Verdict
The clearest difference is price: Altimeter & Barometer at Free against CodeScaner's $2.99. Altimeter & Barometer also leads on iOS requirement (15 vs 26.0). CodeScaner's advantage is ads (none vs shown) and update cadence (monthly vs every 13 months). On in-app purchases and device support there is nothing between them.
