well if you're doing in online preparation for NEET UG at least then I would refer the byju's app to you apart from entrance360 package provided by careers360 which will also give you a good idea regarding the subject

however if you would ask me about online biology books available then I would recommend Veer Bala Rastogi or Truman volumes to you all the these books including Dinesh and Pradeep are widely available offline as well so I wouldn't understand why you would want to purchase or study them online for that matter
