# Space vs effectLang

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.

Both are free to download. Space sells 6 in-app purchases, starting at $4.99 per month and effectLang sells 2 in-app purchases, starting at $3.49 per month. Whichever you choose, the download price is not the number that matters.

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.

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