Free to download, with no account to create. The phone log has no cap on entries.
Medication records can sync through your own iCloud. Weight and progress photos stay local.

Why Dial
Cycle ring and next reminder on Apple Watch
Opens without a Dial account
Lifetime option, a single purchase
Estimated level between doses (Dial Pro)
Quick logging
Put the details in one dose entry.
Record medication, amount, date, time, and notes. Injections such as Ozempic, Wegovy, Mounjaro and Zepbound include a site. Tablets such as Rybelsus log without one. Dial lists semaglutide, tirzepatide, liraglutide, and dulaglutide with regional brand names. It also logs orforglipron (Foundayo in the U.S.), exenatide, and prescribed compounded semaglutide or tirzepatide from a vial. Add a custom medication if yours is missing.
- Edit an entry when something changes
- Keep injection sites attached to each dose
- Keep weight entries alongside the dose timeline
Apple Watch
Log a dose from your wrist.
The watch app shows a cycle ring counting down to your next dose, and when the next reminder fires. Dial Pro logs from that screen. Set the amount with the Digital Crown, pick an injection site, and confirm. The entry syncs to your iPhone.
- Cycle ring, dose status, and next reminder at a glance (free)
- Log a dose from the wrist with the Digital Crown (Dial Pro)
- Estimated-level and next-dose widgets on your watch face, plus Smart Stack quick logging (Dial Pro)
- On iPhone, Pro enables one-tap logging from Control Center, the Action Button, Siri, or a reminder-day Live Activity. Free actions open the log form.
Dial Pro · Estimated level
Review an estimated level between doses.
Dial plots an estimated level from logged doses and the half-life shown in the app, for supported injectables such as Ozempic, Wegovy, Mounjaro and Zepbound. Tablets such as Rybelsus have no level chart: oral absorption varies too much between people. Review a week, month, or six months of injection history.
An estimate, and we say so.
The chart models how each semaglutide or tirzepatide dose you logged is absorbed and eliminated, using label half-lives. It shows your own patterns between doses. It is an estimate, not a stand-in for a measured blood level. The app explains the method in full.
What Dial does not do
Dial keeps the record. Your prescriber sets the dose.
Dial does not calculate doses, recommend a dose change, or tell you what to do after a missed dose. The estimated level is a one-compartment model estimate of absorption and elimination for each logged dose, not a measurement. The unit converter for compounded vials is arithmetic on the mg and mg/mL you enter and does not suggest an amount. Ask your prescriber or pharmacist about medication decisions.
Everything in the record
Keep the rest of the record together.
PDF report for a clinic visit
Generate a PDF with your dose history, changes in recorded amount, injection sites, weight trend, and side-effect patterns. Dial builds it on your device, and you share it only when you decide to, by AirDrop, email, or print. The same history exports as CSV.
Supply inventory
Track pens, vials, and tablet bottles with expiration dates. Scan a package label to fill in details, then check them before saving.
Your reminders
Create daily, weekly, or every-N-days notifications around the schedule you set. On dose day, a Log dose action sits on the notification, and a Live Activity stays on the Lock Screen until you log, for up to 12 hours.
Import existing entries
Open a compatible medication-tracker export with Dial to import existing entries.
