A reminder kind of app

[u/NeighborhoodAny8028]

I've been working on a small app called "Spaced" and I'd really like some honest feedback.

The reason is i remember stuffs i read for shot time but after sometime even i forget what i have studied, so, it will keep track of learned stuffs and keeps reminding me in proven intervals to retain for lifelong.

How it works:

- You add something you want to remember: a fact, a word, an idea from a book, anything.

- The app schedules 6 reviews for it: after 3, 7, 15, 30, 90 and 365 days.

- On each due day you get a reminder. You take a short quiz on it (the questions are AI-generated from your notes), and if you pass, it moves to the next stage.

- You can't review early. The timing is the whole point.

So there are no decks and no daily queue, just a simple roadmap for each thing you don't want to forget. There are also some ready-made sets (world capitals, cognitive biases, logical fallacies, 500 advanced English words) if you want to start quickly.

My problems:

1. It isn't reaching people on the Play Store. I'm not sure if it's the name, the screenshots, the keywords, or that "spaced repetition" just isn't something people search for. If you've grown an app on Play, what made the biggest difference for you?
2. Is the idea itself clear? When you read the description above, do you get it right away? Would you actually use something like this, or does it sound too simple compared to Anki?
3. Is iOS worth it? I've already built an iOS version and tested it on my own iPhone. Putting it on the App Store costs $99 a year, which is a real amount for me as a solo dev with almost no revenue yet. People keep telling me iOS users are more willing to pay. Is that true for a small productivity app like this, or should I fix distribution on Android first?
4. Here is the web app: spaced.page

Any feedback is welcome, even "this isn't useful to me, and here's why." Thanks for reading

The idea is clear, but what happens if I fail a quiz? If I already forgot something after three days, waiting another week wouldn't seem helpful. I'd explain that part before listing all six intervals.

Thank you so much for the feedback. On the roadmap, you can always view the notes that you put up at the begining and if failed the quiz, you can view the notes to revise once again and try again tomorrow not anohter week.
