LayMatic lets you adjust the factory air suspension of compatible Mercedes-Benz vehicles—right from your iPhone. Set the perfect stance for daily driving, photo shoots, or track days, then restore stock height anytime. No permanent wiring or coding: plug in, adjust, unplug. Requires the LayMatic OBD-II dongle (sold separately). What you can do Lower in seconds: Easy Mode adjusts all four corners; Front/Back controls axles; Manual enables per-wheel fine-tuning. Save & restore: Your vehicle’s original values are backed up on first connect so you can return to stock anytime. Multiple vehicles: One Key licenses one car; add additional Keys to enable more cars in your garage. Non-invasive setup: No cutting, no “lowering links,” and no permanent wiring. How it works Create an account and sign in. Plug the LayMatic OBD-II dongle into the OBD port (under the steering wheel on most Mercedes-Benz models). Open the app and connect; on first connection you’ll assign a Key to the vehicle. Adjust height using Easy, Front/Back, or Manual modes. Unplug the dongle when you’re done. Compatibility Works with most Mercedes-Benz models equipped with factory air suspension (e.g., AIRMATIC, Air Body Control). Not compatible with hydraulic systems such as Active Body Control (ABC)/Magic Body Control. For the latest list of supported models, see our compatibility page on the LayMatic website. Safety & legal Use only when parked on a level surface with the parking brake engaged. Do not operate while driving. Ensure any changes comply with your local laws and inspection requirements (e.g., TÜV). Adjustments are reversible, but may affect warranty or assistance; use at your own risk.

Verdict

The call

The clearest difference is price: LayMatic at Free against Stone ID's $5.99. Stone ID's advantage is ads (none vs shown) and iOS requirement (10.0 vs 12). On in-app purchases and device support there is nothing between them.
