Verdict
The clearest difference is ads: RaspIoT at none against Basic Calculator+'s shown. RaspIoT also leads on iOS requirement (9.2 vs 15.0). Basic Calculator+'s advantage is update cadence (every 4 months vs every 25 months) and device support (4 vs 2). On price and in-app purchases there is nothing between them.
