# Hexd vs Sum

The clearest difference is in-app purchases: Hexd at none against Sum's 1. Hexd also leads on ads (none vs shown) and ratings volume (7 vs 1). Sum's advantage is update cadence (every 3 days vs every 9 days). On price, rating and device support there is nothing between them.

Both are free to download. Sum sells 1 in-app purchase, starting at $1.99 per month. Hexd asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.9 for Hexd against 5.0 for Sum. That said, the two scores are not equally well evidenced: Hexd has 7 ratings behind it against 1, so its average is the more settled of the two.

Hexd ships an update every 9 days, Sum every 3 days. The most recent releases landed on October 16, 2026 and October 13, 2026 respectively.
