### 2/5 — Scrolling issues

*2026-05-26*

I’m using iOS 26.6 on an iPhone 17 pro max.  In the vocabulary section, I can’t scroll down far enough to fill in the vocabulary answers at the bottom of the list.  Very frustrating.

### 2/5 — Bug

*2023-10-03*

App will not scroll to the bottom of the page in the vocabulary section

### 1/5 — what’s the point?

*2021-12-12*

this does nothing the book doesn’t: nothing interactive, no quizzes or drills, nothing creative at all. why not make little memory games to identify gerunds or graphics/pics to help assoc vocab words or there’s just so many things this app fails at-just buy a notebook instead

### 5/5 — Essential!

*2021-08-21*

Anyone using Wheelock should also be using this app. It takes all the drudgery out of memorizing vocabulary and paradigms. Fantastic app; Wheelock is authoritative but dull. “Principium” makes it fun!

### 4/5 — A nice companion app

*2019-12-05*

This is a very helpful addition to the Wheelock text. I love the glossary (especially the pronunciation!) and appreciate the form and vocabulary drills. It could use an update to fix overlapping windows, as data entry fields frequently obscure key information below.

### 4/5 — Excellent companion to Wheelock

*2019-11-21*

This is an excellent companion to Wheelock’s textbook.  Vocab practice, exercises, sentences, all very nice to have to practice.
	I do wish the developer would make it more IPad friendly.  That is making it able to autorotate, so a keyboard can be used with the app.

### 5/5 — Worth every penny

*2019-08-15*

Been using Wheelock for a couple of years now. This app has proved a vital part of my daily Latin routine - I use it to check vocab and forms, test myself, etc. I even use it when I’m bored on the train or waiting for someone; it’s incredibly easy to use. Thanks to the developers; you’ve released something incredibly helpful.

### 5/5 — As good as the book

*2018-10-17*

This app is perfect for anyone trying to get there Latin off the ground.  It provides a way to easily and efficiently review your Latin forms or vocabulary on the go.

### 4/5 — Good app, just one annoying problem

*2018-10-06*

Please allow a sideways view of the app! I cannot see the full definition of words with more than one meaning, such as cura, consilium, and many others. Other than that, it’s a fine app, and it gets the job done.

### 3/5 — Audio

*2018-07-30*

The app looks very helpful so far, however the audio isn’t working in the glossary. That was one of the reasons I decided to buy the full version. The audio icon appears when a word is selected but nothing happens. It’d be great to have this rectified. Thanks.
