Steer left and right to weave through asteroids, black holes, and the strangest phenomena in the universe. Every hit drags you below light speed; stay clean to keep your distance climbing. DODGE THE UNIVERSE Solar flares, pulsars, quasars, gravitational lensing, quantum tunnelling, dark matter, supernovae and more — each is its own hand-crafted set piece with its own trick to read and beat. Discover new theories as you run and they unlock in your codex. A LAB THAT'S YOURS Between runs, explore your laboratory. Spend the Bits you collect on power-up particles, new scientists to fly, galaxy backdrops, and playful lab gadgets — tap the disco ball, the Tesla coil, Schrödinger's cat box, and more. POWER-UP PARTICLES Stock particles like the Neutrino, Electron, Higgs Boson, Dark Matter and Antimatter, then grab them mid-run for a burst of speed, double Bits, a shield, a Bit magnet, or a clean sweep of the field.

Verdict
The clearest difference is in-app purchases: Spacetime Sprint at none against Cell to Singularity's 21. Spacetime Sprint also leads on ads (none vs shown) and update cadence (every 3 days vs every 2 weeks). Cell to Singularity's advantage is ratings volume (23K vs 3) and chart position (#139 vs unranked). On price, device support and iOS requirement there is nothing between them.
