Verdict
The clearest difference is rating: TechDraw min at 4.2 against Charting's 3.4. TechDraw min also leads on in-app purchases (none vs 1). Charting's advantage is ads (none vs shown) and update cadence (weekly vs every 4 months). On price, device support and iOS requirement there is nothing between them.
