Five trackers, compared honestly.
Protocol Her, Shotsy, Glapp, MeAgain, and DoneDose all help you log injections, and they are built for different people. Here is what each app supports today, feature by feature, with the gaps on our side left in the table.

Each app, fairly summed up.
Protocol Her is the only tracker in this comparison built specifically for women: a 35-compound peptide and GLP-1 library, cycle-aware logging, and health data that never leaves your iPhone.
Shotsy is a mature, well-loved GLP-1 shot tracker with estimated medication level charts built on peer-reviewed data, a visual injection site map, and PDF reports for your care team.
Glapp is a community-driven GLP-1 tracker that runs on iPhone, Android, and the web, with medication level curves and a cloud account that moves with you between devices.
MeAgain wraps GLP-1 tracking in an all-in-one lifestyle app, adding AI food logging, side effect tracking with severity, and a companion chat to the basics.
DoneDose is a young injection tracker with unusually broad coverage, spanning GLP-1s, TRT, and peptides, with on-device storage and estimated serum level charts.
Pick by what you actually track.
If you want medication level graphs
Shotsy, Glapp, MeAgain, and DoneDose all draw estimated level curves between doses. Protocol Her does not have that feature today, and we would rather tell you that here than have you find out after downloading.
If you track more than GLP-1s
Shotsy, Glapp, and MeAgain are GLP-1 apps. DoneDose accepts peptides generically alongside TRT and insulin. Protocol Her ships a curated library of 35 named compounds with regulatory status shown on every one.
If privacy decides it
Protocol Her and DoneDose keep health data on the device with no account. Shotsy stores data on device with private iCloud sync on iOS. Glapp and MeAgain sync your history to a cloud account, which is what makes cross-device access possible.
If your cycle belongs in the picture
Protocol Her is the only app in this table that places doses and symptoms in menstrual cycle phase context, from the home screen through to the clinician report.
