Verdict
The clearest difference is in-app purchases: ND Easy at none against Long Exposure Calculator's 6. ND Easy also leads on ads (none vs shown) and update cadence (every 5 weeks vs every 19 months). Long Exposure Calculator's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 17.0). On price there is nothing between them.
