My Jump Log — Product Guide
My Jump Log is a free digital skydiving logbook. Log jumps and collect signatures in the app; records sync to a Google Sheet and signature images save to your Google Drive.
Your records, in your Google Drive
Jump records live in your Google Sheet and signature images in your Google Drive. The developer does not operate a central database of jump records. You can access your files directly without using the app. Removing the app or revoking its access does not delete existing Drive files.
Free, independently developed
My Jump Log is offered free of charge. Its creator is an active skydiver with 500+ jumps who built it for personal use and shares it with other jumpers. Low running costs make it practical to keep the app free.
Mobile and multiple devices
The app is a Progressive Web App for iPhone and Android. Use Add to Home Screen on iPhone or Install App on supported Android browsers. Sign in with the same Google account on another device to discover and reconnect an existing logbook.
Offline logging and signing
You can log jumps and collect signatures offline. Pending changes remain in browser storage on that device until successfully synced. Device loss or clearing browser data before synchronization can lose pending records. Check Pending Upload status and verify important records and signatures in Drive.
Logbook fields and acceptance
My Jump Log includes the logbook fields required by USPA SIM §3-1. It is not officially verified or endorsed by USPA and does not guarantee acceptance by any official or dropzone. Skydivers and signers must ensure records are accurate and meet applicable requirements. It is a record-keeping tool, not a safety or flight instrument.
Google permissions
Drive access is limited to specific files created by or explicitly shared with the app. It does not grant general access to your Drive. Consult the Privacy Policy for details.
Start now; add history later
Choose a starting jump number without entering past jumps first. Adding paper records is optional. There is no built-in importer; existing records can be reorganized to match the current Google Sheet, including with an AI tool. Use your sheet’s current column headers and a sample row as the target format. Keep original signed paper records for Paper Verified entries.
