Verdict
The clearest difference is in-app purchases: ZeroSnooze at none against TechniCalc Calculator's 4. ZeroSnooze also leads on update cadence (every 4 days vs monthly) and price ($4.99 vs $7.99). TechniCalc Calculator's advantage is chart position (#186 vs unranked) and device support (4 vs 1). On ads there is nothing between them.
