# Algebra vs Phylogenetic Tree View

The clearest difference is in-app purchases: Phylogenetic Tree View at none against Algebra's 10. Algebra's advantage is ads (none vs shown) and update cadence (every 4 months vs every 11 months). On price, device support and iOS requirement there is nothing between them.

Both are free to download. Algebra sells 10 in-app purchases, starting at $9.99 per month. Phylogenetic Tree View asks for nothing beyond the download.

Algebra ships an update every 4 months, Phylogenetic Tree View every 11 months. The most recent releases landed on September 22, 2026 and September 9, 2026 respectively.
