# BackTable vs PE Classifier

The clearest difference is ads: PE Classifier at none against BackTable's shown. PE Classifier also leads on monetization model (free vs ad-supported). BackTable's advantage is ratings volume (25 vs 1) and update cadence (fortnightly vs monthly). On price, rating, 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.

On the App Store both sit at effectively the same score — 5.0 for BackTable against 5.0 for PE Classifier. That said, the two scores are not equally well evidenced: BackTable has 25 ratings behind it against 1, so its average is the more settled of the two.

BackTable ships an update fortnightly, PE Classifier monthly. The most recent releases landed on September 30, 2026 and September 18, 2026 respectively.
