Verdict
The clearest difference is rating: Echo.ai at 5.0 against Clinical Research Pro Test's 1.0. Echo.ai also leads on update cadence (every 5 days vs every 3 months) and ratings volume (7 vs 1). Clinical Research Pro Test's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Clinical Research Pro Test sells 4 in-app purchases, starting at $9.99 per 7 days and Echo.ai sells 2 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
Echo.ai holds the better App Store score, 5.0 against 1.0. That said, the two scores are not equally well evidenced: Echo.ai has 7 ratings behind it against 1, so its average is the more settled of the two.
