# Sullivan PDR Estimator vs TopGuru

The clearest difference is review sentiment: Sullivan PDR Estimator at 86% against TopGuru's 29%. Sullivan PDR Estimator also leads on rating (5.0 vs 3.5). TopGuru's advantage is ratings volume (414 vs 1) and chart position (#133 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Sullivan PDR Estimator sells 6 one-off in-app purchases and TopGuru sells 9 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

Sullivan PDR Estimator holds the better App Store score, 5.0 against 3.5. That said, the two scores are not equally well evidenced: TopGuru has 414 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 86% of Sullivan PDR Estimator's written reviews are positive against 29% of TopGuru's.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on November 1, 2026 and November 9, 2026 respectively.
