The clearest difference is price: PumpX at Free against Sun Nudge's $2.99. PumpX also leads on ratings volume (41 vs 2) and iOS requirement (15.6 vs 18.0). Sun Nudge's advantage is in-app purchases (none vs 32) and ads (none vs shown). On update cadence and device support there is nothing between them.

PumpX is free to download; Sun Nudge costs $2.99 up front. PumpX sells 32 in-app purchases, starting at $4.99 per month. Sun Nudge asks for nothing beyond the download.
