Regimio vs OptiPin.
OptiPin is one of the fastest TRT injection loggers, with an excellent tap-to-log body diagram. Regimio keeps that fast logging idea and adds the analytical layer around it: reconstitution math, a cross-stack timeline, labs, and peptides and GLP-1 in the same app. Here is an honest comparison.
- Best-in-class tap-to-log injection body diagram
- Local-first storage, which we respect and build on
- Free with in-app purchases, easy to start
- The analytical layer
OptiPin is a focused injection logger. Regimio adds the layer on top: reconstitution math, vial-life countdowns, a cross-stack timeline, labs, and pattern flags, all derived from what you log.
- More than TRT
OptiPin centers on TRT injections. Regimio runs TRT, peptides, GLP-1, supplements, and labs together, with reconstitution and site rotation per compound.
- 5-state site rotation
Regimio's body map color-codes every site with five recovery states and tracks sub-Q and IM separately per compound, not just used vs unused.
- Reconstitution built in
Regimio computes draw volume and U-100 units inside the logger, so the calculator is not a separate step.
Side by side
Regimio vs OptiPin, at a glance.
| OptiPin | Regimio | |
|---|---|---|
| Primary focus | TRT injections | TRT, peptides, GLP-1, supplements, labs |
| Reconstitution math | Separate / manual | Built into the logger |
| Data storage | Local-first | On-device by default |
| Injection site map | Tap-to-log diagram | 5-state map, per-route per-compound |
| Analytics layer | Minimal | Timeline, vial life, pattern flags |
| Price | Free + IAP | Free tier + optional Pro |
OptiPin is excellent if you want the fastest possible TRT injection logger and nothing more. Regimio keeps that speed and adds the analytical layer plus peptides, GLP-1, and labs, while staying on-device. If your stack is just TRT injections, OptiPin is great; if it is broader, Regimio fits.
FAQ
Regimio vs OptiPin, answered.
Is Regimio a good OptiPin alternative?
Yes, if you want more than a TRT injection logger: reconstitution math, a cross-stack timeline, labs, and peptide or GLP-1 tracking in the same app. OptiPin remains excellent for fast, focused TRT injection logging.
Does Regimio keep data local like OptiPin?
Yes. Both are local-first. Regimio stores your data on your device by default with no account required and a one-tap wipe.
What does Regimio add over OptiPin?
Reconstitution math in the logger, a 5-state site-rotation map tracked per compound and route, vial-life countdowns, a cross-stack timeline, lab tracking, and support for peptides and GLP-1 alongside TRT.
