# AutoArp vs LE05

The clearest difference is ads: AutoArp at none against LE05's shown. AutoArp also leads on review sentiment (82% vs 54%) and iOS requirement (10.0 vs 13.0). LE05's advantage is update cadence (every 6 weeks vs every 4 months) and ratings volume (139 vs 26). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. AutoArp sells 1 one-off in-app purchase and LE05 sells 4 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

AutoArp holds the better App Store score, 4.3 against 4.1. That said, the two scores are not equally well evidenced: LE05 has 139 ratings behind it against 26, so its average is the more settled of the two. Written reviews point the same way: 82% of AutoArp's written reviews are positive against 54% of LE05's.

AutoArp ships an update every 4 months, LE05 every 6 weeks. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
