Weight management software

Efficient management of healthy weight initiatives and programmes

Better tools. Healthier outcomes.

We understand the challenges your team faces: inflexible data capture, slow communications, and the pressure to deliver more with limited resources.

Every client deserves easy access to support, whether they’re joining a 12-week programme, following a bespoke plan, or attending sessions in the community or online. And your team deserves software that makes it simple to manage every step of their journey.

That’s where theseus comes in. 

Our weight management software allows you to easily assess and manage clients, record progress, and track outcomes with confidence. Capture weight loss assessments, targets, timescales, and contact sessions—all tailored to your service. Automated reporting supports Adult Tier 2 Behavioural Weight Management Services submissions to the Office of Health Improvement and Disparities (OHID), so compliance is hassle-free.
