Verdict
The clearest difference is ads: SPENGA 2.0 at none against Cor4's shown. SPENGA 2.0 also leads on ratings volume (13K vs 5) and monetization model (free vs ad-supported). On price, rating, update cadence and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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 Cor4 against 5.0 for SPENGA 2.0. That said, the two scores are not equally well evidenced: SPENGA 2.0 has 13K ratings behind it against 5, so its average is the more settled of the two.
Cor4 ships an update monthly, SPENGA 2.0 every 5 weeks. The most recent releases landed on June 7, 2026 and September 24, 2026 respectively.
