Hello community, how are you?
I am trying to create a freemium style application, it is a stock control application.
Where the free user can only add 5 products to control the stock and the paid user has no product limit.
The problem is that I cannot think of how to impose this limitation in case the free user tries to upload 6 products, does not allow it and shows an error message.
Does anyone comes up with something?
Thanks as always 
Hi there!
It’s easy.
You must be having an add product button which links to an add product screen.
So create a true false property in the users collection - ‘premium user?’
Then create 2 add product screens - one for premium users and 1 for fee users.
Now create 2 actions on the add product button with the advanced option = on for the button
Action 1: link to add product screen for free users
(this action happens sometimes when ‘premium user? = false’)
Action 2: link to add product screen for premium users
(this action happens sometimes when ‘premium user? = true’)
I hope this solves your problem!
Thanks for your answer, but this still does not solve the problem of the limits.
If I want the free user to only be able to load 5 products for example?
Add a new collection called ‘product count’
Property 1 - Name
Property 2 - User (relationship - user can have multiple product count, a product count belongs to 1 user)
Now in the add product screen for the free user do this:
In this screen there will be an icon like maybe - ‘add to cart’
On this icon put an extra action - Create Product count (name = empty, user = logged in user)
Now add 1 more extra action to this button:
Link to ‘Upgrade to Premium’ Modal
with an advance condition:
‘Current user --> Product count --> count’ is greater than 5!
I hope this would solve your problem!
Thanks, use something similar. But also using component visibility.
For example, I have a single form (premium and free), both can access, but create a button that directs the user to the form if they have less than 5 items in the collection. If you have more and it is premium, the button is hidden and an exclusive button for premium users appears that removes that limitation.
Hi,
My apologies for interfering - just wanted to warn you about Apple’s policy of in-app purchases, so that the app might be blocked for App Store publishing. As I understand, Apple requires to process the payments for non-physical products via their purchases system, and Adalo doesn’t support it yet (AFAIK).
Just a gentle warning - stumbled upon this issue (not sure reg. Google).
Best,
Victor.
It is not a problem because I am creating a web app, so the memberships are managed from a web, not from the app.
But thanks for clarifying it, it may be something interesting for everyone who is creating premium apps.
