About this app
Answers come only from the WHO, NHS and CDC pages linked on each card, checked on 7 October 2026. Guidance can change, so read the source page. Health Companion has no ads, no sign-in, no AI and collects no health data. The hosting provider sees normal technical request data. Following a source link is covered by that website's privacy policy. NHS pages give UK phone numbers; they do not apply in Nigeria.
