# impf.app vs STIKO

The clearest difference is in-app purchases: STIKO at none against impf.app's 2. STIKO also leads on rating (4.8 vs 4.5) and review sentiment (61% vs 43%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. impf.app sells 2 in-app purchases, starting at $0.99 per month. STIKO asks for nothing beyond the download.

STIKO holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: STIKO has 20 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 43% of impf.app's written reviews are positive against 61% of STIKO's.

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 10, 2026 and October 12, 2026 respectively.
