# Light GO 19x vs Go Challenger

The clearest difference is rating: Go Challenger at 4.7 against Light GO 19x's 3.7. Go Challenger also leads on update cadence (every 5 weeks vs every 3 months). Light GO 19x's advantage is ads (none vs shown) and monetization model (free vs free with in-app purchases). On price, ratings volume, in-app purchases and device support there is nothing between them.

Both are free to download. Light GO 19x sells 1 one-off in-app purchase and Go Challenger sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Go Challenger holds the better App Store score, 4.7 against 3.7. Both are backed by a comparable volume of ratings — 7 and 3 respectively. Written reviews complicate that: 75% of Light GO 19x's written reviews are positive against 58% of Go Challenger's, so the app with the better star average is not the one people write more warmly about.

Light GO 19x ships an update every 3 months, Go Challenger every 5 weeks. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
