Log a dose early and Bo goes quiet until the next one. Save custom meals as recipes and log them in one tap. Pause cycles, add past doses, and more.
Bo is the simplest way to track your peptide routine.
Reconstitution math, dose logging, injection-site rotation, and streaks — one place. No spreadsheets. No guessing if you logged today.
NOT MEDICAL ADVICE
Bo is a research and educational tracking tool. It is not a substitute for medical advice, diagnosis, or treatment. Bo does not recommend, prescribe, or endorse any medication. Always consult a qualified healthcare professional before starting, changing, or stopping any protocol.
WHAT BO DOES
• Reconstitution math: vial mg ÷ BAC water = live mg/mL, mg per unit, mL drawn. Research/educational utility, not a dosing recommendation.
• Visual dose log: drag the syringe to your units, log it, see mg and mcg instantly.
• Tablet support: tap-to-pick counts with half-tablet precision.
• Body-map rotation: tap a spot on the figure to remember every site so tissue heals.
• Streaks and freezes: daily flame, freeze tokens earned every 7 days, 8 PM streak-save reminder.
• Daily reminders at the time you pick.
• Clean analytics: dose timeline, total mg, average per dose, full history.
WHO BO IS FOR
Anyone running a structured peptide routine — fat loss, muscle, recovery, longevity, or cognitive support — who wants one place for the math, the schedule, and the site rotation.
YOUR LIBRARY, YOUR NAMES
Bo never suggests or names peptides. You add what you're tracking. Custom vial size, BAC water, and default units per entry. Works for any compound.

So helpful, no more guess work and so much easier to have it in one place.
Bo 1.4 makes your routine smarter and easier to keep honest.
DOSES
- Logged your shot early? Bo now knows. The reminder for that dose goes quiet, the Lock Screen countdown clears, and the home card switches to Taken today with your next shot lined up.
- The next dose Live Activity now appears one hour before your shot and starts reliably even when the app is closed.
- Pause a peptide between cycles: no reminders, no countdowns, while your history and estimated levels stay. Resume anytime.
- Forgot to log? Add a past dose from Analytics, and undo an accidental delete with one tap.
MEALS
- Save your custom meals as recipes: your high protein tiramisu, your exact overnight oats. Re-log them in one tap from the food camera.
- Snap a photo of a dish you saved and Bo recognizes it, offering your recipe instead of a generic guess.
- Ask Bo to fix a meal and the name updates too, so your custom versions stay yours.
- The This Week card now counts meal days, not just doses.
MORE
- The reconstitution calculator now draws your syringe, so you see exactly where to pull the plunger for your dose.
- The weight chart starts at your starting weight, showing the full journey.
- New gender option, and profile edits now sync across the whole app.
- Cleaner popups, sharper alerts, and many small fixes.
