I haven’t done an extensive search, but the ones that seem the best to me would be Thought Saver, UpLift, and Clarity CBT Journal. All three of these are from EA-aligned people and seem to be very evidence-based; Clarity is also very popular.
Meditation might be more approachable for people & is less medicalised. Headspace is the most-used and has the most evidence, but if your hypothetical friend wants something a bit less mushy both 10% Happier and Waking Up are really good (and are both doing something a bit different).
