Your spreadsheet works. Until it doesn't.
You built something that tracks everything — doses, weights, blood results, timing. It's impressive. But it doesn't send reminders, it can't show you a PK curve, and it definitely can't tell you which glute you used last.
We get it. Spreadsheets are flexible, private, and free. You've probably spent hours building yours and it works exactly the way you want. Doseline isn't about replacing your control — it's about getting the same depth with less friction.

Why people switch.
Same data, fraction of the effort.
Every cell in your spreadsheet is a manual entry. Every chart is a manual formula. Every reminder is a separate calendar event. Doseline automates all of it — log a dose in two taps and the PK curve, the history, the site rotation, and the next reminder all update automatically.
Reminders that know your protocol.
Your spreadsheet can't ping you at 7am on pin day. Doseline sends smart reminders based on your actual schedule — and adjusts if you log early or late.
PK curves without the math degree.
If your spreadsheet has half-life calculations, you know how much work that was. Doseline generates pharmacokinetic curves automatically for every medication — absorption, peak, trough, estimated serum concentration — using published PK data.
Your body isn't a text field.
Injection site rotation in a spreadsheet is a text note. In Doseline, it's a visual body map that tracks where you've injected, suggests the next site, and spaces injections to avoid tissue damage.
What you'll gain.

Automatic PK curves (no formulas needed)
Smart reminders based on your schedule
Visual injection site rotation map
One-tap dose logging
Structured bloodwork with dose correlation
Progress photos with timeline
Biometric lock for privacy
Peptide reconstitution calculator
Titration schedule templates
Side effect logging with timestamps

Common questions.
Can I export my data from Doseline back to a spreadsheet?
Yes. Doseline Pro includes PDF and data export. You can always get your data out. We're building CSV export specifically for users who want spreadsheet compatibility.
Is Doseline as flexible as my spreadsheet?
Honestly, no. A spreadsheet can track anything you can think of. Doseline is opinionated — it's built specifically for medication tracking with features like PK curves, site rotation maps, and titration schedules that a spreadsheet can't replicate. You trade some flexibility for a lot of automation and depth.
My spreadsheet is free. How much does Doseline cost?
The free tier is genuinely free — unlimited medications, full history, PK charts, reminders, site rotation, bloodwork, and more. No account required. Pro adds AI features and sync for $4.99/mo, but most spreadsheet users will find the free tier does everything they need.
What if I want to keep using my spreadsheet alongside Doseline?
Go for it. Many users keep their spreadsheet as a backup or for custom analysis, and use Doseline for day-to-day tracking, reminders, and PK visualization. They complement each other well.
