# Synopsis vs AVIX

The clearest difference is monetization model: AVIX at free with in-app purchases against Synopsis's subscription. Synopsis's advantage is rating (4.7 vs 4.3) and update cadence (every 5 days vs every 11 days). On price, review sentiment, ratings volume and ads there is nothing between them.

Both are free to download. Synopsis sells 12 in-app purchases, starting at $5.39 per month and AVIX sells 13 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

Synopsis holds the better App Store score, 4.7 against 4.3. Both are backed by a comparable volume of ratings — 406 and 272 respectively. Written reviews complicate that: 50% of Synopsis's written reviews are positive against 58% of AVIX's, so the app with the better star average is not the one people write more warmly about.

Synopsis ships an update every 5 days, AVIX every 11 days. The most recent releases landed on October 25, 2026 and October 22, 2026 respectively.
