# Zapptive vs OS One

The clearest difference is in-app purchases: Zapptive at none against OS One's 3. Zapptive also leads on ratings volume (5 vs 1) and iOS requirement (13.0 vs 26.0). OS One's advantage is ads (none vs shown) and update cadence (every 4 days vs every 2 weeks). On price, rating and device support there is nothing between them.

Both are free to download. OS One sells 3 in-app purchases, starting at $4.99 per month. Zapptive asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Zapptive against 5.0 for OS One. That said, the two scores are not equally well evidenced: Zapptive has 5 ratings behind it against 1, so its average is the more settled of the two.

Zapptive ships an update every 2 weeks, OS One every 4 days. The most recent releases landed on November 4, 2026 and October 31, 2026 respectively.
