Like everyone else, I can't recommend Pathbuilder 2e enough! I even paid for it although the basic version does almost everything (with ads). The only bummer is that the app and web version are separate purchase.

I always build characters by hand in any TTRPG. It's not complicated after you get the hang of it (after your first sheet).

If you don't need specific optional rule then pathbuilder is best. But if you need something like no level proficiency then wanderersguide.

On Foundry VTT I used the web version of Pathbuilder2e on my second screen and it was perfect.

People seem to forget http://pf2easy.com/ It is my favorite web site on the side to look for actions, condition, class feat, item, monster, spells, and everything else during the game.

Pathbuilder2e easily the best character builder out there. Also for GMs, they have a great encounter builder/combat tracker even with it being in beta. https://pathbuilder2e.com/beta/encounters.html

I highly recommend Pathbuilder, as well. It makes sure all the math is correct and nobody adds more or less than they're supposed to during character creation or level up while making it clear that something is off. You can even export the player info as stat blocks instead of as a character sheet. I used it to double check my party during character creation in FoundryVTT since it didn't have nearly as many guardrails.

Here are my only gripes, and they're all related. For context, I have the Android version:

-Unarmed Attacks aren't automatically added to the Offense category; they have to be added manually, which adds some tedium since even character can make unarmed attacks unless otherwise stated. -A number of ancestry traits that add special unarmed attacks, such as Taloned Tengu or the basic Sharp Beak, aren't reflected in the "Weapon" category for unarmed attacks, so you have to create a "custom" unarmed weapon to give the player, which adds tedium because you have to make sure you add all of the correct traits yourself and name it correctly. At least on mobile, you cannot switch from the custom weapon creation popup and the build tab without closing the popup first, meaning you can't reference the trait directly in the app while manually creating it in the menu. -If any custom/modified equipment is applied to the character, then those abilities will be labeled as 3rd Party with no way to remove the trait even if you delete it from the trait field during creation. So anyone playing an ancestry that Pathbuilder hasn't yet fully implemented will have "3rd Party" listed as a trait, adding unnecessary clutter and possible confusion. -Weapon creation requires picking 1-2 hands even if it doesn't use hands, such as a jaws or s beak.

For me it was a bit frustrating dealing with these particular issues since I have both a Gnoll and a Tengu in the party, both of whom have unarmed attacks in addition to fists, including ones which wouldn't use a hand.

If you're okay with filling in some of the gaps, then none of this should really be an issue. Everything else about the app has been lovely.

Edited to clarify, add additional info, and correct a spelling mistake.

Wait, I posted ... Oh, it's you again. :) unfortunately I can't help here, I use a VTT, so I don't need an external builder.

Well, I suppose I could use one, but it feels easier to spin up the VTT if I want to play with builds. That's what I get for GMing and hosting
