The best tracker for peptides, TRT and supplements: how nine apps and a spreadsheet compare

Category 1 — pill reminders

This is the most mature category and the reason adherence apps exist at all: taking a long-term therapy as prescribed is the single biggest lever on whether it works. Reminders, taken/skipped history, adherence percentages and caregiver alerts are all solved here.

The limit is the dose form. These apps assume a countable unit. Ask them to hold 'add 2 mL bacteriostatic water to a 10 mg vial, then draw 12.5 units' and there is nowhere to put it.

Category 2 — nutrition apps

Cronometer in particular is excellent at what it does: food logged down to micronutrient level. If your question is 'am I actually getting enough magnesium from food', this is the right tool.

It is not a dose tracker. Supplements appear as nutrients, not as a scheduled protocol with adherence, and prescriptions and peptides have no home at all.

Category 3 — symptom and mood trackers

Bearable is built to correlate factors with how you feel. That is genuinely useful alongside a protocol, and DoseRoutine's check-ins cover similar ground.

On its own it answers 'how have I felt' but not 'what exactly did I take, in what concentration, from which vial'.

Category 4 — injection logs

Dedicated injection apps get closest on the hardest part: sites, volumes and schedules. Where they stop is the rest of the stack — the oral supplements, the hormones, the interaction checks and the labs that decide whether the protocol continues.

Category 4b — GLP-1-specific trackers

Shotsy is scoped to GLP-1 medications: shots, side effects, weight and estimated medication level between doses, per its own site. It does not describe peptide reconstitution math or TRT/hormone cycle tracking, so a routine that mixes GLP-1s with other compounds still needs a second tool.

Category 4c — reconstitution-only calculators

PepCalc is explicitly a calculator, not a tracker: no signup, no logging, data kept on-device, per its own App Store listing. It solves the mixing math well and stops there — no reminders, no vial record, no history.

Category 6 — health-records hubs

Guava centralizes medical records — labs, visit notes, imaging — and lists medication/supplement use as one of several general daily-logging inputs, per its FAQ. It is built for consolidating records across providers, not for reconstitution math or injection-site rotation.

Category 7 — chronic-condition care platforms

CareClinic organizes prescriptions, supplements and symptoms into condition-specific care plans with standardized clinical assessments, per its features page. Its medication tracker is not described as handling reconstitution math, vial expiry or syringe-unit dosing.

Category 5 — the spreadsheet

A spreadsheet is infinitely flexible, which is why so many people start there. It is also the only option on this list that will never remind you, never warn you that two things interact, never notice a vial is past its beyond-use date, and never plot a lab value against its reference range.

What a single tool has to cover

• Scheduling and adherence for everything, oral and injectable.
• Reconstitution math that ends in a syringe reading.
• Vials: what is open, how much is left, when to discard.
• Injection-site rotation history.
• Labs with reference ranges and trends.
• Interaction checks across the full stack.
• A cited compound library so claims can be traced.
