# iNavX vs Shore Watch

The clearest difference is in-app purchases: Shore Watch at none against iNavX's 11. Shore Watch also leads on ads (none vs shown) and update cadence (every 2 days vs every 5 weeks). iNavX's advantage is chart position (#114 vs unranked) and iOS requirement (13.0 vs 15.1). On price and device support there is nothing between them.

Both are free to download. iNavX sells 11 in-app purchases, starting at $9.99 per month. Shore Watch asks for nothing beyond the download.

iNavX ships an update every 5 weeks, Shore Watch every 2 days. The most recent releases landed on October 21, 2026 and October 15, 2026 respectively.
