Verdict
The clearest difference is price: Auto101 Pro at Free against Piping DataBase's $3.99. Auto101 Pro also leads on rating (5.0 vs 2.0) and in-app purchases (none vs 1). Piping DataBase's advantage is chart position (#184 vs unranked) and iOS requirement (8.0 vs 16.0). On review sentiment, ads and device support there is nothing between them.
