# DigiDecoder vs 73 by N0AGI

The clearest difference is rating: 73 by N0AGI at 5.0 against DigiDecoder's 4.5. DigiDecoder's advantage is ratings volume (8 vs 1) and device support (3 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. DigiDecoder sells 2 in-app purchases, starting at $2.99 per month and 73 by N0AGI sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

73 by N0AGI holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: DigiDecoder has 8 ratings behind it against 1, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly weekly. Both last shipped on November 5, 2026.
