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 200 MB total storage limit. If you need more storage fo your account then 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.
