DeltaMeasure – Precision Angle & Triangle Calculator DeltaMeasure lets you measure angles on a horizontal plane with ease and accuracy. Simply tap to set a start point, rotate your device, and capture the angle difference (Δ) in real time. The app instantly calculates adjacent and opposite triangle sides, so you can apply results directly in practical scenarios. Key Features: • Real-time angle measurement (Δ) on a horizontal plane • Tap-to-set START and capture the exact rotation angle • Triangle side calculations (adjacent & opposite) from your chosen distance • Manual entry mode to input your own angle and compare results • Save up to 4 measurements with quick access timestamps • Undo & Clear options to manage your data easily • Visual windrose display with dynamic red arc and precise pointer • Haptic feedback for every degree crossed (for tactile precision) • Works with both upright and flat device orientations DeltaMeasure is designed for anyone who needs fast, precise, and clear angle measurements — whether in geometry, field work, or real-world setups. Measure smarter. Calculate faster. Trust Δ.
