### 5/5 — Perfect for business coaches

*2021-02-27, version 2.4*

After exhausting many different methods for capturing inspirational quotes and actionable insights, I’ve finally found my solution. One of my favorite features is the ability to use tags to cross reference similar topics from different authors and books. If you are an avid learner or would like to benefit more from all the reading you do, give Tertius a try.

### 5/5 — Like fine wine Tertius gets better with time

*2020-07-31, version 2.3*

This app has gotten better and better with every use. Now I’m to the point where I don’t pick up a book to read without it. Collecting quotes and ideas from various works helps me to better interact with and remember what I’ve read and makes it much easier to come back to later. Great app.

### 5/5 — An Indispensable Resource

*2020-07-23, version 2.2*

I wish I knew about Tertius while I was working on my Masters at Grand Rapids Theological Seminary. It is a must have for every grad level student and an indispensable resource for every reader and leader who wants to retain their favorite phrases and paragraphs. And, I love how open the Tertius team is to receiving feedback and responding quickly with valuable updates.

### 5/5 — The Best App for Scholars!

*2020-07-17, version 2.1*

Perfect app for scholars. It allows me to have my cake and eat it too. I get all the tech benefits of on the fly note taking, thought organization, and bibliographic references digitized for easy search and recall AND I get to keep the joy of feeling the weight of actual books in my lap, the texture of turning real pages in my fingers, and the wonderful smell of a library of books that are older than I am.

A truly great blend of old school sensibilities and new school efficiency.

### 1/5 — Test Your Links, it’s broken

*2020-03-18, version 1.9*

I downloaded your app, i clicked to sign up by email and then it we sent you something to your email to sign up 
And the link provided in the email is broken

### 5/5 — Great tool for a busy mom

*2019-10-14, version 1.9*

Being a mom of three young boys means time for reading comes in small doses. This app has made those small doses count. Tertius is easy to use and makes reading more enjoyable. It’s my reading highlight reel!

### 5/5 — Finally!!

*2019-06-14, version 1.8*

Finally someone has come up with a way to more accurately capture text from reading. I am constantly reading and physically capturing high points in Evernote. It takes time, more than I’d like. This greatly reduces that time. Way to go!! Now, if only you could integrate with Evernote;)

### 5/5 — Exactly what I have been looking for!

*2019-05-15, version 1.4*

I am a student pursuing higher education and I have been frustrated by my inability to capture quotations and organize them into an easily searchable platform for use later. This app does that perfectly. The functionality is exactly what I have been looking for and the design is beautiful!
