Verdict

The call

The clearest difference is ads: Algorithms at none against Sololearn's shown. Algorithms also leads on review sentiment (91% vs 70%) and iOS requirement (12.0 vs 15.0). Sololearn's advantage is ratings volume (82K vs 101) and update cadence (every 2 weeks vs every 6 weeks). On price, rating, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Algorithms sells 1 one-off in-app purchase and Sololearn sells 12 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.7 for Algorithms against 4.8 for Sololearn. That said, the two scores are not equally well evidenced: Sololearn has 82K ratings behind it against 101, so its average is the more settled of the two. Written reviews are what separate them: 91% of Algorithms's written reviews are positive against 70% of Sololearn's.

UpkeepUpdate frequency

Algorithms ships an update every 6 weeks, Sololearn every 2 weeks. The most recent releases landed on August 24, 2026 and September 25, 2026 respectively.
