Verdict
The clearest difference is price: DigiLEAN at Free against Sampling Calculator's $5.99. DigiLEAN also leads on update cadence (every 3 months vs every 16 months). Sampling Calculator's advantage is chart position (#173 vs unranked). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
