Verdict
The clearest difference is in-app purchases: Keysight Meter Logger at none against Space DOT's 6. Keysight Meter Logger also leads on ads (none vs shown) and iOS requirement (7.0 vs 16.2). Space DOT's advantage is update cadence (every 9 days vs every 18 months). On price and device support there is nothing between them.
