The best library apps in 2026

Two apps, two licensing models, one library card, and a combined bill of nothing.

Short answer

Run both: Libby for depth and popular titles with holds required, Hoopla for instant gratification inside monthly caps. Catalogs overlap only partly, both cost nothing, and the multi-card trick in our free audiobooks guide multiplies what your cards can reach.

1. Libby 84/100

$0 with a library card · iOS, Android, Web

Free audiobooks and ebooks with a library card, in an app that is genuinely pleasant, and the friendliest ownership terms possible because you were only ever borrowing.

The catch: Holds queues on popular titles; the waiting is the price.

2. Hoopla 77/100

$0 with a participating library card · iOS, Android, Web

Instant borrows with no holds queue, capped monthly by your library, which makes it the perfect companion to Libby rather than a replacement.

The catch: Caps vary by library, commonly 4-10 borrows a month; catalog overlaps Libby only partly.

3. Kobo app 78/100

Free app; Kobo Plus from $9.99/mo — desk-checked, unverified · iOS, Android, Web

Broad format support, library borrowing built in, and a cheaper subscription in an ecosystem you can actually leave later.

The catch: Smaller store, plainer app; the lock-in table is where it wins.

4. Serial Reader 72/100

Free; Select upgrade $8.99/yr — desk-checked, unverified · iOS, Android

Ten minutes of a classic delivered daily, which is the lowest-pressure route into a reading habit that anyone has shipped.

The catch: Public domain only; contemporary readers graduate out.

Q & A

Questions readers actually ask

Libby or Hoopla?
Both. Libby has the stronger frontlist but queues it; Hoopla never makes you wait but meters you. Check Libby first, spend Hoopla borrows on what Libby would make you wait for.
Can I use two library cards at once?
Yes, in Libby. Adding a second card from a system you are eligible for roughly doubles your catalog and cuts hold times substantially.
