Verdict
The clearest difference is in-app purchases: Regal TMS at none against Calculator Smart's 3. Regal TMS also leads on ads (none vs shown) and update cadence (every 10 days vs every 4 months). Calculator Smart's advantage is device support (6 vs 2) and iOS requirement (13.0 vs 15.1). On price there is nothing between them.
