Verdict
The clearest difference is rating: Arcus VBT at 5.0 against Change's 4.6. Arcus VBT also leads on update cadence (every 8 days vs every 5 weeks) and review sentiment (100% vs 81%). Change's advantage is ratings volume (49 vs 3) and device support (3 vs 1). On price, ads, in-app purchases and monetization model 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. Change sells 12 in-app purchases, starting at $1.49 per month and Arcus VBT sells 6 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
Arcus VBT holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Change has 49 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 81% of Change's written reviews are positive against 100% of Arcus VBT's.
Change ships an update every 5 weeks, Arcus VBT every 8 days. The most recent releases landed on October 17, 2026 and October 15, 2026 respectively.
