Verdict
The clearest difference is in-app purchases: Trackisi at none against Now Altimeter's 3. Trackisi also leads on update cadence (every 2 weeks vs monthly) and iOS requirement (15.0 vs 17.0). Now Altimeter's advantage is ads (none vs shown). On price and device support there is nothing between them.
