# AD DSP vs GT Launch

The clearest difference is review sentiment: AD DSP at 100% against GT Launch's 50%. GT Launch's advantage is rating (4.0 vs 2.3) and update cadence (every 5 days vs every 13 months). On price, ratings volume, 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.

GT Launch holds the better App Store score, 4.0 against 2.3. Both are backed by a comparable volume of ratings — 6 and 4 respectively. Written reviews complicate that: 100% of AD DSP's written reviews are positive against 50% of GT Launch's, so the app with the better star average is not the one people write more warmly about.

AD DSP ships an update every 13 months, GT Launch every 5 days. The most recent releases landed on October 14, 2026 and October 2, 2026 respectively.
