# MultiGauge vs TunerView

The clearest difference is rating: TunerView at 3.1 against MultiGauge's 1.0. TunerView also leads on review sentiment (40% vs 17%) and ratings volume (40 vs 4). MultiGauge's advantage is in-app purchases (none vs 4) and update cadence (fortnightly vs every 6 weeks). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. TunerView sells 4 one-off in-app purchases. MultiGauge asks for nothing beyond the download.

TunerView holds the better App Store score, 3.1 against 1.0. That said, the two scores are not equally well evidenced: TunerView has 40 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 17% of MultiGauge's written reviews are positive against 40% of TunerView's.

MultiGauge ships an update fortnightly, TunerView every 6 weeks. The most recent releases landed on June 11, 2026 and August 31, 2026 respectively.
