Two studies demonstrate that, compared with existing paper-based job aids, mobile phone-based mSakhi is a more user-friendly and effective accredited social health activist (ASHA) job aid for a range of activities,including self-learning, counselling, and newborn assessment. Although the two studies' limited sample size and short duration do not permit measurement of mSakhi's effect on community-level health outcomes, these promising data suggest that mobile applications may be an important tool to support ASHAs in improving maternal and newborn health outcomes.
