# Lekh vs PureFlow

The clearest difference is in-app purchases: PureFlow at none against Lekh's 2. PureFlow also leads on rating (4.7 vs 4.2) and ratings volume (162 vs 15). Lekh's advantage is device support (4 vs 1). On price, update cadence, ads and iOS requirement there is nothing between them.

Both are free to download. Lekh sells 2 in-app purchases, starting at $3.99 per month. PureFlow asks for nothing beyond the download.

PureFlow holds the better App Store score, 4.7 against 4.2. That said, the two scores are not equally well evidenced: PureFlow has 162 ratings behind it against 15, so its average is the more settled of the two. Written reviews point the same way: 72% of Lekh's written reviews are positive against 85% of PureFlow's.

Lekh ships an update fortnightly, PureFlow weekly. The most recent releases landed on October 24, 2026 and October 23, 2026 respectively.
