HLO is a full character generator, not just character sheet tracking but complete rules support. For example, it handles the full effects of polymorph-type spells, including adjusting various stats and adding/suppressing abilities, and it calculates all the stats of derived sub-characters like familiars and mechanic drones. It also has support for a combat tracker that can pull in a full library of bestiary stats and use live character sheets as a data source for the stats in the tracker (including the effects of spell buffs on individual sheets, etc). Since it's licensed content rather than OGL, it also includes the full unredacted text for everything, which makes it really useful as a reference, both for things already on character sheets and for general looking up things by name.

Also, I think you're wildly miscalculating the pricing. It's $5 per 4 months (or $15/year, effectively $1.25/mo) for an Apprentice subscription or $50/year ($4.16/mo) for Patron. A Patron account can create campaigns that share any purchased content with other accounts that have a character in that campaign, where Apprentice is the minimum level to get access.
