Hey @mappo, welcome on Actifit!
Sometime could happen to forget opening the app: personally, I try to leave it always open!

I suggest you another awesome mobile app for better interact on the Steem: Partiko!

Give it a try! Clicking on the above link from your mobile phone, you'll be automatically redirected on the right download and install procedure for your device.
I'll also give you some tips to obtain the best results from the use of partiko,

Cheers!
