# REK vs PO

The clearest difference is monetization model: PO at free against REK's free with in-app purchases. PO also leads on update cadence (every 2 days vs every 6 days) and device support (3 vs 1). On price, rating, review sentiment and ratings volume there is nothing between them.

Both are free to download. REK sells 1 one-off in-app purchase and PO sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for REK against 5.0 for PO. Both are backed by a comparable volume of ratings — 2 and 1 respectively. Written reviews split almost evenly too, at 100% and 100% positive.

REK ships an update every 6 days, PO every 2 days. The most recent releases landed on October 24, 2026 and October 31, 2026 respectively.
