# Candle vs Invisible String

The clearest difference is review sentiment: Invisible String at 100% against Candle's 68%. Invisible String also leads on rating (5.0 vs 4.8). Candle's advantage is ratings volume (11K vs 2) and chart position (#159 vs unranked). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Candle sells 24 in-app purchases, starting at $3.99 per 7 days and Invisible String sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Invisible String holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Candle has 11K ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 68% of Candle's written reviews are positive against 100% of Invisible String's.

Candle ships an update fortnightly, Invisible String every 3 weeks. The most recent releases landed on October 17, 2026 and October 7, 2026 respectively.
