Verdict
The clearest difference is price: Gas Checker at Free against Work Diary's $1.99. Gas Checker also leads on rating (5.0 vs 4.5) and update cadence (every 3 weeks vs every 2 months). Work Diary's advantage is ratings volume (51 vs 1) and review sentiment (76% vs 61%). On ads, in-app purchases, monetization model and device support 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
Gas Checker is free to download; Work Diary costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Gas Checker holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: Work Diary has 51 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 76% of Work Diary's written reviews are positive against 61% of Gas Checker's, so the app with the better star average is not the one people write more warmly about.
Work Diary ships an update every 2 months, Gas Checker every 3 weeks. The most recent releases landed on October 15, 2026 and September 30, 2026 respectively.
