Just had my first sale, but hard time growing and scaling

I just got my first paid subscription for Fasti, a schedule-planning app I built for students and part-time workers.
The app can turn schedule screenshots/PDFs into calendar events, handle class/work schedules, and help with things like shifts, deadlines, commute timing, and planning.
I’m happy about the first sale, but now I’m struggling with the next part: getting consistent users.
So far I’ve tried:

ASO
posting on Reddit
starting TikTok content
small TikTok Promote tests

For people who have grown an iOS app from basically zero, what actually worked best for you?
I’m especially curious about:

ASO vs short-form content
when paid acquisition starts making sense
how you got your first 100 real users
whether UGC creators were worth it
Brutal advice is welcome.

I built an app that turns class/work schedules into a calendar — looking for student feedback

Hey everyone,
I’m a student building Fasti, an iPhone app that turns messy class/work schedules into a calendar.
The idea: instead of manually copying your timetable, work shifts, syllabus dates, or schedule screenshots into Calendar, you can import them and Fasti builds a clean weekly schedule.

I’m mainly looking for feedback from students and part-time workers who deal with:

class timetables
labs/tutorials
work shifts
syllabi/deadlines
commute timing
pay/shift planning

I’m not looking for fake reviews — I’m looking for honest feedback on whether the app is actually useful.

What I’d love testers to try:

Import a real class/work schedule screenshot or PDF
Check if the events are extracted correctly
Tell me what feels confusing, broken, or missing
Tell me if this is something you’d keep using

Android beta: https://getfasti.com/android-beta

Brutal feedback is welcome.
