Verdict

The call

The clearest difference is rating: Fluid Mechanics Calc at 5.0 against Beam Engineering lite's 4.4. Fluid Mechanics Calc also leads on in-app purchases (none vs 1) and ads (none vs shown). Beam Engineering lite's advantage is update cadence (every 5 months vs every 22 months) and ratings volume (32 vs 3). On price, device support and iOS requirement there is nothing between them.
