A Trulicity tracker that watches the fridge clock too

Steadyway is an iPhone app for people on Trulicity: the weekly injection, the 0.75 to 4.5 mg ladder, side effects, and a 14-day out-of-fridge window that is easy to overrun.

Yes — Steadyway. It tracks the weekly injection, the 0.75 to 4.5 mg ladder, side effects and supply, and it is unusually careful about the one thing Trulicity punishes: the fortnight a pen survives outside the fridge.

Doses 0.75, 1.5, 3 and 4.5 mg
Taken as Weekly injection, dulaglutide
Licensed for Type 2 diabetes (UK, EU, US)
Out of the fridge 14 days once in use
Missed a dose Take it if there are at least three days until your next dose. Fewer than three, skip it and take the next one as planned.

Fourteen days is the shortest window of the lot

Half of Mounjaro's thirty, a third of Wegovy's forty-two. That is the number people get wrong, because it is the one nobody expects to be different — a pen packed for a holiday on the assumptions that work for somebody else's Wegovy will quietly expire while looking completely normal.

The app counts from the day you say the pen came out and nudges you before the window closes.

Where the last one went

Six rotation sites, each showing when it last came round, so the picker suggests the one that has rested longest. A dose taken two days late is logged as late rather than quietly as missed, which matters when the record is going to a diabetes review.

You do not have to use the weight half

Most of Steadyway is built for people losing weight, and on Trulicity most people are not. Nothing in the app requires a goal weight or a target — the dose schedule, the site rotation, the side-effect log and the supply count all stand on their own, and the trend view works fine as a record of what happened rather than a march toward a number.

Something to take to your review

A two-page PDF: trend, doses, side effects, notes. It exists so the appointment starts from a record rather than from what you can remember about the last three months.

From Steadyway

Setup is your current dose and the day you inject — the weight is optional and can stay that way.

Everything is written to the phone and read back from it, so it opens instantly and works with no signal.

Common questions

Why does the fridge matter more on Trulicity?
Because its window is the shortest of any of them — 14 days at up to 30 °C, half of Mounjaro's and a third of Wegovy's. A pen taken travelling on the same assumptions as a friend's Wegovy will expire while it still looks perfectly fine.
Does it know the Trulicity doses?
Yes — 0.75, 1.5, 3 and 4.5 mg, with the pen you used recorded against each injection so the titration chart shows how long you spent on each step.
I take it for type 2 diabetes rather than weight. Is the app still useful?
The dose schedule, the site rotation, the side-effect log and the supply count all work the same way. The weight side is the part built for weight loss, and you can simply not use it — nothing in the app requires a goal weight.
Can I export something for my appointment?
A two-page PDF: trend, doses, side effects and notes. It exists so you are not scrolling a phone at a desk while somebody waits.
