# codeSpark vs Charge the Robot

The clearest difference is update cadence: codeSpark at fortnightly against Charge the Robot's every 4 months. codeSpark also leads on ratings volume (41K vs 63) and rating (4.6 vs 4.3). Charge the Robot's advantage is review sentiment (70% vs 52%) and iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. codeSpark sells 11 in-app purchases, starting at $3.99 per month and Charge the Robot sells 4 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.

codeSpark holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: codeSpark has 41K ratings behind it against 63, so its average is the more settled of the two. Written reviews complicate that: 52% of codeSpark's written reviews are positive against 70% of Charge the Robot's, so the app with the better star average is not the one people write more warmly about.

codeSpark ships an update fortnightly, Charge the Robot every 4 months. The most recent releases landed on September 26, 2026 and September 4, 2026 respectively.
