A line the company declared to usedby itself, or that it lists as a sub-processor on its own legal page, is marked declared. A signal is never a case study or a vendor listing. Strongest proof first. "Last check" is the later of the line's re-verification and its latest capture. | Tool | Company | Proof | Source | Last check | |---|---|---|---|---| | Retool | [University of Texas Medical Branch](https://www.usedby.ai/companies/university-of-texas-medical-branch.md) | Confirmed | [retool.com](https://retool.com/customers/utmb), captured 2026-10-02 | 2026-10-24 | | Retool | [Philips](https://www.usedby.ai/companies/philips.md) | Observed | [retool.com](https://retool.com/customers), captured 2026-10-24 | 2026-10-24 | | Retool | [GoodRx](https://www.usedby.ai/companies/goodrx.md) | Observed | [retool.com](https://retool.com/customers), captured 2026-10-24 | 2026-10-24 | | Retool | [Hims](https://www.usedby.ai/companies/hims.md) | Observed | [retool.com](https://retool.com/customers), captured 2026-10-24 | 2026-10-24 | | Retool | [Levels Health](https://www.usedby.ai/companies/levels-health.md) | Observed | [retool.com](https://retool.com/customers), captured 2026-10-24 | 2026-10-24 | | Retool | [McKesson](https://www.usedby.ai/companies/mckesson.md) | Observed | [retool.com](https://retool.com/customers), captured 2026-10-24 | 2026-10-24 | | Retool | [Ōura](https://www.usedby.ai/companies/oura-ouraring-com.md) | Observed | [retool.com](https://retool.com/customers), captured 2026-10-24 | 2026-10-24 | | Retool | [Quest Diagnostics](https://www.usedby.ai/companies/quest-diagnostics.md) | Observed | [retool.com](https://retool.com/customers), captured 2026-10-24 | 2026-10-24 | | Retool | [Zocdoc](https://www.usedby.ai/companies/zocdoc.md) | Observed | [retool.com](https://retool.com/customers), captured 2026-10-24 | 2026-10-24 | | Bubble | [Understanding Zoe](https://www.usedby.ai/companies/understanding-zoe.md) | Observed | [bubble.io](https://bubble.io/customers), captured 2026-10-24 | 2026-10-24 | | Bubble | [EZRA](https://www.usedby.ai/companies/ezra.md) | Observed | [bubble.io](https://bubble.io/customers), captured 2026-10-12 | 2026-10-12 | | Bubble | [Hive Health](https://www.usedby.ai/companies/hive-health.md) | Observed | [bubble.io](https://bubble.io/), captured 2026-10-22 | 2026-10-22 | | Replit | [Norstella](https://www.usedby.ai/companies/norstella.md) | Confirmed | [replit.com](https://replit.com/customers/norstella), captured 2026-10-07 | 2026-10-07 | | Replit | [Northern Health](https://www.usedby.ai/companies/northern-health.md) | Confirmed | [replit.com](https://replit.com/customers/northern-health), captured 2026-10-07 | 2026-10-07 | | Bolt.new | [NetDoctor](https://www.usedby.ai/companies/netdoctor.md) | Observed | [bolt.new](https://bolt.new/blog/category/customer-stories), captured 2026-10-19 | 2026-10-19 | | Lovable | [HCA Healthcare](https://www.usedby.ai/companies/hca-healthcare.md) | Observed | [lovable.dev](https://lovable.dev/customers), captured 2026-10-16 | 2026-10-16 | ## Method Public customer lines of active App builders & no-code tools at companies classified in Healthcare.
