# BigPlan vs Cal Dedup

The clearest difference is rating: BigPlan at 5.0 against Cal Dedup's 1.0. BigPlan also leads on update cadence (every 2 weeks vs every 2 months) and ratings volume (5 vs 1). Cal Dedup's advantage is monetization model (free vs free with in-app purchases) and iOS requirement (13.0 vs 18.5). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. BigPlan sells 1 one-off in-app purchase and Cal Dedup sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

BigPlan holds the better App Store score, 5.0 against 1.0. That said, the two scores are not equally well evidenced: BigPlan has 5 ratings behind it against 1, so its average is the more settled of the two.

BigPlan ships an update every 2 weeks, Cal Dedup every 2 months. The most recent releases landed on October 30, 2026 and October 31, 2026 respectively.
