Verdict
The clearest difference is rating: View Source Premier at 4.1 against CodeDiff +'s 2.0. View Source Premier also leads on update cadence (every 3 weeks vs every 7 months) and ratings volume (27 vs 1). CodeDiff +'s advantage is price ($3.99 vs $6.99).

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
View Source Premier costs $6.99 and CodeDiff + $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.
View Source Premier holds the better App Store score, 4.1 against 2.0. That said, the two scores are not equally well evidenced: View Source Premier has 27 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 47% of View Source Premier's written reviews are positive against 50% of CodeDiff +'s, so the app with the better star average is not the one people write more warmly about.
View Source Premier ships an update every 3 weeks, CodeDiff + every 7 months. Both last shipped on September 23, 2026.
