Verdict
The clearest difference is ratings volume: Chegg Study at 205K against Sumigi's 166. Chegg Study also leads on review sentiment (20% vs 0%) and chart position (#63 vs unranked).

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. Chegg Study sells 4 in-app purchases, starting at $15.99 per month and Sumigi sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.7 for Chegg Study against 4.8 for Sumigi. That said, the two scores are not equally well evidenced: Chegg Study has 205K ratings behind it against 166, so its average is the more settled of the two. Written reviews are what separate them: 20% of Chegg Study's written reviews are positive against 0% of Sumigi's.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 27, 2026 and September 25, 2026 respectively.
