A linear interpolation calculator designed for industrial commissioning engineers. It has the following features: - Displays large numbers for when you are out in the field commissioning. - Allows quickly swapping x and y coordinates; for example from 4-20mA -> 0-100% to 0-100% -> 4-20mA.
Sweep & Zone
This utility app helps field artillery personnel calculate firing data quickly and accurately. It reduces human error by computing changes in mils, deflections, and quadrants, allowing users to focus on critical tasks during high-stress situations.
- Fast and accurate firing data computation
- Reduces human error under stress
- Input changes in mils, deflections, and quadrants
- Calculates base deflection and quadrant
- Unlimited access with subscription

Verdict
The clearest difference is review sentiment: Sweep & Zone at 100% against Linear Interpolation Master's 63%. Sweep & Zone also leads on ads (none vs shown) and update cadence (every 5 weeks vs every 5 months). Linear Interpolation Master's advantage is ratings volume (176 vs 22) and iOS requirement (11.0 vs 17.0). On price, in-app purchases, monetization model and device support there is nothing between them.
