Verdict

The call

The clearest difference is review sentiment: Space at 78% against effectLang's 0%. Space also leads on ads (none vs shown) and update cadence (weekly vs every 3 weeks). effectLang's advantage is rating (5.0 vs 4.7). On price, in-app purchases, monetization model and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

effectLang holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Space has 34 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 78% of Space's written reviews are positive against 0% of effectLang's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Space ships an update weekly, effectLang every 3 weeks. Both last shipped on October 24, 2026.
