# MyDataHelps vs bub

The clearest difference is rating: MyDataHelps at 4.4 against bub's 3.7. MyDataHelps also leads on in-app purchases (none vs 5) and ratings volume (312 vs 12). bub's advantage is review sentiment (86% vs 45%) and update cadence (every 11 days vs monthly). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. bub sells 5 in-app purchases, starting at $4.99 per 7 days. MyDataHelps asks for nothing beyond the download.

MyDataHelps holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: MyDataHelps has 312 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 45% of MyDataHelps's written reviews are positive against 86% of bub's, so the app with the better star average is not the one people write more warmly about.

MyDataHelps ships an update monthly, bub every 11 days. Both last shipped on October 24, 2026.
