What do people worry about with free signing apps?
BoldSign answers the five questions people ask most before they trust a free signing app.
Is it a trial in disguise?
No. The Essential plan costs $0, it is not a trial, and you sign up without a credit card.
Will I run out after a few documents?
The allowance renews every month. The comparison below sets it against the other free plans.
Do my signers have to sign up?
No. Your signers open the email link and sign in a browser, with no app, account, or payment.
Will the signed copy hold up?
Every completed document comes with an audit trail of who signed, when, and from which IP address, and BoldSign adds no watermark.
So what is the catch?
No catch. Every limit of the free plan is listed in the limits section.
How do you sign a document on your phone?
With the BoldSign app, you sign documents sent to you, or place fields on your own document and send it by email. Each signer’s progress then shows in the app.

Does BoldSign add a watermark on the free plan?

What happens when I reach the free limit?
BoldSign asks you to upgrade when you have used your envelopes for the month. The next plan up, the Growth plan, costs $5 per user a month, billed yearly, and sends 50 envelopes a month for each user. Every plan is listed on the BoldSign pricing page.
Can I scan a paper document and sign it?

What is the best free document signing app?
