# Running Slimkit vs Python PTS

Running Slimkit's advantage is ratings volume (87K vs 9). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Running Slimkit sells 10 in-app purchases, starting at $8.99 per month and Python PTS sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Python PTS holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Running Slimkit has 87K ratings behind it against 9, so its average is the more settled of the two.
