# Sub3 vs OpenSub

Sub3 and OpenSub are too close to call on the numbers: across 6 compared parameters — price, update cadence, ads and in-app purchases among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. Sub3 sells 3 in-app purchases, starting at $2.99 per month and OpenSub sells 2 in-app purchases, starting at $9.99 per year. Whichever you choose, the download price is not the number that matters.

Sub3 ships an update every 9 days, OpenSub every 2 weeks. The most recent releases landed on October 28, 2026 and November 5, 2026 respectively.
