Trulicity Tracker for iPhone

Why track Trulicity at all

Trulicity is dulaglutide, a once-weekly GLP-1 with a half-life of about five days and a median time to peak near 48 hours. Steady state arrives somewhere between the second and fourth dose, so the first month on any strength is a moving target rather than a settled one. A record of which week you were on which dose is what turns that month into something you can actually read afterwards.

Dulaglutide is approved for glycemic control in type 2 diabetes and for lowering cardiovascular risk. It is not approved for weight management, which makes the numbers worth tracking slightly different from the weight-first compounds: HbA1c between clinic visits, blood pressure, resting heart rate and side effects during the weeks after a strength change. OptiPin plots bloodwork results on the same timeline as the doses, so a lab value is read against the dose you were on when it was drawn rather than against the date alone.

The pen itself removes one job and leaves another. It is a fixed single-dose device, so there is nothing to dial and no clicks to count. What is easy to lose is the date of a strength change. That is exactly the thing you want in front of you when a side effect shows up three weeks later.

What the OptiPin Trulicity tracker does

OptiPin tracks Trulicity alongside Ozempic, Mounjaro and Victoza or Saxenda on one timeline, which matters most during a switch: dulaglutide's five-day half-life means it is still clearing for two to three weeks after the last pen. That overlap is easier to see drawn than to hold in your head.

Free dose tools for Trulicity

Calculators that pair with tracking, no app needed to use them:

• Half-life visualizer – see how weekly 5 day half-life doses stack toward steady state, then how long the last one takes to clear.
• GLP-1 titration schedule – lay your prescriber's steps out week by week so you can see where you are in the ramp.

The pen click chart does not apply to Trulicity: its pen delivers one fixed dose with no selector, so there is nothing to convert. Reconstitution math does not apply either, because the pen arrives pre-filled.

One app for everything you're on

Most people on dulaglutide are on other things too, often metformin, a statin or blood-pressure medication. All of it belongs on one timeline with one set of insights instead of fragmented across a notes file and your memory. That is the difference between logging a drug and seeing your protocol.
