# CT Registry Test Pro vs MRI Plan

The clearest difference is ads: MRI Plan at none against CT Registry Test Pro's shown. MRI Plan also leads on review sentiment (100% vs 72%) and update cadence (fortnightly vs every 2 months). CT Registry Test Pro's advantage is ratings volume (214 vs 6). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. CT Registry Test Pro sells 1 one-off in-app purchase and MRI Plan sells 2 in-app purchases, starting at $19.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.9 for CT Registry Test Pro against 5.0 for MRI Plan. That said, the two scores are not equally well evidenced: CT Registry Test Pro has 214 ratings behind it against 6, so its average is the more settled of the two. Written reviews are what separate them: 72% of CT Registry Test Pro's written reviews are positive against 100% of MRI Plan's.

CT Registry Test Pro ships an update every 2 months, MRI Plan fortnightly. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
