Two tools with different boundaries
Peptide Tracker draws its boundary around the injection. Inside that boundary it is competent: reconstitution math, vial inventory, and a site rotation history, which is exactly the toolkit a peptide protocol needs. If nothing else in your routine competes for attention, the narrow scope is a feature rather than a limitation.
DoseRoutine draws the boundary around the routine instead. The same injectable tooling is there, but it sits alongside oral supplements, prescriptions, hormone protocols, blood work and food logging, which changes what the app can tell you. A peptide log can confirm you took the dose; a routine log can show that the week you added a second compound is also the week your sleep score moved.
What the wider scope actually buys you
The clearest example is interaction checking. A peptide-only tracker has no reason to know what else you take, so it cannot flag the supplement that competes for absorption with a prescription you take at the same time. DoseRoutine checks across categories and shows the mechanism and the source behind each flag, so you can judge whether it matters to you rather than dismissing an unexplained warning.
The second is the reference layer. Every compound you log is backed by a library entry covering typical dosing, timing, mechanism, monitoring and known interactions, so the decision about how to run something and the record of having run it live in the same place.
The third is longevity. Protocols rarely stay still — a peptide finishes, a hormone dose changes, a supplement gets dropped after labs come back. An app that models cycles, titration and end dates keeps an accurate history through those changes instead of accumulating stale entries.
Who should stay with Peptide Tracker
If peptides are the entire routine, you are happy on mobile, and you do not want lab tracking or nutrition anywhere near your dose log, a focused app will feel lighter every single day. The honest test is what is currently in your notes app or spreadsheet alongside the peptide log. If the answer is nothing, stay. If it is a supplement list, a lab PDF and a reminder about which site you used on Tuesday, that is the gap this comparison is about.
