Leaving Cert Plus, A Study Platform for
Every Leaving Cert Subject

Mobile Apps, a Web Platform and an Admin Panel Serving Over 25,000 Irish Students


Study Material Exists. Finding The Right Piece At 9pm Does Not.

Discuss your project

A sixth-year student stuck on one maths topic the night before a test has plenty of options and no good one. Past papers without worked answers, textbook chapters that cover twenty topics to answer one question, hours of recorded lessons with no way in. What they want is the four minutes that explains this specific thing, then a question to test whether it landed.

Leaving Cert Plus was founded by Aaron Keane, who built his own study habits around audio recordings and flashcards while balancing school with competing internationally in athletics for Ireland, and later recorded short topic videos for the students he was giving grinds to while studying Medicine. Students preferred learning that way, and the platform grew out of it. Every video, note and exam explainer is made by a practising Leaving Cert teacher, and the company has since partnered with CJ Fallon, one of Ireland's most respected educational publishers, working with its CEO Brian Gilsenan.

We were the development partner behind the product, delivering three things: the Leaving Cert Plus app for iPhone, iPad and Android, the web platform, and the admin panel the team uses to run subjects, content, teachers and subscriptions. The platform now supports over 25,000 students, holds 4.5 stars on the App Store and 4.9 on Google Play, and has been featured in The Irish Times and the Irish Examiner.

Project Challenges & Needs

01

A Curriculum-Shaped Content Model

Every subject splits by level, then topic, then resource type, and the depth available differs by subject. The structure had to hold that unevenness without looking broken.

02

Entitlements Priced By Subject Count

Students buy one subject or all of them, monthly or as a single payment, so access had to be resolved per subject rather than by a single paid or unpaid flag.

03

A Curriculum-Shaped Content Model

A selection of content is open to anyone, so the same library had to serve visitors, free accounts and paying subscribers from one set of rules.

04

Video That Has To Play Anywhere

Hundreds of lesson videos needed to stream reliably on school wifi, on mobile data and on older devices, with playback speed control expected as standard.

05

One Account, Three Surfaces

Progress, flashcard state and purchases had to follow a student between the phone, an iPad and the browser without divergence.

06

A Syllabus That Keeps Moving

Content is mapped to the current curriculum, including new specifications examined in 2027 and 2028, so the team needed to restructure topics without a release.

Our Solution

We built a subscription learning platform across mobile and web on one shared backend, delivering:

Students studying with Leaving Cert Plus
Students using mobile devices
Subject hubs split by Higher and Ordinary Level, organised topic by topic
Bite-sized video lessons with variable playback speed from 0.75x to 2x
Exam-focused notes, worked examples and sample answers alongside each topic
Flashcards and quizzes for active recall, with state carried across devices
Real exam questions with explanations, searchable by topic
Audio learning for revision away from a screen
Search across the whole library, so a topic name returns video, notes and questions together
Free content accessible before sign-up, with free accounts converting to paid plans in place
Per-subject entitlements covering one to all subjects, monthly or paid once
Card and instalment checkout, with self-service plan changes, cancellation and refunds
Free teacher access verified by Teaching Council number, plus school and classroom access
An admin panel for subjects, topics, resources, teachers, users, plans and content publishing

The app and the web platform read the same content tree and the same entitlement rules, so a subject published once appears everywhere, unlocked for exactly the students who have paid for it.

Interfaces We Developed

Leaving Cert Plus App

Leaving Cert Plus App (iPhone, iPad & Android)

The study companion students carry, published on the App Store and Google Play and laid out for both phone and tablet:

  • Pick subjects and level, then open any topic within them
  • Watch short lesson videos with speed control and resume from where playback stopped
  • Read notes and worked examples, with tablet layouts showing notes and video together
  • Run flashcards on a topic, marking what is known and what needs another pass
  • Attempt quizzes and exam questions, then read the explanation for each answer
  • Listen to audio questions and revision material in the car or at the gym
  • Search by topic name and get every resource type for it in one result
  • Browse free content before subscribing, with locked items visible and priced
  • Manage plan, subjects and account from inside the app
Web Platform

Web Platform

The full study environment in the browser, for students at a desk and on devices they cannot install apps on:

  • Subject and topic navigation matching the app, with the same content and entitlements
  • Video, notes, flashcards, quizzes and exam questions in a wider working layout
  • Exam question practice by topic, with explanations and marking guidance
  • Sign-up, plan selection and checkout, including single-payment and monthly options
  • Account settings for plan changes, subject selection, cancellation and password reset
  • Progress and flashcard state synced with the app on the same account
  • Teacher and school access routes, verified before free access is granted
  • Works in any mobile browser with nothing to download

The control layer for the Leaving Cert Plus team, covering content, people and revenue:

  • Dashboard for students, subscriptions, subjects and resources
  • Subject and topic management, updated without an app release
  • Upload and publish videos, notes, flashcards, quizzes, exam questions and audio
  • Separate Higher and Ordinary Level content by subject
  • Free and paid resource settings
  • Teacher profiles and subject attribution
  • Teaching Council verification for teacher and school accounts

  • Usage reports for subjects, topics and resources

Key Features & Capabilities

Leaving Cert Plus Study Features
01

One Search, Every Resource Type

A topic name returns the video, the notes, the worked examples and the exam questions for it in a single result, which is how students say they use the product most.

02

Bite-Sized By Design

Lessons are cut to the topic rather than the class period, so a student can cover one thing in a few minutes and stop, with speed control from 0.75x to 2x.

03

Per-Subject Entitlements

Access is resolved subject by subject against the plan, so a student paying for three subjects sees three unlocked and the rest priced, on every device.

04

Study Away From The Screen

Audio questions and revision material make journeys and training time usable, the habit the founder built the original method around.

05

Active Recall Built In

Flashcards and quizzes sit beside the notes for every topic, making testing one tap from reading rather than a separate exercise.

06

Free Tier That Converts In Place

Open content and free accounts let a student prove the product to themselves, then upgrade in the app or the browser without leaving what they were studying.

07

Content Team Ships Without Us

Subjects, topics and every resource type are managed in the admin panel, so new syllabus coverage goes live without a code change or a store submission.

08

Teacher And School Access

Teachers verify a Teaching Council number for free access, with classroom and school options handled as separate account types.

Here's What Our Client Has To Say

We had a clear idea of how students actually study and needed a team who could build it properly across app, web and admin rather than a version of it. What we got back is stable, fast and easy for our own team to run, which matters when we are publishing content constantly. The student reviews speak for the result better than we can.
