by apps, what do you mean?
If you mean tasks, they reward nicely but can only be done once and that's it. Depending on your region, there could be a ton of games or just a few, and reward amounts also vary
If you mean Contracts... those things are weird. Some times they reward, sometimes they don't. I believe there's a way to contact support for each wall of contracts but... Judging by experience, they're kinda unreliable. At least for me
If you meant the App Zone, you can get up to 100 SG per day. Do it every day and you get 700 a week!
