VisualizerApp's core classroom visualizer is free: live camera, freeze, annotation, capture, and everyday teaching tools. Pro brings better classroom engagement with full-screen Tally, Spinner, and name-picking modes. It supports live modelled thinking with Presenter Mode, captures evidence mid-lesson, and lets you add names and save work with Lesson Decks. The app is built to supplement, not replace, your teaching.
For everyday live visualizer use with no accounts and no install.
Monthly Pro access for regular classroom use.
£39 vs £47.88 paid monthly, excluding tax.
A one-off payment for 12 months of Pro access. It does not auto-renew.
Prices are shown in GBP, excluding tax.
Assessment, modelling, and example feedback support teachers. A single hardware visualiser costs £80–£200 per classroom — VisualizerApp Pro can help support every classroom in your school for less.

Pro is for teachers who use the visualizer regularly and want less setup during lessons: smoother presenting, labelled capture, exports, and more reusable classroom tools.
Pro is a good fit if you use VisualizerApp a few times a week, regularly capture pupil work, or want quick exports for evidence, marking, and sharing.
Yes. The core document camera workflow is free to use in the browser. Pro is optional and helps support hosting, updates, and development time.
Use v3 Early Preview for the newest tools and interface. Use stable v2 when you need the most reliable version for a live class.
If you are using stable v2 and do not see an activation box, open Activate Pro in v3, enter your licence key, then return to v2. Pro access is saved in this browser and works across v2 and v3.
The Annual Pass works well for individual teachers and small teams. For more devices, licence keys start from £139/year excluding tax for up to 25 device activations.
When the 7-day Pro Free Trial ends, you can choose to buy. You can either buy a Monthly subscription or Annual Pass using the checkout handled by Lemon Squeezy, a third-party payments and licence-key service. VisualizerApp uses them so trial keys, payments, receipts, subscriptions, and Pro keys are managed outside the app and are compliant for legal and tax purposes. Monthly subscriptions can be cancelled from the Manage subscription link in your Lemon Squeezy receipt or subscription email.
Found an issue in v3? Please use the feedback form, or contact support support@inline-computers.co.uk if you need help or have a question.
VisualizerApp is a small one-person project based in the UK. It was built with the help of modern AI tools, but shaped, tested, and maintained by a real person.
The core app is free to use, with optional low-cost subscription and annual licences to help support hosting, updates, future features, and the time spent putting it together.
