# REST API Client vs PostX

The clearest difference is rating: REST API Client at 4.3 against PostX's 3.0. REST API Client also leads on update cadence (every 3 weeks vs every 3 months) and iOS requirement (14.0 vs 17.6). PostX's advantage is ads (none vs shown) and chart position (#186 vs unranked). On price, ratings volume, in-app purchases and monetization model there is nothing between them.

Both are free to download. REST API Client sells 1 one-off in-app purchase and PostX sells 3 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

REST API Client holds the better App Store score, 4.3 against 3.0. Both are backed by a comparable volume of ratings — 6 and 10 respectively.

REST API Client ships an update every 3 weeks, PostX every 3 months. The most recent releases landed on September 21, 2026 and September 28, 2026 respectively.
