Verdict
The clearest difference is review sentiment: Apex Stacked at 100% against Volt's 75%. Apex Stacked also leads on rating (5.0 vs 4.7). Volt's advantage is ratings volume (17K vs 1). On price, update cadence, ads 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. Volt sells 10 in-app purchases, starting at $9.99 per month and Apex Stacked sells 1 in-app purchase, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.
Apex Stacked holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Volt has 17K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 75% of Volt's written reviews are positive against 100% of Apex Stacked's.
Volt ships an update every 5 days, Apex Stacked every 8 days. The most recent releases landed on October 26, 2026 and October 18, 2026 respectively.
