Verdict
The clearest difference is rating: Digi Chompers at 5.0 against NEC Master Exam Prep's 3.8. Digi Chompers also leads on monetization model (free with in-app purchases vs subscription) and update cadence (every 4 days vs every 2 weeks). NEC Master Exam Prep's advantage is ratings volume (5 vs 1). On price, ads and in-app purchases 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. NEC Master Exam Prep sells 2 in-app purchases, starting at $9.99 per month and Digi Chompers sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Digi Chompers holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: NEC Master Exam Prep has 5 ratings behind it against 1, so its average is the more settled of the two.
NEC Master Exam Prep ships an update every 2 weeks, Digi Chompers every 4 days. Both last shipped on October 16, 2026.
