Many pregnant women use pregnancy related mHealth (PRmHealth) applications, encompassing a variety of pregnancy apps and wearables. These are mostly directed at supporting a healthier fetal development. In this article we argue that the increasing dominance of PRmHealth stands in want of empirical knowledge affirming its beneficence in terms of improved pregnancy outcomes. This is a crucial ethical issue, especially in the light of concerns about increasing pressures and growing responsibilities ascribed to pregnant women, which may, in turn, be reinforced by PRmHealth. A point can be made that it would be ethically askew if PRmHealth does not lead to improved pregnancy outcomes, while at the same time increasing maternal duties to closely monitor fetal development. We conclude that more research is needed to get a view on the benefits and burdens of PRmHealth in order to ethically assess whether the latter are proportionate to the former. If not, there is a case in saying that endorsement of PRmHealth is overdemanding.

许多孕妇使用与怀孕相关的移动健康 (PRmHealth) 应用程序，包括各种怀孕应用程序和可穿戴设备。这些主要是为了支持更健康的胎儿发育。在本文中，我们认为 PRmHealth 日益占据主导地位需要实证知识来肯定其在改善妊娠结果方面的益处。这是一个至关重要的伦理问题，特别是考虑到对孕妇施加的压力和责任越来越大的担忧，而这反过来又可能被 PRmHealth 加强。可以指出的是，如果 PRmHealth 不能改善妊娠结果，同时增加产妇密切监测胎儿发育的责任，这在伦理上是不正确的。我们的结论是，需要更多的研究来了解 PRmHealth 的益处和负担，以便从道德上评估后者是否与前者相称。如果不是，则有理由说对 PRmHealth 的认可要求过高。
