Is there a safe non-cheating way to play on my laptop?

No. Quit trying to cheat.

Pretty much. Thousands of players have cheated. What happened to them? The keep on paddling.

I wish there was a desktop app that just allowed us to just view our pokemon, appraise, evolve, power up, and make transfers. Would probably make a lot tedious aspects of the game faster than cellphone.

EDIT: For the people downvoting, didn't mention pretending to walk around. Just inventory management. Stuff that you could do sitting at home but without the lag from constantly processing GPS location and rendering the map under everything.

Borrow a phone from a friend or relative.
Use your tablet if you have one.
Install a Nougat-based ROM on your phone and use the screen in split mode.
Get your screen fixed.

Borrow a phone from a relative / friend

You could try some remote control thingy like TeamViewer. Essentially this will be screen sharing so the game is running on the phone and you can interact with it from a computer.
I usually use it the other way so my phone can access my home computer.

Buy a new phone lol.

I am on ios, so i use iphone when i playing outside, and ipad on my home wifi, to check IV,evolve, powerup, transfering mons.
Easier for my eyes with bigger screen..
