FAQ
Independent, self-funded, and free to use. Here’s how it all works.
We’re self-funded. There are no investors, no venture capital, and no ads, just the two of us. The app is paid for by readers who subscribe to Tilde Plus, so our only job is building something you want to keep using, not chasing growth or selling attention.
Yes. Tilde is free to download and free to use. Barcode scanning, your shelves, reading progress, and your reading stats are all free, with no limit on the number of books.
Plus unlocks whole-shelf photo scanning (one photo, dozens of books), series tracking with what to read next, a month-by-month view of the books you finished, automatic daily backups, and extra color themes. It’s also the most direct way to support an indie app.
Your library lives on your device. With Plus and an optional sign-in, Tilde also backs it up daily so you can restore it on a new phone. Photos you use to identify books are sent to our server for recognition and aren’t kept afterward.
Not yet. Tilde is launching on iPhone first, and Android is coming in the next few months. Email us and we’ll let you know when it’s ready.
Free to download on iPhone. Android is on the way.
