# iNavX vs Back

The clearest difference is rating: iNavX at 4.8 against Back's 3.6. iNavX also leads on update cadence (every 5 weeks vs every 20 months) and ratings volume (22K vs 17). Back's advantage is ads (none vs shown) and iOS requirement (8.0 vs 13.0). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. iNavX sells 11 in-app purchases, starting at $9.99 per month and Back sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

iNavX holds the better App Store score, 4.8 against 3.6. That said, the two scores are not equally well evidenced: iNavX has 22K ratings behind it against 17, so its average is the more settled of the two. Written reviews point the same way: 44% of iNavX's written reviews are positive against 41% of Back's.

iNavX ships an update every 5 weeks, Back every 20 months. The most recent releases landed on October 16, 2026 and October 5, 2026 respectively.
