity, ensuring your measurements are easy to read at a glance. Robust Toolset: Whether it's a quick DIY project or a professional job, our app is up to the task. Get Started in Seconds: Align your phone with a known level or vertical edge.

SpringSpec is a specialist spring rate calculator for motorsport suspension, built by race engineers for race engineers. Enter your corner weights, unsprung mass, and motion ratio — SpringSpec calculates wheel frequency, wheel rate, critical damping, and static deflection across every standard spring rate. It then recommends Soft, Recommended, and Hard options based on your intended use and drivetrain layout, and matches you to real parts from the Eibach ERS and Hyperco catalogues. KEY FEATURES — Dual-axle calculator with frequency, wheel rate, damping and deflection for every common spring rate — Drivetrain-aware balance: front-engine RWD, mid/rear-engine RWD, FWD — Target presets from Road to Race (1.3 Hz to 2.2 Hz) plus custom entry — Motion ratio entered as a decimal, squared internally — the correct engineering convention — Colour-coded frequency bands (Road, Road/Track, Race, Too Hard) — Built-in catalogue lookup for Eibach ERS and Hyperco springs, filtered by rate, free length, ID, and travel — Motion Ratio Guide with clear diagrams and two measurement methods — Save customer jobs locally with full inputs, results, and notes — Works in lbs/in, N/mm, or kg/mm NO ACCOUNTS. NO CLOUD. NO ADS. NO SUBSCRIPTIONS. All your data stays on your device. One-off purchase, updates via the App Store. DISCLAIMER SpringSpec provides engineering guidance based on the data you enter. Always verify inputs and outputs independently. Suspension setup affects vehicle safety — verify all choices against manufacturer specifications and, where appropriate, a qualified motorsport engineer. Published by RaceTracs Ltd, United Kingdom.
