Why SteroidPlotter ranks for this query
SteroidPlotter owns the brand query because the whole page is the tool: a web-based planner for plotting compounds by dose, timing, and half-life. Its page also includes examples, protocol categories, and a prominent disclaimer that its pharmacokinetic model is simplified.
For the alternative query, the searcher is usually comparing jobs: graph a cycle once, or maintain a day-to-day record. Halflife should win only when the user needs the second job.
SteroidPlotter vs Halflife
| Need | SteroidPlotter | Halflife |
|---|---|---|
| Quick browser graph | Strong fit for web plotting | Better when the graph belongs with the log |
| Injection event history | Not the primary workflow | Date, time, amount, unit, site, and status stay in the record |
| Mobile reminders | Not established from the public page | Built around schedules and recorded completion states |
| Vial and supply context | Not the primary workflow | Vial inventory and runway context can stay beside the protocol |
| Model boundary | Public disclaimer says the model is simplified | Curves are labeled estimates, not measured concentrations |
| Best fit | People who want a fast public web plotter | iPhone users who want a private protocol record over time |

What not to infer from either tool
A plotted curve is not a lab result. It cannot prove serum testosterone, estradiol, hematocrit, symptom cause, or clinical response. It also cannot make a prescribed schedule safer. The defensible use is record-keeping and model explanation.
Frequently asked questions
What is a SteroidPlotter alternative for phone tracking?
Halflife is a SteroidPlotter alternative for iPhone users who want protocol logs, reminders, injection-site history, vial inventory, and estimated remaining-level curves in one place.
Should I use SteroidPlotter or Halflife?
Use SteroidPlotter when a browser plot is the main task. Use Halflife when a continuing mobile record is the main task.
Can either tool determine my dose?
No. Dose decisions belong to current prescribing information and qualified clinical care, not a consumer plot or log.
