# Coach Kelly vs 4TRAINER

Coach Kelly and 4TRAINER 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. Coach Kelly sells 1 in-app purchase, starting at $99.99 per month and 4TRAINER sells 4 in-app purchases, starting at $49.99 per month. Whichever you choose, the download price is not the number that matters.
