02 · Targets & progress

The numbers you're chasing.

Week-aware macros · today, in contextCORE
Set daily targets once. The app keeps rolling 7-day totals so a heavy Wednesday becomes a lighter Thursday. Every macro row tells you exactly how much is left for today — your targets don't rewrite themselves, but your plan for the day does.

Half-life math, automated.

Library + custom compoundsCORE
Common GLP-1s preloaded. Adding your own takes four fields — name, half-life, interval, and kinetics shape. The curve draws itself.

Kinetics shapes · bolus / sub-Q / depotCORE
Not every compound absorbs the same way. Pick the profile that matches how yours hits — the curve adjusts. Sub-Q is the default for self-injected peptides; depot for long-acting oil-based weeklies; bolus for anything that peaks immediately.
Bolus
Instant peak, then exponential decay. IV-like or anything that hits peak almost immediately.
Sub-QDEFAULT
Rises over a few hours, then decays. Default for self-injected peptides and GLP-1s.
Depot
Slow release — lower peak, much longer tail. Long-acting weeklies and oil-based formulations.
Stacked doses · modeled correctlyCORE
Run two compounds at once and the curves add up the way real pharmacokinetics do — not a toy bar chart. Each dose decays at its own half-life.

Push reminders · interval + one send-timeCORE
Each compound has its own dose interval and a single reminder time. The next dose day is computed from your last log plus the interval — the push fires at your chosen hour on dose days only. A separate daily tracking reminder nudges you in the evening if you haven't logged anything yet.

Smart daily reminder · skips if you already loggedCORE
The evening tracking reminder checks your log first. If the day already has any entry — a weigh-in, a dose, a meal — the push doesn't fire. No "did I do that already?" lookups at bedtime.

06 · AI

Agentic. Not a chatbot.

Reads your data · uses tools · actsPREMIUM
Ask it anything. It has tools for searching foods, creating custom items, logging entries, pulling any stretch of your own data, and searching the web. What it can't look up from your log, it finds online — then writes the log for you.
