Verdict
The clearest difference is in-app purchases: Blue2Factor at none against Scientific Calculator's 4. Blue2Factor also leads on rating (5.0 vs 4.8). Scientific Calculator's advantage is ratings volume (17 vs 1) and update cadence (monthly vs every 2 months). On price, ads and device support there is nothing between them.
