Verdict
The clearest difference is in-app purchases: JSA Tracker at none against iNavX's 11. JSA Tracker also leads on ads (none vs shown) and update cadence (every 4 days vs every 5 weeks). iNavX's advantage is chart position (#107 vs unranked). On price and device support there is nothing between them.
