# PDRA Slips vs GoAlerts

The clearest difference is rating: GoAlerts at 4.9 against PDRA Slips's 3.7. GoAlerts also leads on in-app purchases (none vs 2) and ratings volume (278 vs 3). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. PDRA Slips sells 2 in-app purchases, starting at $4.99 per month. GoAlerts asks for nothing beyond the download.

GoAlerts holds the better App Store score, 4.9 against 3.7. That said, the two scores are not equally well evidenced: GoAlerts has 278 ratings behind it against 3, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

Both ship on a similar rhythm, roughly fortnightly. Both last shipped on October 24, 2026.
