1st Launch with or without a mobile app?

I've scheduled my launch for tomorrow, but I decided to reschedule it because I also want to include a link to the mobile app in addition to the web app. According to some statistics I came across, people are more often on their phones while browsing the internet. I found myself preferring to do some activities on my phone rather than in front of a PC. I'll be launching Franglishor soon, which is a Grammarly-like app but hands-on (more of a writing trainer than a writing assistant), multilingual, and free (a limited number of interactions per day to proofread and translate your texts).
