# A vs nPTT

The clearest difference is ratings volume: nPTT at 111 against A's 18. nPTT also leads on device support (3 vs 1) and iOS requirement (13.0 vs 17.2). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. A sells 2 in-app purchases, starting at $99.99 per month and nPTT sells 2 in-app purchases, starting at $0.99 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 — 4.5 for A against 4.6 for nPTT. That said, the two scores are not equally well evidenced: nPTT has 111 ratings behind it against 18, so its average is the more settled of the two. Written reviews are what separate them: 38% of A's written reviews are positive against 41% of nPTT's.

A ships an update every 2 weeks, nPTT every 9 days. Both last shipped on September 22, 2026.
