# AnSo vs Guide Dose

The clearest difference is review sentiment: Guide Dose at 86% against AnSo's 39%. Guide Dose also leads on update cadence (every 5 days vs fortnightly). AnSo's advantage is chart position (#88 vs unranked) and iOS requirement (13.0 vs 15.5). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. AnSo sells 4 in-app purchases, starting at $0.49 per month and Guide Dose sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

AnSo ships an update fortnightly, Guide Dose every 5 days. The most recent releases landed on September 27, 2026 and September 16, 2026 respectively.
