Verdict
The clearest difference is ratings volume: LeetCode at 694 against Embedded Systems+'s 2. LeetCode also leads on update cadence (every 11 days vs every 5 weeks). Embedded Systems+'s advantage is rating (5.0 vs 4.8). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Embedded Systems+ sells 6 in-app purchases, starting at $9.99 per month and LeetCode sells 2 in-app purchases, starting at $35.00 per month. Whichever you choose, the download price is not the number that matters.
Embedded Systems+ holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: LeetCode has 694 ratings behind it against 2, so its average is the more settled of the two.
Embedded Systems+ ships an update every 5 weeks, LeetCode every 11 days. The most recent releases landed on October 30, 2026 and November 9, 2026 respectively.
