Verdict

The call

The clearest difference is in-app purchases: BaroNote at none against DustMap's 4. BaroNote also leads on ads (none vs shown) and update cadence (every 2 months vs every 5 months). DustMap's advantage is device support (3 vs 1) and iOS requirement (15 vs 17.0). On price there is nothing between them.
