Eat small. Grow bold. Survive the Apex. Massward is a solo cell-survival roguelite set in the Sunreef. Drag to steer, absorb smaller organisms, and split for a risky lunge. Every dive moves from calm waters into the Hunt, then brings a charging Apex predator. NO ADS. JUST ONE MORE DIVE. Play Daily Dive and unlimited Endless runs free. No matchmaking, no chat, and no interruptions from ads. EVOLVE DURING EVERY RUN Draft mutagens as you level up. Stack movement, pellet yield, split power, wards, and other traits to shape your organism. Watch the warning line before an Apex charges, and leave yourself a way out. BUILD BETWEEN DIVES Spend earned biomass on permanent mutations for Endless. Collect shards to add draft choices or favor a gene in the Splice Lab. Your Idle Vault cultures biomass while you are away; collect it before it fills and buy cultures to increase production. ONE OCEAN. EQUAL STARTS. Daily Dive gives everyone the same seeded arena, a 10-mass starting organism, and three seeded draft choices. Permanent upgrades and Splice Lab perks stay in Endless. Your first Daily dive ranks by peak biomass from the moment it begins, even if you end it early; replays are practice. New boards arrive at 00:00 UTC, with streaks and personal records to keep you coming back. FREE TO PLAY • Daily Dive, Daily rankings, and practice • Unlimited Endless runs • Metabolism and Motility mutations • Idle Vault, cultures, and Splice Lab • No ads OPTIONAL PRO Unlock Combat and Yield mutations plus daily Ops with claimable biomass rewards.

Verdict
The clearest difference is ads: Massward at none against Mars's shown. Massward also leads on update cadence (weekly vs monthly). Mars's advantage is device support (4 vs 2) and iOS requirement (12.0 vs 15.1). On price and in-app purchases there is nothing between them.
