Shotsy Alternative: What PepTrac Adds, Point by Point

What is the best Shotsy alternative?

PepTrac, for iPhone. It keeps the core of a GLP-1 routine, which is dose logging with reminders, a level estimate, weight and food, and it adds five things. First, your level is drawn as a range, with a linked source for each half-life. Second, a reconstitution calculator converts vial doses into U-100 or U-40 syringe units. Third, peptides beyond GLP-1 medicines live in the same log. Fourth, a workout tracker has templates, live sets and a rest timer, and the food log adds an AI meal photo scan and barcode. Fifth, an AI assistant reads your own logs and logs a dose only after you confirm. None of these five is described in Shotsy's App Store description or Google Play listing as of October 3, 2026, which is different from saying Shotsy cannot do them.^[1][2] PepTrac records what you enter and never suggests a dose.

How do PepTrac and Shotsy compare?

The two apps share a core: both log GLP-1 doses with reminders, both describe a level estimate, and both track weight and nutrition. PepTrac then adds rows that Shotsy's listings do not describe. Its level is drawn as a curve with a shaded range, a dotted projection and a linked half-life source, while Shotsy's listing says only that it shows estimated levels from clinical data. PepTrac adds a reconstitution and syringe-unit calculator, peptides beyond GLP-1 medicines, workout templates with live sets and a rest timer, and an AI assistant that reads your own logs. Shotsy's listings describe workout logging, Android, a side-effect log and PDF and CSV export, and the table shows each row side by side. We write not listed on purpose, because a silent listing is not proof an app lacks something.

Shotsy is a GLP-1 tracker. Its App Store listing describes logging injections or daily pills with schedules and reminders, estimated medication levels, and weight, calories, protein and water tracking. Listings: App Store and Google Play. Shotsy is a trademark of its owner. PepTrac is not affiliated with Shotsy.

Why would someone look for a Shotsy alternative?

Usually because their routine includes something Shotsy's listings do not describe. We found three gaps in the current listing text. First, no vial or syringe-unit calculator is listed, which matters if you draw a dose from a vial. A 5 mg vial mixed with 2 mL of water is 2.5 mg per mL, so 0.25 mg is 0.1 mL, or 10 units on a U-100 syringe, and the FDA has reported dosing errors with compounded semaglutide.^[4] Second, no peptide catalog beyond GLP-1 medicines is listed, so someone who also records another compound has to keep it elsewhere. Third, no workout templates, rest timer or AI assistant are listed. These are gaps in what the listing says, not claims about what the app can or cannot do. They are the three places where PepTrac was built to do more.

How does each app show medication levels?

Both apps estimate a level from a half-life and your logged doses, and neither measures anything in your blood. PepTrac draws a curve, a shaded range and a dotted projection from your schedule, and cites a half-life source for each compound. The range comes from re-running the model with the half-life and time to peak each changed by 20 percent, so it shows sensitivity, not statistical confidence. Its numbers are relative units, not nanograms per milliliter. The Ozempic label gives semaglutide an elimination half-life of about 1 week, which is why levels build over several weeks of dosing.^[3] For Shotsy we can only repeat what its listing says: estimated medication levels, with charts based on peer-reviewed clinical data.^[1] It does not say whether a range is shown. Whichever you pick, treat the chart as an estimate to discuss with your prescriber, not a lab result.

How do you move your routine from Shotsy to PepTrac?

We have not confirmed that PepTrac can import Shotsy data, so plan on entering a short history by hand. Add your medicine as a compound, choosing semaglutide or tirzepatide, and name it after your product. Enter your current dose and schedule, using steps of dose plus duration if you are on a step-up schedule, so the app can show which step you are on. If you use a vial, enter the vial size and the water you added, and the calculator will show the syringe units for the dose you enter. Check that result against your label. Then log your last few doses with the past-dose option, which gives the level curve some history to draw from, and set reminders. Keep your Shotsy history until you are sure you do not need it, and ask your prescriber before changing any dose or schedule.

1. Add the compoundChoose semaglutide or tirzepatide and name it after your product.
2. Enter the scheduleEnter the dose you take and its steps, if you have them.
3. Add the vialIf you use a vial, enter its size and the water you added.
4. Backfill recent dosesLog your last few doses so the level curve has history.
5. Set remindersPick the day and time for each dose reminder.

What does each app cost?

Both apps are free to download, and both offer paid options, so the useful comparison is price model, not a headline number. PepTrac is free to download, and PepTrac Pro is an optional subscription whose price is shown in the app before you subscribe. We do not list Pro's price here because it can change, and we do not list which features are free and which are Pro. Shotsy's US App Store listing shows in-app purchases, and we have not confirmed which Shotsy features sit behind a paid plan, so check its listing for that.^[1] Open the in-app purchase list on each listing, decide which features you need, and subscribe only to the one you use. Prices and plans change, so these statements are as of October 3, 2026 and worth rechecking before you pay for anything in either app.

What does PepTrac not do that Shotsy does?

PepTrac is an iPhone app. It has no Android version, no Apple Watch app and no dedicated side-effect log. Shotsy's listings describe Android, a side-effect log and daily pill tracking, so if those three decide it for you, Shotsy's own listings are the place to check.^[1][2] On iPhone, PepTrac does something else instead: it syncs steps and calories burned with Apple Health, keeps your doses, sites, weight, food and workouts in one place, and draws your level as a range with a linked half-life source rather than a single line. We make PepTrac, so weigh these limits with the table above. Ask your prescriber about side effects, and use this page to decide whether the five additions in the table matter to your routine. Prices, features and platforms change, so check both listings before you switch.
