# Therapeutic Guidelines vs Opioid Conversion Calculator

The clearest difference is in-app purchases: Therapeutic Guidelines at none against Opioid Conversion Calculator's 3. Therapeutic Guidelines also leads on rating (4.0 vs 3.7). Opioid Conversion Calculator's advantage is review sentiment (38% vs 6%) and update cadence (every 6 weeks vs every 4 months). On price, ads and device support there is nothing between them.

Both are free to download. Opioid Conversion Calculator sells 3 in-app purchases, starting at $3.99 per month. Therapeutic Guidelines asks for nothing beyond the download.

Therapeutic Guidelines holds the better App Store score, 4.0 against 3.7. Both are backed by a comparable volume of ratings — 4 and 17 respectively. Written reviews complicate that: 6% of Therapeutic Guidelines's written reviews are positive against 38% of Opioid Conversion Calculator's, so the app with the better star average is not the one people write more warmly about.

Therapeutic Guidelines ships an update every 4 months, Opioid Conversion Calculator every 6 weeks. The most recent releases landed on October 19, 2026 and October 9, 2026 respectively.
