## What is Sign.Plus?

Sign.Plus is a legally-binding electronic signature solution to sign documents on iPhone and iPad devices and send documents for signature. It’s secure, reliable, cross-platform, and super easy to use.

Using this free eSignature app, you can fill and sign PDF documents, Word documents, and other types of supported documents. You can also utilize the paper scanning feature to convert your paper documents to digital documents and sign them electronically.

√ Sign.Plus recognized as the best e-Signature solution to fill and sign documents!

◆ Fill and sign documents: Sign.Plus allows you to create an electronic signature to e-sign documents wherever you are and whenever you want. You can draw a signature, type your signature or use your initials.

◆ Send documents for signature: Other than the option to fill and sign documents yourself, you can also send documents for signature. You can send a request for signature even if the signees do not have a Sign.Plus account. You can add various fields to the documents, including signature, initials, date, text, and checkbox.

◆ Tamper-proof audit trails: For every document that goes into the process of signing electronically, there are real-time logs to keep track of any activity that has occurred with information such as name, IP address, email address, device, and much more. The audit trails are non-editable and each document action is thoroughly tracked and time-stamped, serving as legal proof of receipt, review, and signature.

◆ Legally-binding electronic signature: Sign.Plus complies with electronic signature regulations such as ESIGN, eIDAS, and ZertES to ensure it delivers the same legal standing as pen-and-paper signatures.


► Extensive security measurements and compliance offerings

◆ Data encryption: We encrypt all documents at rest using 256-bit Advanced Encryption Standard (AES), with each user’s unique encryption key. Furthermore, to protect data in transit between our apps (currently mobile, API, web) and our servers, we use TLS 1.2+ encryption.

◆ Various compliance offerings: We are committed to certifying ourselves and our e-signing platform for all relevant certifications and compliances, including SOC 2, HIPAA, ISO 27001, GDPR, CCPA, and more.

### 1/5 — Ужасно

*2026-02-11*

Не работает

**Developer response:** Здравствуйте! Сожалеем о неудобствах. Пожалуйста, проверьте наличие обновлений Sign.Plus в App Store и перезапустите приложение. Если проблема сохраняется, напишите нам на support@alohi.com, мы поможем.

### 1/5 — Bait & Switch

*2026-01-31*

Horrible app interface. Nearly impossible to use on your phone, required if you want to edit a doc prior to faxing with its corresponding app, and overall horrible experience.

**Developer response:** Hi, we know editing on mobile can feel challenging. In Sign.Plus tap Fill to open your document, then tap or drag fields to add signatures or text. For personalized help, email support@alohi.com—we’re here to help!

### 1/5 — Awkward App

*2025-09-27*

Unfortunately, this app is not very intuitive. It does not remember you and you need to log back in almost every time you use it and reset your password. If you receive the fax upside down, there’s no easy way to flip it and sign it. So I end up sending faxes signed upside down, looking very unprofessional.  It needs a rethink with consultation to users.

**Developer response:** Hi, This is Rajat from the developer team. Thank you for the feedback. We are looking into the logout issue and it should be fixed soon. Please write back to us at support@alohi.com in case you continue to face that issue on your app. For the rotate issue: You can rotate your received faxes from the 3-dot menu and then send to Sign.Plus to sign. This way your documents won't be upside down when you sign them. Hope this resolves. Alohi Team
