Verdict

The call

The clearest difference is price: Linear Interpolation Master at Free against Interp Calculator's $0.99. Linear Interpolation Master also leads on update cadence (every 5 months vs every 15 months) and iOS requirement (11.0 vs 15.0). Interp Calculator's advantage is in-app purchases (none vs 3) and ads (none vs shown). On device support there is nothing between them.
