Verdict
The clearest difference is review sentiment: Memorize Texts at 80% against i's 43%. Memorize Texts also leads on ads (none vs shown) and rating (4.6 vs 4.2). i's advantage is update cadence (every 6 days vs every 5 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.
