Verdict

The call

The clearest difference is price: SwitchPDF at Free against GriDot's $2.99. SwitchPDF also leads on update cadence (every 2 weeks vs monthly) and device support (3 vs 1). GriDot's advantage is ads (none vs shown) and iOS requirement (13.0 vs 15.0). On in-app purchases there is nothing between them.
