Delta
If you've ever looked for a way to run scripts on Roblox mobile, you've probably heard of Delta. It's easily the most well-known Android executor out there and has been around since mid-2022. The Android APK version launched in 2023 and that's when it really blew up.
It runs on a custom engine called "Gloop" and scores 99% UNC with 100% sUNC, which is basically perfect. Most scripts that work on PC executors will work on Delta too. It comes with a built-in script hub and a mobile-friendly UI that's actually usable on a phone.
As of April 6, 2026, Delta is currently offline. Mobile executors sometimes take longer to update since they need to rebuild the APK.
The catch is it uses a key system, so you'll need to go through a key process (takes about a minute, involves ad pages) every 24 hours. That's how the developers make money since the executor itself is free.
Script Compatibility
100% sUNC is basically a perfect score. Delta can run pretty much anything you throw at it.

Our Take
If you're on Android, Delta is basically the only serious option. The UNC scores are insane for a mobile executor, the UI works well on phones, and it gets regular updates. The daily key system is the biggest downside since it adds friction every session. The fake download sites are also a real problem, so make sure you're getting it from the right place. Overall, it's impressive for what it is.
