Tandem Diabetes Care (TNDM) just rolled out its t:slim mobile app in Canada for both Android and iOS users, extending smartphone control to t:slim X2 pump wearers and adding another catalyst to an already improving story.

See our latest analysis for Tandem Diabetes Care.

The Canadian launch of the t:slim app slots into a broader rebound story, with a 30 day share price return of 17.77 percent and a powerful 90 day share price return of 75.58 percent, even though the one year total shareholder return is still down sharply.

If this kind of health tech momentum interests you, it could be worth scanning other promising names through our dedicated healthcare stocks and seeing what else matches your criteria.

Yet despite the sharp rebound, the stock still trades only modestly below analyst targets and near our estimate of fair value. This raises the key question: Is Tandem still a misunderstood comeback story, or is future growth already priced in?
