# Opensignal Speed Test Ad Free vs Tether Mobile

The clearest difference is review sentiment: Tether Mobile at 100% against Opensignal Speed Test Ad Free's 38%. Opensignal Speed Test Ad Free's advantage is rating (4.5 vs 2.0) and monetization model (free vs free with in-app purchases). On price, ads, in-app purchases and device support there is nothing between them.

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

Opensignal Speed Test Ad Free holds the better App Store score, 4.5 against 2.0. That said, the two scores are not equally well evidenced: Opensignal Speed Test Ad Free has 18K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 38% of Opensignal Speed Test Ad Free's written reviews are positive against 100% of Tether Mobile's, so the app with the better star average is not the one people write more warmly about.

Opensignal Speed Test Ad Free ships an update every 3 weeks, Tether Mobile every 2 months. The most recent releases landed on October 31, 2026 and October 24, 2026 respectively.
