# Zero vs Ask Baseline

The clearest difference is ads: Zero at none against Ask Baseline's shown. Ask Baseline's advantage is ratings volume (28 vs 1) and update cadence (every 9 days vs every 3 weeks). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Zero sells 3 in-app purchases, starting at $1.99 per month and Ask Baseline sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 5.0 for Zero against 5.0 for Ask Baseline. That said, the two scores are not equally well evidenced: Ask Baseline has 28 ratings behind it against 1, so its average is the more settled of the two.

Zero ships an update every 3 weeks, Ask Baseline every 9 days. The most recent releases landed on October 16, 2026 and October 24, 2026 respectively.
