# Advance Professional vs ALLDATA

The clearest difference is monetization model: Advance Professional at ad-supported against ALLDATA's subscription. Advance Professional also leads on review sentiment (24% vs 10%) and ratings volume (28 vs 8). ALLDATA's advantage is rating (3.5 vs 3.0) and ads (none vs shown). On price, 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 3.0. Both are backed by a comparable volume of ratings — 28 and 8 respectively. Written reviews complicate that: 24% of Advance Professional'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.

Advance Professional ships an update every 6 months, ALLDATA every 5 weeks. The most recent releases landed on October 23, 2026 and October 26, 2026 respectively.
