# BT1000 vs Battery Asst

The clearest difference is rating: BT1000 at 5.0 against Battery Asst's 3.7. Battery Asst's advantage is review sentiment (20% vs 0%) and ratings volume (9 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

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

BT1000 holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: Battery Asst has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 0% of BT1000's written reviews are positive against 20% of Battery Asst's, so the app with the better star average is not the one people write more warmly about.

BT1000 ships an update every 5 weeks, Battery Asst monthly. The most recent releases landed on September 23, 2026 and October 3, 2026 respectively.
