Verdict

The call

The clearest difference is monetization model: Studio Era at free with in-app purchases against Built With Science+'s subscription. Studio Era also leads on chart position (#123 vs unranked). Built With Science+'s advantage is rating (4.8 vs 4.6) and update cadence (fortnightly vs every 5 weeks). On price, review sentiment, ads and in-app purchases there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Built With Science+ sells 4 in-app purchases, starting at $29.99 per month and Studio Era sells 9 in-app purchases, starting at $29.00 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Built With Science+ holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Built With Science+ has 5.1K ratings behind it against 599, so its average is the more settled of the two. Written reviews complicate that: 80% of Built With Science+'s written reviews are positive against 82% of Studio Era's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Built With Science+ ships an update fortnightly, Studio Era every 5 weeks. The most recent releases landed on October 31, 2026 and October 30, 2026 respectively.
