# Double Holo vs CollectorBased

The clearest difference is ratings volume: Double Holo at 1.4K against CollectorBased's 2. Double Holo also leads on update cadence (weekly vs every 3 weeks) and chart position (#16 vs #191). CollectorBased's advantage is rating (5.0 vs 4.7). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Double Holo sells 12 in-app purchases, starting at $2.99 per 7 days and CollectorBased sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

CollectorBased holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Double Holo has 1.4K ratings behind it against 2, so its average is the more settled of the two.

Double Holo ships an update weekly, CollectorBased every 3 weeks. Both last shipped on October 25, 2026.
