Switching from Vially?
Vially covers a lot of ground on iOS. Doseline covers more ground on every platform — with PK modeling that shows you what's happening between doses.
Vially does a lot right: 100+ compounds, multi-medication tracking, side effect correlation, and a solid free tier. If you're on iOS and don't need PK curves or HRT support, it's a capable app.

Why people switch.
Your data between doses matters.
Vially tracks when you inject and what you inject. Doseline shows what happens next — the absorption curve, the peak, the trough, the estimated serum concentration between doses. That's the difference between logging and understanding.
Android isn't an afterthought.
Vially is iOS-only. If you switch phones, share a protocol with a partner on Android, or just prefer Android — you're out of luck. Doseline runs natively on both platforms with full feature parity.
HRT community, first-class.
Vially serves GLP-1, TRT, and peptide users but doesn't explicitly support transgender HRT protocols. Doseline was built for all four communities from day one — no gendered defaults, no afterthoughts.
Design with intention.
Doseline's interface was designed with specific principles: restraint, asymmetry, and data as the visual hero. Every screen earns its elements.
What you'll gain.
Switching from Vially to Doseline gets you:
Pharmacokinetic curves for every medication
Android app with full feature parity
Web dashboard for desktop access (Pro)
HRT community support
Health Connect integration on Android
Customizable dashboard layout
Medication level estimation between doses
Calendar export (iCal)

Common questions.
Can I import my data from Vially?
We're building import tools for common formats. Vially uses iCloud backup — we'll support importing from exported data. You can also run both apps during the transition.
Does Doseline have the same side effect correlation feature?
Yes. Doseline logs side effects and correlates them with your dosing schedule. With PK modeling on top, you can also see whether side effects align with peak or trough serum levels — something Vially can't show.
I'm on iOS and happy with Vially. Why switch?
If Vially works for you, no reason to switch. Doseline is for people who want PK modeling (understanding what happens between doses), HRT support, or the option to access their data from Android or the web in the future.
Is Doseline's free tier as generous as Vially's?
Yes. Both offer core tracking for free. Doseline's free tier includes unlimited medications, full injection history, PK charts, reminders, site rotation, weight tracking, body measurements, side effects, progress photos, bloodwork logging, and more.
