Project Assets and Sizes

It's best to keep app sizes as small as possible to preserve space on people's devices. All app projects have a 50MB limit, and free Thunkable accounts have a 100 MB total storage limit. If you need more storage for your account, you can upgrade to PRO to get 1 GB of space for your projects.

Thunkable PRO subscribers get 1GB of storage and can create unlimited public and private projects.

Account size limit

100 MB for Free, 1 GB for PRO.

You can view a project's app size on the project's details page:

The main contributor to an app's size are files (also known as assets). To add or delete files, click on the Assets button in the side bar. Then click the "+" icon to manage all the files in your project.

Operating Systems (OS)

While Thunkable often works on older operating systems, we only develop for operating systems that actively receive security updates (currently iOS 15 and Android 10, 11, 12).

Account storage limits

You can view your total account storage size in your account settings.

Free Thunkable accounts have 100MB of storage. PRO Thunkable accounts have 1GB of storage.

If you are near the limit, you may be able to create additional storage by removing projects that you no longer need like an old version or copy of a project.

We recommend that each of your asset files not exceed 50KB -100KB. Using smaller file sizes in your project will result in faster loading times for your users.

Naming Your Assets

Thunkable recommends using file names that do not contain whitespace characters.

Here are two naming methods we recommend:

  1. Snake Case - each space is replaced by an underscore (_) character, and the first letter of each word written in lowercase.

    • example_one.png

    • here_is_another_example.html

  2. Camel Case - writing phrases without spaces or punctuation, indicating the separation of words with a single capitalized letter, and the first word starting with either case.

    • exampleOne.png

    • hereIsAnotherExample.html
