Alethea vs Regimen: Logger vs “Is It Working?”

*Updated September 8, 2026*

Short answer: Regimen is the strongest pure native logger lane for injectables on iOS/Android — calculators, Health sync, clean logging. Alethea is for the multi-variable “is this working?” job: adherence + labs + multi-brand wearables + AI on your data, on web/PWA.

Side-by-side

Regimen — strongest pure native logger lane

Regimen is a genuinely well-built native tracker: large compound library, reconstitution calculators, injection-site rotation, PK / half-life visualization, Apple Health and Health Connect sync, inventory / beyond-use-date style vial tracking, and a free tier for a single compound. Paid pricing is commonly ~$4.99/mo in public marketing as of Sep 2026 — verify on their site / stores; we hedge with ~ because vendor pages change.

Where it stops for some people: wearable data is primarily Apple Health / Health Connect passthrough rather than direct brand connectors like Oura or WHOOP. If your main question is conversational AI analysis across doses + labs + wearables in one place, that’s a different product shape.

Alethea — outcomes correlation on web/PWA

Alethea logs peptides, GLP-1s, and the rest of your protocol with schedules and adherence, reconstitution math, vial inventory, lab uploads, wearable sync (Apple Health, Fitbit, Withings, Garmin, Oura, WHOOP, and Polar), and AI chat from your numbers.

Honest limits: web / PWA only. Free = no wearable sync. Not HIPAA-covered. No BAA. Not a pharmacy. Not Alethea Medical.

Pricing: Free $0; Premium $9.99/mo or $99.99/yr; Pro $29.99/mo or $299.99/yr; Clinic $1,990/yr (up to 10 patients, 3 staff; month-to-month $199/mo); Founding Member Pro $9.99/mo locked (first 50, web only). Full detail: pricing.

Pick Regimen if…

This is honesty about fit — not an outbound “go buy Regimen” plug from Alethea.

• You track injectables on iOS or Android and want the cleanest native logging experience
• Calculators, site rotation, and Apple Health / Health Connect are enough
• You’re happy with a free one-compound tier or ~$4.99/mo native Pro (per their site)

Pick Alethea if…

• You need doses next to labs and multi-brand wearables, not only Health passthrough
• You want AI that answers from *your* stack over time
• You’re fine installing a PWA / using the full web app
• You’re running more than a simple injectable diary
