Written by the team behind Peppies. We build one of the apps discussed here, so read us with that bias in mind — we link every competitor so you can check claims yourself, and we say plainly where a competitor is the better fit.

SHOTLOG does exactly what its name says: a fast, focused injection log for iOS. Peppies is a different species — here’s the honest split.

What is SHOTLOG?

Open the app, log the shot, see your history. For users who want frictionless recording and nothing else, that focus is the feature, and SHOTLOG delivers it on iOS today.

What is Peppies, and how is it different?

Peppies treats tracking as three connected questions: What do I actually have? (shelf inventory with lot numbers and third-party COA verification per batch), what does my blood say? (partner-lab panels scheduled into the cycle, reports stored on-device only), and what do my wearables signal? (sleep, HRV, resting heart rate, steps — optional connections to Health Connect, Oura, Whoop, Fitbit).

Notably, Peppies has no dose logging with reminders and no calculator — by design. It is a research-use-only tracking tool that never advises usage. SHOTLOG’s job and Peppies’ job barely overlap.
