# Letterboxd vs Undulge

The clearest difference is in-app purchases: Undulge at none against Letterboxd's 10. Undulge also leads on ads (none vs shown) and iOS requirement (15.1 vs 17.5). Letterboxd's advantage is update cadence (fortnightly vs every 2 months) and chart position (#18 vs unranked). On price and device support there is nothing between them.

Both are free to download. Letterboxd sells 9 in-app purchases, starting at $18.99 per year. Undulge asks for nothing beyond the download.

Letterboxd ships an update fortnightly, Undulge every 2 months. The most recent releases landed on November 10, 2026 and November 9, 2026 respectively.
