# TempBox vs EraSpark AI

The clearest difference is rating: EraSpark AI at 5.0 against TempBox's 3.4. EraSpark AI also leads on iOS requirement (15.6 vs 18.0). TempBox's advantage is update cadence (every 2 weeks vs every 2 months) and ratings volume (7 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. TempBox sells 3 one-off in-app purchases and EraSpark AI sells 1 in-app purchase, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

EraSpark AI holds the better App Store score, 5.0 against 3.4. That said, the two scores are not equally well evidenced: TempBox has 7 ratings behind it against 1, so its average is the more settled of the two.

TempBox ships an update every 2 weeks, EraSpark AI every 2 months. The most recent releases landed on October 8, 2026 and October 1, 2026 respectively.
