# SLYFONE vs Nextline

SLYFONE and Nextline both sit at 4.6 stars, but that hides the real split: 78% of Nextline's written reviews are positive against 24% of SLYFONE's. Nextline also leads on ads (none vs shown) and update cadence (fortnightly vs every 6 weeks). SLYFONE's advantage is monetization model (free with in-app purchases vs subscription) and iOS requirement (15.0 vs 17.0). On price, rating, in-app purchases and device support there is nothing between them.

Both are free to download. SLYFONE sells 7 in-app purchases, starting at $14.99 per 3 months and Nextline sells 7 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for SLYFONE against 4.7 for Nextline. That said, the two scores are not equally well evidenced: Nextline has 9.5K ratings behind it against 777, so its average is the more settled of the two. Written reviews are what separate them: 24% of SLYFONE's written reviews are positive against 78% of Nextline's.

SLYFONE ships an update every 6 weeks, Nextline fortnightly. The most recent releases landed on October 27, 2026 and October 28, 2026 respectively.
