Find the series first, then compare its browser and app reading routes. A free-chapter promotion is useful for sampling but does not establish that a whole series can be read without payment. Check the chapter’s current unlock conditions before moving between devices.

For the English catalogue, Daily Pass and ad unlocks are app-only and last 72 hours; the Daily Pass renews 23 hours after use on that series. Newest chapters need Keys. Keep a login if you want purchases across devices, since guest purchases can be lost with the app install. Offline reading is not available, and country licensing can exclude a series.
