Verdict
The clearest difference is in-app purchases: Toolkit at none against ThemeCalc's 17. Toolkit also leads on ads (none vs shown) and iOS requirement (12.0 vs 18.0). ThemeCalc's advantage is update cadence (every 6 days vs every 50 months). On price and device support there is nothing between them.
