Namely, if I’m reading an epub file, whenever I exit the document and then re-enter the document, or sometimes the screen is turned off for a while and I resume reading, I always jump to the very beginning of the section I’m reading. I have to scroll all the way back to where I was reading. If the section I’m reading happens to be long, it actually takes a while for me to relocate where I was. This issue doesn’t occur to some other e-book reader apps, like Apple Books. I hope the developer can fix this issue in the future. ### 5/5 — great to digest pdf or any docs *2025-09-01, version 3.7.30* get a clear picture of content the interactive way for any doc.. it’s a favourite ### 4/5 — La compra de la aplicación es compra única, mensual o anual ? *2025-03-31, version 3.7.30* Es una excelente aplicación lástima que no aparece las indicaciones e instrucciones en español ### 5/5 — Nagyon jó *2025-02-11, version 3.7.30* Nagyon szeretem, tökéletes jegyzetelő app. A szakdoga íráshoz megkerülhetetlen segítség, imádom hogy pontosan vissza tudok keresni mindent, bármilyen könyvben. Idézet rendszerezéshez is tok jó. ### 1/5 — Never syncs, scam *2025-02-09, version 3.7.30* Don’t trust developers ### 1/5 — Worst customer service *2025-01-24, version 3.7.30* Worst customer service ### 5/5 — Bitte auch für Windows! *2024-12-17, version 3.7.30* Super App für Notizen und Lernen!
