Verdict

The call

The clearest difference is rating: AlgoApp at 4.7 against Scribd's 2.8. AlgoApp also leads on monetization model (free with in-app purchases vs subscription) and review sentiment (50% vs 14%). Scribd's advantage is chart position (#118 vs unranked). On price, ads and in-app purchases there is nothing between them.

Both are free to download. AlgoApp sells 4 in-app purchases, starting at $9.99 per month and Scribd sells 10 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
