# Krumbit vs NerdSip

The clearest difference is in-app purchases: Krumbit at none against NerdSip's 6. Krumbit also leads on review sentiment (94% vs 67%). NerdSip's advantage is rating (4.8 vs 4.5) and ratings volume (119 vs 15). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. NerdSip sells 6 in-app purchases, starting at $3.99 per month. Krumbit asks for nothing beyond the download.

NerdSip holds the better App Store score, 4.8 against 4.5. That said, the two scores are not equally well evidenced: NerdSip has 119 ratings behind it against 15, so its average is the more settled of the two. Written reviews complicate that: 94% of Krumbit's written reviews are positive against 67% of NerdSip's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on October 6, 2026 and October 12, 2026 respectively.
