I think I'm facing many problems concerning the use of tense when I write things..so is there any app or website that can check my mistakes and correct them?
Correct them, no. But a tool like AutoCrit can highlight all verbs written in a specific tense. I've never actually used this tool before so I can't speak to its quality, but you might find it helpful.
Keep in mind no fancy proofreading program actually understands your writing. While a program might detect a verb's tense, it can't detect whether your slip into past perfect is an accident or an intentional flashback to a past event.
If you need to brush up on verb tenses, I can recommend this web site.
