# Estudylog vs Sum

The clearest difference is rating: Sum at 5.0 against Estudylog's 4.5. Sum also leads on review sentiment (100% vs 72%). Estudylog's advantage is update cadence (every 3 days vs every 3 weeks) and ratings volume (72 vs 2). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Estudylog sells 2 in-app purchases, starting at $3.99 per month and Sum sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Sum holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Estudylog has 72 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 72% of Estudylog's written reviews are positive against 100% of Sum's.

Estudylog ships an update every 3 days, Sum every 3 weeks. The most recent releases landed on November 8, 2026 and November 9, 2026 respectively.
