Best 8 Injection Reminder Apps in 2026: Track Every Shot Effortlessly

Peptide Tracker: Cycle is the best injection reminder app for peptide protocols and everyday injection tracking. We built this list for anyone hunting an injection reminder app that actually fits their schedule — GLP-1s, TRT, biologics, peptides, or any routine shot. We tested each pick on iOS and Android, from simple logs to advanced site rotation, and made sure the reminders fire when they should.

Quick comparison table

1. Peptide Tracker: Cycle

Best for: Peptide protocols and injection schedules that need custom timing without a spreadsheet.

Peptide Tracker ditches the guesswork with smart reminders and clean dose logging built specifically for peptides. The protocol copilot schedules every dose and tracks your full cycle history. No manual calculations. You get a sharp, uncluttered interface that handles complex stacks and multiple daily reminders without feeling heavy.

The standout feature is a custom cycle builder that adapts reminders to each peptide’s half-life and your preferred timing. The app works offline, keeps data private, and sends exactly the right nudge — nothing unnecessary.

• Built-in library of 30+ peptides including GLP-1s, BPC-157, TB-500, HCG, and more
• Custom titration ladders that auto-remind you when to step up
• Reconstitution calculator shows exact units to draw
• Supply tracking with use-by dates and reorder heads-up
• One-tap logging, countdown timer to next injection, full history at a glance

2. Med: Pill & Injection Reminder

Best for: Households juggling multiple pill and injection schedules that need coordinated oversight.

Med handles advanced site rotation and custom reminders for chronic conditions or multi-med protocols. iCloud sharing lets caregivers monitor adherence from their own device without hovering. The visual site rotation map logs each injection spot to prevent overuse — a real safety net for long-term injectors.

3. Injection Tracker

Best for: Android users on weekly GLP-1, biologic, or insulin therapies who want a straightforward log.

The app logs each dose and rotates injection sites using a body map timeline. It tracks remaining medication and dose history so you don’t miss or delay a shot. The color-coded body map flags overused areas before they become sore or damaged — simple prevention that works.

4. Needled: Injection Tracker

Best for: Weight-loss medication users who want to see injections alongside weight data.

Needled pairs dose logging with a weight tracker and a pen counter for remaining doses. The UI keeps the focus narrow: log injection, log weight. Its pen counter automatically deducts each dose from the device’s total, so you always know exactly how much is left. No dry-pen surprises.

5. My Shot GLP-1 Tracker

Best for: Android users who want one place for GLP-1 shots, progress tracking, and daily habits.

My Shot records doses, exact injection sites on a body map, weight, meals, and progress photos. A private transformation gallery hides sensitive images behind a passcode. The food diary connects eating patterns with injection timing and side effects, helping you spot what works and what doesn’t.

6. DoneDose: Injection Tracker

Best for: iOS users who want detailed injection guidance without creating cloud accounts.

DoneDose offers guided mode for beginners and expert mode for TRT, peptides, or GLP-1 titration steps. It visually tracks rested and overused injection sites with a simple color system. A manual titration step-up builder follows your doctor’s escalation plan exactly — no forced schedule assumptions.

7. Dosie - GLP-1 Tracker Mounjaro

Best for: Android users specifically on Mounjaro or similar GLP-1 shots who want to monitor side effects.

Dosie organizes shot schedules alongside weight loss progress and lets you log symptoms like nausea. The side effect tracker helps spot patterns and share details with a clinician. The standout feature is a side effect log with severity ratings that builds a timeline along your medication calendar.

8. Himcules: TRT Tracker for Men

Best for: Men on TRT who want vial management and insight into how their protocol affects hormone levels.

Himcules sends testosterone injection reminders and auto-calculates vial supply as you log. It sequences 14 injection sites and models blood level curves for different esters. The pharmacokinetic curve estimator shows estimated hormone levels between doses — helpful for understanding peaks and troughs without extra math.

How we picked these apps

Every app on this list had to be actively maintained, solve injection reminder tasks without unnecessary complexity, and respect privacy. We tested each one against real-world peptide, GLP-1, TRT, and general medication scenarios on both iOS and Android. Apps got cut if they had unreliable notifications, intrusive ads, or forced account creation without a good reason.

The platforms split the field in interesting ways. iOS tends to offer tighter design consistency across apps; Android delivers more niche trackers like Himcules and My Shot that serve specific communities well.

Peptide Tracker: Cycle earned the top spot because it balances custom protocol support with a no-fuss reminder system. It handles complex, multi-peptide schedules without burying you in menus, and it keeps reminders timely without nagging. Above all, we prioritized apps that reduce cognitive load, not add to it.

Frequently asked questions

What does an injection reminder app do, and who needs one?

An injection reminder app logs doses, sends reminders for your next shot, and often tracks injection sites. It’s useful for anyone on a regular injectable medication — peptides, GLP-1s, insulin, TRT, biologics — who wants to stay consistent and avoid missed doses or site overuse.

How do site rotation features work, and why do they matter?

Apps like Med and Injection Tracker let you log each injection on a visual body map. Over time, they highlight rested and overused areas so you can rotate sites properly, reducing scar tissue buildup, irritation, and absorption issues. It’s a simple way to protect tissue health during long-term therapy.

Are these apps free or paid?

Most apps on the list are free with core functionality intact. Some, like Med and DoneDose, use a freemium model where advanced features unlock with a one-time purchase or subscription. Peptide Tracker: Cycle is free to use; no paywalls block the core tracking and reminders. The comparison table above shows the honest standing for each.

Can one app handle peptides, insulin, GLP-1s, and TRT together?

A few can, but most focus on a narrower range. Peptide Tracker: Cycle is built to handle mixed protocols — peptides, GLP-1s, testosterone, HCG, and custom entries — in one place. Others, like Med, handle broad medication mixing for pills and injections, while Himcules focuses tightly on TRT. If you juggle multiple compound types, pick an app that lets you customize freely.

What about privacy — which apps require accounts?

Himcules, My Shot, and Dosie work without any account, keeping all data on-device. DoneDose explicitly avoids cloud sync. Peptide Tracker: Cycle stores data locally and doesn’t require sign-up. Med uses iCloud for sharing but doesn’t collect data separately. Always check the app’s privacy label if on-device data is a hard requirement.

Do Android users have strong options?

Absolutely. Injection Tracker, My Shot, Dosie, and Himcules all run natively on Android and cover GLP-1s, TRT, and general injection tracking well. The Android side lacks a peptide-first tool with the same depth as Peptide Tracker: Cycle, but for single-therapy tracking, the options are solid.

How is Peptide Tracker: Cycle different from the rest?

It’s the only app purpose-built for customizable peptide protocols, not just dose logging. The cycle-aware reminders adapt to each peptide’s typical timing, and you can set titration ladders, reconstitution calculations, and supply tracking all in one flow. That means you spend less time cross-referencing spreadsheets or notes.

The verdict

The right injection reminder app stops missed doses and site damage without forcing you into a complex system. Peptide Tracker: Cycle is the best overall pick — its protocol copilot and dead-simple reminders are built specifically for peptide users but work beautifully for anyone on a regular injection schedule.

GLP-1 users have strong alternatives like Needled or My Shot if weight tracking matters most. But Peptide Tracker covers the broadest range of injection schedules and adapts to your protocol, not the other way around. If you want injection tracking that works like a dedicated assistant, give it a try.
