# LL2Link vs TopGuru

The clearest difference is rating: TopGuru at 3.5 against LL2Link's 3.0. TopGuru also leads on ratings volume (409 vs 2) and update cadence (every 3 weeks vs every 3 months).

Both are free to download. TopGuru sells 21 in-app purchases, starting at $9.99 per month. LL2Link asks for nothing beyond the download.

TopGuru holds the better App Store score, 3.5 against 3.0. That said, the two scores are not equally well evidenced: TopGuru has 409 ratings behind it against 2, so its average is the more settled of the two.
