RESPONSIVE HUD BLUEPRINT GALLERY โ€ข Explore professional control layouts tailored for every playstyle: Two-Thumb Pro, 3-Finger Claw, 4-Finger Gyro Hybrid, and Scoped Sniper setups. โ€ข True Responsive Tablet Morphing: Unlike standard mobile ports, our gallery dynamically recalculates geometry and shifts aspect ratios from 16:9 (iPhone) to wider 4:3 layouts when an iPad or large tablet class is selected. NATIVE IMMERSIVE EXPERIENCE โ€ข Feel every action with integrated iOS haptic vibration feedback engineered directly into the UI controls. โ€ข Custom audio cues and a distraction-free neon-on-black interface keep your eyes relaxed during late-night optimization sessions. 100% SAFE, STANDALONE & ANTI-CHEAT COMPLIANT Sadx FreeStyle is strictly an external mathematical calculation utility, training companion, and reference guide. โ€ข NO Game Interaction: This app does NOT interact with, modify, hook into, or alter any external game files, servers, or running memory. โ€ข NO Automation or Macros: We do not provide auto-clickers, floating overlays, macros, or cheats. All calculated sensitivity values and HUD layouts are designed to be manually applied by the player inside their preferred game settings. โ€ข NO Account Risk: Because the application operates entirely within its own isolated sandbox without tracking or game integration, it is 100% safe to use alongside popular battle royale titles like FF and other competitive mobile shooters.

About

DSFlex ECA

Read full description

DSFlex ECA is the official companion app for the DSFlex Ethanol Content Analyzer โ€” a precision Bluetooth sensor that measures the real ethanol content and temperature of the fuel in your tank. Built for flex fuel tunes, E85 conversions, and anyone running a blend of gasoline and ethanol, DSFlex ECA gives you accurate, real-time readings so you can tune with confidence. FEATURES - Live ethanol content (%) and fuel temperature, streamed over Bluetooth from your DSFlex sensor. - Blend Calculator with two modes โ€” Target Mix (hit a specific ethanol blend without topping off) and Fill Tank (top off completely using two fuels). - Customizable units โ€” Fahrenheit or Celsius, liters or gallons. - Set your local pump gas ethanol percentage and default tank size for accurate calculations. - Clean, simple interface built for quick glances while working on your vehicle. DSFlex ECA is a measurement and information tool. It does not tune your engine or control any vehicle system โ€” it gives you the accurate data you need to make your own tuning decisions. Requires a DSFlex Ethanol Content Analyzer sensor (sold separately).
