# congstar vs ja! mobil

The clearest difference is rating: congstar at 4.5 against ja! mobil's 3.6. congstar also leads on monetization model (free vs free with in-app purchases) and ratings volume (275 vs 24). On price, review sentiment, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

congstar holds the better App Store score, 4.5 against 3.6. That said, the two scores are not equally well evidenced: congstar has 275 ratings behind it against 24, so its average is the more settled of the two. Written reviews complicate that: 73% of congstar's written reviews are positive against 80% of ja! mobil's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on September 21, 2026 and September 23, 2026 respectively.
