Our honest verdict
GoTall has real scale — a large install base and a good average rating — but the pricing and data-deletion complaints from users are worth knowing about before you subscribe. Zenith's free, no-subscription prediction sidesteps that risk entirely, though GoTall's larger user base means a more mature exercise library today.
