What you get

ReadStack was built for exactly this.

The core features that make ReadStack different from the generic alternatives.

Two-tap logging

scan a book's barcode and it's marked 'reading' in under three seconds — no search box, no six-tap form.

Tracks paper and library books

Open Library powers the metadata, so the books you borrow or own in print count just like ebooks.

Your TBR pile, finally in one place

keep your to-be-read stack, currently-reading, and finished shelves without an algorithmic feed pushing the next thing.

Year-in-books insights

see your pace, genre mix, and reading patterns drawn from your own history — the part that rewards a habit once you've built one.

Honest streaks

a last-seven-days counter that nudges only when a streak's at risk, never a daily guilt-trip at 8pm.

Your data stays yours

sync runs through your own iCloud, and you can export everything to CSV or JSON whenever you want.

How it works

Three steps. No account. No tracking.

  1. 01

    Download once

    Install ReadStack from the App Store when the waitlist opens. No account setup — it works the moment you open it.

  2. 02

    Use for ninety seconds a day

    The product is designed so the useful thing takes less than two minutes. Anything longer and you stop. We know.

  3. 03

    Notice what changes

    Patterns surface after two to three weeks. The data is yours alone — no cloud, no report to anyone.
