Verdict
The clearest difference is review sentiment: Relog at 100% against Date Calculator's 64%. Relog also leads on rating (4.9 vs 4.5). Date Calculator's advantage is ratings volume (198 vs 31). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Date Calculator sells 4 in-app purchases, starting at $3.99 per month and Relog sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Relog holds the better App Store score, 4.9 against 4.5.
