Verdict

The call

The clearest difference is rating: iNavX at 4.8 against Ditch's 3.9. iNavX also leads on ratings volume (22K vs 22) and iOS requirement (13.0 vs 15.1). Ditch's advantage is ads (none vs shown) and review sentiment (64% vs 44%). On price, update cadence, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. iNavX sells 11 in-app purchases, starting at $9.99 per month and Ditch sells 2 in-app purchases, starting at $24.99 per year. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

iNavX holds the better App Store score, 4.8 against 3.9. That said, the two scores are not equally well evidenced: iNavX has 22K ratings behind it against 22, so its average is the more settled of the two. Written reviews complicate that: 44% of iNavX's written reviews are positive against 64% of Ditch's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iNavX ships an update every 5 weeks, Ditch monthly. The most recent releases landed on September 24, 2026 and August 4, 2026 respectively.
