A signature that means what you meant.
Free accounts, drafts and templates for routine work, 43.9 and 43.11 fields prompted instead of remembered, and a signing step that binds your name and certificate to exactly the version you reviewed.

Your account is free. It stays free.
The owner pays for the aircraft. Mechanics and apprentices pay nothing, on every aircraft they're invited to.
An owner invites you onto their aircraft's record, or you start an account and they add you. Either way, your certificate and your signatures come with you from airplane to airplane.
If you leave
A departing user leaves with their records. The entries you signed stay on each aircraft's record for the life of the aircraft, with your signature intact.
Drafts, templates, and the 43.9 and 43.11 fields in front of you.
Write the entry as a draft while the cowling is still off, and finish it when the work is done. Save templates for the work you do every week: the oil change, the 100-hour, the annual.
The entry form prompts for the content 14 CFR 43.9 and 43.11 call for: the description of work, where it was done, who performed it, any discrepancies, the date, and the aircraft's total time. A missing field is flagged before you sign, not found at the next prebuy.
Whether a record is acceptable rests with the mechanic and the operator, exactly as it does on paper.

Sign exactly the version you reviewed.
The signing flow follows the electronic-signature practices in FAA Advisory Circular 120-78B.
Review the exact version
You read the text you're about to sign, as it stands now — not a summary, not what it said five minutes ago.
Re-authenticate
Prove it's you again at the moment of signing. An open session on the shop computer isn't enough.
Sign
Your name and certificate number are frozen into the signature on that exact version.
Seal
The entry is hashed and becomes append-only. A later change would be detectable.
Signing follows AC 120-78B practices.Your certificate, frozen into each signature.
Every signature records the signer's name and certificate as they stood at the moment of signing. If your ratings change next year, last year's entries still show what you held when you signed them.
Checking a certificate against the FAA airman registry coming is an assisted check: it gathers evidence for a human reviewer and never makes the decision on its own.

Corrections go through the signer. Never silent edits.
A signed entry is yours. Nobody else can revise it: not the owner, not another mechanic, not us.
The owner requests
A wrong part number, a transposed tach time. The owner requests a correction with a note; they can't change the entry themselves.
Only the signer revises
You decide whether the correction is right. If it is, you write the corrected version and sign it the same way as the original.
A new linked version
The correction is a new version linked to the original. The original stays in the record, so anyone reading it later can see what changed and who signed the change.
Print it, paste it in the paper logbook.
Every signed entry can print as a label with a QR code. Paste it in the aircraft's paper logbook next to the old handwritten entries, and the two books stay tied together.
Anyone who scans it, an inspector or a buyer's mechanic, can check that the record still matches what you signed, with no account. What a scan shows

Apprentices log Part 65 experience. coming
Apprentice accounts are free today. The Part 65 experience log coming will let apprentices record the work they do toward the A&P, with a supervising mechanic signing each record.
When it's time, the log assembles an evidence packet to take to the FSDO. The FSDO decides; the packet just keeps the evidence in one place.
Get invited or start an account.
Ask the owner to invite you onto their aircraft, or start an account and let them add you. Mechanic and apprentice accounts are free.
