Koi Companion

Koi Companion helps koi keepers keep clear pond, koi, water, health and care records in one place.

Record ponds, koi, water tests, treatments, maintenance, health cases, observations, diary events and reminders. Koi Companion can help review saved records, explain water readings, organise health notes and prepare clearer information for vets, dealers or experienced koi keepers.

The app includes practical pond tools, koi health notes, UK koi events, dealer information and report support. Koi Companion provides practical decision support and record organisation, but it is not a veterinary diagnosis service.

New users can use Basic access, start a 30-day Premium feature trial with a reduced AI allowance, or choose a paid plan. Fair-use AI, report and media storage allowances apply so the service remains reliable and sustainable.

Koi Companion is operated by West Coast Aerial Ltd.
