Hey PH! I’m Leonardo, a 20-year-old software engineering student.
I built StackCards because I got frustrated with flashcard apps that forced me to create accounts, deal with bloated UIs, or pay heavy monthly subscriptions just to organize my study materials.
I wanted something fast, native, and completely private. StackCards runs 100% locally on your device, supports custom themes, code snippets, formulas, and vocab, and has a generous free tier. If you want everything unlocked forever, it's just a single, one-time purchase that directly helps me fund my university studies and Apple Developer fees.
I'd love to hear your thoughts, feedback, or feature requests. Let me know what you think!

Offline-first is a huge plus for me. One thing that would make it perfect is a simple spaced repetition algorithm built in, so cards automatically surface right before I'm about to forget them.

@saniye824360 yeah that's actually the #1 request so far haha. Right now it's got a smart-ish review mode (misses + old cards resurface more) but a real spaced repetition scheduler is on my radar for the next update. Thanks for trying it out!

Offline-first is a huge plus for studying on the go without worrying about spotty wifi. One thing that would make this a daily driver for me is importing my own decks from CSV or Anki format, since I already have a bunch of cards sitting in other tools and starting from scratch feels like a dealbreaker.

@evketzkaraostb totally fair, that's a real blocker. Import/export via JSON already works but Anki/CSV import is a great shout, especially since so many people already have decks sitting there. Adding it to the list

Love the offline-first approach and the one-time purchase model, that's rare these days. One thing that would make this a daily driver for me: a quick keyboard shortcut system for reviewing cards without touching the mouse, especially something like swipe-style shortcuts for marking answers as correct or wrong. Would speed up sessions a lot during exam crunch time.

@enesgryelfkhz ooh I like that idea a lot, swipe gestures already work for grading cards in study mode but a keyboard-shortcut version for faster sessions is smart, especially for the "cramming before an exam" use case. Noting it down

the offline-first approach is refreshing, especially for studying on the go. LaTeX support for formulas alone makes this worth the one-time price.

@melekmisp thank you!! yeah I spent way too long getting the math symbol keyboard right lol, glad it's landing well

the offline-first design is refreshing for studying on the go, and the formula support actually renders LaTeX cleanly which i didn't expect from such a minimal app.

@huriyeyr8y haha appreciate it, wasn't trying to overload it with features so happy the formula stuff still came through clean. Let me know if you run into anything weird with it

The offline-first approach with no cloud sync is such a refreshing choice for a study app, especially for code and formula decks where privacy and speed matter.
