Get Claritide

Checked on 10 October 2026

A Shotsy alternative for GLP-1 vial users.

We make Claritide. It is a Shotsy alternative built for the details a vial adds: the syringe calculation, remaining supply and blends, alongside your shot log and progress. Keep them together on your iPhone.

Why Claritide fits vial users.

The mark to draw to
Enter the vial’s strength, or the powder and the bac water you mixed, and your dose. Claritide shows the mark on a U-100 syringe. Each vial keeps its own strength.
What is left
Every dose you log draws the vial down. You get a warning about 10 days before a vial runs out, and when a mixed vial reaches its discard date.
Blends
A blend is one vial, with each compound’s amount worked out from its certificate of analysis.
Pens too
A pen shows the dose to dial, with no math.

Your record goes beyond the vial: reminders, site rotation, side effects, weight, photos that stay on your iPhone, an estimated levels chart and a one-page report for your doctor. It is a practical way to bring your injection routine and progress together.

Start with your vial’s strength and the schedule you already follow. Try Claritide to see your draw mark, log your shots and keep track of what remains.

What Shotsy includes.

  • Its core tracking is free, with no time limit: shots and doses, reminders, site rotation, side effects and weight charts.
  • Shotsy+ adds an estimated level chart and Apple Health sync.
  • It handles brand pens, compounded doses you type in, more than one GLP-1 at a time, and GLP-1 pills on iPhone.
  • It makes a PDF of your doses, side effects and weight to share with your doctor.
  • It runs on iPhone and Android, in 17 languages.

On the App Store it has a 4.8 rating from 33.3K ratings (10 October 2026).

“I was simply trying to remember what my last injection site was for close to a year before I found this app.”

App Store review of Shotsy, 13 September 2026

It suits people on brand pens who want a free, simple log, and people who take a GLP-1 pill or more than one GLP-1.

What a vial adds to the job.

A pen is labelled in mg and counts its own doses. A vial hands three jobs back to you.

Units from the vial’s strength
The number on the syringe depends on how strong the vial is. A new vial can have a different strength, and then the same dose takes a different number of units.
What is left
How many shots the vial still holds, when it runs out, and when an open vial has to be thrown away.
Blends
Some peptide vials hold two or three compounds, each with its own amount in every draw.

“didn’t realize it’s on me to calculate the correct dosage for myself with multi use vials”

r/compoundedtirzepatide, 17 September 2026

Shotsy lets you enter the exact dose your prescription calls for, and it says it “tracks doses and schedules rather than vial inventory”. Its listing and website do not say it works out units from a vial’s strength.

Three apps, side by side.

Shotsy, Glapp and Claritide, as of 10 October 2026. Claritide is shaded.

Other options vial users name.

Glapp

Glapp tracks vials for free: each vial’s strength, what is left and the date on its label, on iPhone, Android and the web. Its vial guide links separate dose calculators; the home page describes them as built-in. Glapp Max adds reports and predictions.

“I love that Glapp has a supply feature that tells you how many mgs are left in your open vial after you log your injection.”

Fat Scientist

Fat Scientist is a free website of GLP-1 vial calculators, including one for moving between vials of different strengths. It can be useful when all you need is a calculation.

Peptide Tracker

Peptide Tracker from Flat Six Labs is free, with a reconstitution calculator, vial inventory and blend vials, on iPhone, Android and the web.

Questions, answered.

Is Shotsy free?

Shotsy says its core tracking is free with no time limit: shots, reminders, site rotation, side effects and weight. Shotsy+ adds the estimated level chart and Apple Health sync. Checked on shotsyapp.com on 10 October 2026.

Does Shotsy track vials?

Shotsy says it tracks doses and schedules rather than vial inventory, so a pen and a vial are logged the same way. It does not say it works out units from a vial’s strength.

Can Claritide work out the units from my vial?

Yes. Enter the vial’s strength, or how you mixed it, and your dose, and Claritide shows the mark on a U-100 syringe. It does not show a mark for doses in IU.

Can I bring my Shotsy history into Claritide?

Not directly. Claritide imports only its own backup file, so your log starts fresh. Shotsy can export your history as a PDF or a spreadsheet file for your records.

Is Claritide free?

No. It is $59.99 a year or $14.99 a month, and eligible subscribers get the first 7 days free. The calculator on this site is free.

Where the facts come from.

Claritide’s facts come from the app itself. Its prices are on the pricing page, and how it handles your data is in the privacy policy.
