Verdict
Battery Testing and BAST both sit at 4.5 stars, but that hides the real split: 76% of BAST's written reviews are positive against 23% of Battery Testing's. BAST also leads on in-app purchases (none vs 1) and ads (none vs shown). Battery Testing's advantage is ratings volume (12K vs 310) and iOS requirement (13.0 vs 17.0). On price, rating, update cadence and device support there is nothing between them.
