How to choose freemium apps
Freemium apps pair a free plan with paid upgrades. The free plan is usually limited by usage, features, storage or team size, which lets you try the app on real work before paying.
Before choosing, compare the free plan's limits with how often you will use the app, check which features are paid only and what the first paid tier costs, and confirm that work made on the free plan stays available if you never upgrade.
