Tinsy
“"Which side did I use last week?"”
Tinsy remembers your last injection spot and suggests the next one, so the answer is on the screen before you ask it.
Zepbound® tracker
Your Zepbound® weeks, written down as they happen.
Tinsy is a tirzepatide diary. Log each Zepbound® shot in seconds, see which spot comes next, and keep a calendar of your treatment you can actually show someone.
Three questions a weekly shot leaves behind
None of them is hard on the day. All of them are hard a few weeks later, which is why they belong in a diary.
Body map, free
“"Is shot day this Tuesday or next?"”
Reminders follow the schedule your prescriber set, and the calendar shows at a glance when you injected and what comes next.
“"I felt off a few days ago, but which day?"”
Log a side effect with how strong it felt and it sits next to your dose, so the pattern is dated rather than guessed.
What the free Zepbound® tracker covers
Logging your treatment is free forever in Tinsy. No trial, no account, no card.
Every shot, logged in seconds
Date and time, medication, the dose your prescriber set and the injection spot. Zepbound® is in the injection list by name, and anything it does not list you can add yourself.
Schedules that are not exactly weekly
Weekly, every N days, split doses and custom dose changes. Dose reminders follow the plan you were given, so the diary fits the schedule you actually keep.
Calendar and history
See at a glance when you injected and what comes next, and scroll back through every dose you logged.
Offline, with no account
Tinsy works without a connection and without a sign-up. See our Privacy Policy. The next dose can sit on your home screen as a widget.
What Tinsy Plus adds to a tirzepatide diary
Tinsy Plus is an optional subscription, billed monthly or yearly, with a 7-day free trial for eligible new subscribers. The dose log above stays free either way.
Weight that behaves like weight
Weight and body measurements as a trend, not a single number, so one heavy morning does not stand in for a whole month. Part of Tinsy Plus.
Side effects with severity
Log what you felt and how strong it was, next to the dose it followed. Over a few weeks your own rhythm becomes visible. Part of Tinsy Plus.
Your estimated level, drawn
Charts and trends, including an estimate of your medication level over time, built from the doses you logged. For self-observation only. Part of Tinsy Plus.
A report to take with you
A doctor report (PDF) with your whole treatment history, plus Apple Health sync, protein, water and fiber goals, and a cycle marker. All in Tinsy Plus.
Zepbound® tracker: common questions
Is Tinsy a Zepbound® tracker app?
Yes. Zepbound® is in the Tinsy injection list. You log each shot with its date, time, dose and spot, Tinsy suggests where the next one goes, and reminders follow your schedule. All of that is free.
Does Tinsy work as a tirzepatide tracker?
Yes. Tinsy is built for semaglutide and tirzepatide treatments. Zepbound® and Mounjaro® are both in its injection list, and if your medication is not there, you can add your own.
Can I use Tinsy as a Zepbound® weight loss tracker?
With Tinsy Plus you can log weight and body measurements and see them as a trend over weeks, next to your doses and side effects. Tinsy does not promise or predict results. It shows what you logged, so you can talk it through with your prescriber.
Does it handle a schedule that is not exactly weekly?
Yes. Weekly, every N days, split doses and custom dose changes are all supported, and dose reminders follow the plan your prescriber set.
Will Tinsy tell me when to change my dose?
No. Tinsy never calculates or recommends doses. Dose changes are your prescriber's decision; Tinsy records the plan you were given and shows what happened on it. It is a wellness diary, not a medical device.
Is Tinsy affiliated with the maker of Zepbound®?
No. Tinsy is an independent wellness diary. Zepbound® is a registered trademark of its owner and is named here only to say which treatments the diary supports.
