Verdict

The call

The clearest difference is rating: Bubble Level at 4.5 against Redodo MPPT's 3.3. Bubble Level also leads on update cadence (weekly vs every 7 months) and ratings volume (702 vs 3). Redodo MPPT's advantage is in-app purchases (none vs 11) and ads (none vs shown). On price and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Bubble Level holds the better App Store score, 4.5 against 3.3. That said, the two scores are not equally well evidenced: Bubble Level has 702 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 41% of Bubble Level's written reviews are positive against 67% of Redodo MPPT's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Bubble Level ships an update weekly, Redodo MPPT every 7 months. The most recent releases landed on September 24, 2026 and June 6, 2026 respectively.
