It sounds like spliktv apk 1.3 is a streaming service that allows users to watch TV shows and movies online. However, it is not a widely known service, and I would recommend researching it further to ensure that it is legitimate and safe to use. Be aware that not all streaming services are legal and many of them are not safe to use, as they may distribute copyrighted content illegally or include malware. It would be best to stick with well-known, reputable streaming services such as Netflix, Hulu, or Amazon Prime.
It would be good to check the reviews, ratings, and the number of installation of the service to get the idea of the app. Additionally, if you are unsure about the app please stay away and check more popular streaming services as mentioned above.
