# Spikko vs String

Spikko and String both sit at 3.7 stars, but that hides the real split: 69% of String's written reviews are positive against 29% of Spikko's. String also leads on in-app purchases (none vs 10) and ratings volume (62 vs 7). Spikko's advantage is iOS requirement (9.0 vs 15.0). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Spikko sells 10 in-app purchases, starting at $3.99 per month. String asks for nothing beyond the download.

Spikko holds the better App Store score, 3.7 against 3.5. That said, the two scores are not equally well evidenced: String has 62 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 29% of Spikko's written reviews are positive against 69% of String's, so the app with the better star average is not the one people write more warmly about.

Spikko ships an update every 6 weeks, String every 2 months. Both last shipped on October 24, 2026.
