I am about to launch my app in a few days on the stores and I was wondering if the number of users has an impact on the app performance: a few users vs a few thousands users vs a few dozens of thousands users?
If I use an external collections like Airtable or Google Spreadsheet, should it improve the app performance?
The question is not the number of users you have, but the number of active users, using your app at the same time.
And the answer is yes, it will have an impact. Just like with websites and web apps, the more users use the tool at the same time, the more load on the servers.
That said, I’ve heard of apps built with Adalo that have thousands and millions of users, and they work just fine. That said (again), I don’t know how many active users are using the app at the same time.
Yes, using an external database like Airtable or Xano will help performance as long as you limit data the user sees at one time via filters. Also, the more complex an app is regarding number of screens and number of lists per screen the slower the app will run.
