# NAPA PROLink vs ALLDATA

The clearest difference is rating: ALLDATA at 3.5 against NAPA PROLink's 2.5. ALLDATA also leads on update cadence (every 5 weeks vs every 3 months). NAPA PROLink's advantage is monetization model (free vs subscription) and review sentiment (35% vs 10%). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ALLDATA holds the better App Store score, 3.5 against 2.5. That said, the two scores are not equally well evidenced: NAPA PROLink has 57 ratings behind it against 8, so its average is the more settled of the two. Written reviews complicate that: 35% of NAPA PROLink's written reviews are positive against 10% of ALLDATA's, so the app with the better star average is not the one people write more warmly about.

NAPA PROLink ships an update every 3 months, ALLDATA every 5 weeks. The most recent releases landed on October 22, 2026 and October 26, 2026 respectively.
