Common questions
Is this medical advice?
No. The app is for tracking and education only. It does not diagnose, treat, or replace care from a clinician. Medication decisions, including anything about a GLP-1 dose or a change in treatment, belong to your prescriber or care team. For more detail, see the medical disclaimer.
Does the app tell me my dose?
No. The taper timeline only records the dose steps you type in. It does not calculate, validate, or suggest doses, and it does not tell you what to do with your medication. Any questions about semaglutide, tirzepatide, or other GLP-1 medication decisions belong to your prescriber.
Is the app available?
Not yet. Ballast is planned, and the app is not released at this time. The site is a reference and calculator preview for adults who are tapering, have stopped, or are maintaining after a GLP-1 medication.
Where does my data go?
The app is designed to store data on your device. There is no account, and you will be able to export and delete everything. To read more about how data is handled, visit the privacy policy.
What does it cost?
The app will have a free tier plus an optional Pro subscription. The price will be shown in the App Store purchase sheet once the app is live. More details are listed on the pricing page.
Where do protein and fiber numbers come from?
The protein targets are based on body weight and on a joint advisory from ACLM, ASN, OMA, and TOS. That advisory notes an adult RDA of 0.8 g of protein per kg of body weight per day, and says suggested targets of 1.2 to 1.6 g/kg per day have been discussed during active weight loss. It also says the right way to calculate protein is unclear, and that protein alone is not enough without strength training. If you have kidney disease or your clinician has set a limit, follow their guidance.
For fiber, the app does not give a gram target. It only points you toward more fiber-rich foods such as vegetables, beans, fruit, and whole grains, and reminds you to increase fiber slowly and drink water.
Will it keep my weight off?
No app can promise that. Some people want tracking tools because weight change can happen after GLP-1 treatment changes. In one trial, adults who had completed 36 weeks of tirzepatide and then switched to placebo gained 14.0% of body weight from week 36 to week 88, while those who continued tirzepatide lost a further 5.5%. That study does not tell any one person what will happen, and it does not replace medical care.
The app may help you notice trends in weight, appetite, protein, fiber, and strength work, but it cannot prevent regain or guarantee an outcome. If eating feels hard, talk with a clinician.

Key facts
- In SURMOUNT-4 (JAMA 2024), from week 36 to week 88 people switched to placebo gained 14.0% of body weight, while those who continued tirzepatide lost a further 5.5%. Source
- A joint nutrition advisory (2025) says 1.2 to 1.6 g of protein per kg per day has been suggested during weight loss; the adult RDA is 0.8 g/kg. These are suggested targets, not requirements. Source
- Fiber guidance generally encourages more vegetables, beans, fruit and whole grains; add fiber slowly and drink water. Source
