# Juno vs Undertone

The clearest difference is rating: Juno at 5.0 against Undertone's 4.5. Juno also leads on review sentiment (100% vs 75%) and update cadence (every 3 days vs every 5 days). Undertone's advantage is monetization model (ad-supported vs free with in-app purchases) and ratings volume (10 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Juno sells 10 in-app purchases, starting at $19.99 per month and Undertone sells 6 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.

Juno holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Undertone has 10 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of Juno's written reviews are positive against 75% of Undertone's.

Juno ships an update every 3 days, Undertone every 5 days. The most recent releases landed on October 8, 2026 and October 24, 2026 respectively.
