8fit

8fit is a consumer health and fitness application offering personalized home workout programs (HIIT, boxing, Pilates, yoga, and meditation), custom healthy meal and nutrition plans, and holistic wellness guidance built around sustainable habit-building rather than quick fixes. Founded in Berlin and surfaced in the API Evangelist network as a portfolio company of Creandum, 8fit reached more than 40 million downloads before being acquired by Withings (a Gilde Healthcare portfolio company) in February 2022. Withings announced the discontinuation of the standalone 8fit app effective June 26, 2026, folding its nutrition and activity content into the Withings app and Withings+ service. 8fit is a mobile/web consumer app and does not publish a public developer API; this profile captures its public web, security, and identity surface.
