BaseMate

BaseMate makes levelling rectangular bases, platforms and work surfaces easier by telling you how much each corner needs to be adjusted. A conventional spirit level can tell you that a surface isn't level. BaseMate helps tell you what to do about it. Place your iPhone or iPad centrally near the edge of the surface, enter its width and depth, and BaseMate uses the device's motion sensors to calculate the adjustment required at each corner. Raise, Lower or Choose your reference Choose the approach that suits the job: • RAISE — BaseMate uses the highest corner as the reference and calculates how much the other corners need to be raised. Ideal when using shims, packers, adjustable feet or supporting material. • LOWER — BaseMate uses the lowest corner as the reference and calculates how much the other corners need to be lowered. Useful when lowering adjustable supports or determining how much material needs to be removed. • CHOOSE ANY CORNER — If one corner is fixed or cannot be moved, simply select it as the reference. BaseMate recalculates every other corner around that point, showing positive values for corners that need raising and negative values for those that need lowering. See the whole surface at a glance The base itself becomes the display. Each corner is shaded according to the correction required: • Red — too low • Blue — too high • Green — level within tolerance The strength of the colour indicates the degree of correction required, while calculated measurements show approximately how much each corner needs to move. Optional spoken guidance lets you concentrate on making adjustments without continually watching the screen. Ideal for : • Workbenches and tables • Shed and summerhouse bases • Greenhouse foundations • Cabinets and appliances • Decking frames and platforms • Hot-tub and spa bases • Machinery and workshop equipment • Garden structures • Other rectangular bases and platforms **Features include:** • Calculated adjustment measurements for all four corners • Raise to the highest corner • Lower to the lowest corner • Select any corner as a fixed reference • Positive and negative adjustment guidance • Clear high, low and level colour indication • Adjustable base width and depth • Metric and imperial measurements • Quick width and depth swapping when measuring from another side • Device-placement guidance • Calibration for the device and reference surface • Stabilised readings to reduce distracting movement • Optional spoken guidance • Support for iPhone and iPad • Works offline with no account required Less trial and error. More useful information. Whether you're packing beneath a workbench, adjusting appliance feet, levelling a shed base, trimming a support or positioning workshop equipment, BaseMate gives you a practical measurement for each corner so you know where to start. BaseMate uses your device's motion sensors. Results depend on correct calibration, placement and entered dimensions and are intended as practical adjustment guidance rather than certified surveying measurements. Always recheck the surface after making adjustments and use appropriate measuring equipment for safety-critical or precision installations.

Version 1.1 adds flexible reference-corner selection. The reviewer can: 1. Select Raise to use the highest corner as the reference. 2. Select Lower to use the lowest corner as the reference. 3. Tap any displayed corner to use it as a custom reference. 4. Observe that positive values indicate corners to raise and negative values indicate corners to lower. No account, login, external service or sample file is required. Place the device on a stable surface, calibrate it, enter the base dimensions and then tilt the device slightly to observe the adjustment calculations.
