RevDue keeps your motorcycle maintenance on schedule. Track every bike in your garage, log services as you do them, and always know what's due next — by mileage or by date. WHY RIDERS USE REVDUE • Service reminders that match your bike — oil, chain, brake fluid, coolant, tires, valve checks, and your own custom services • Set intervals from your owner's manual — defaults get you started, your manual gets it right • Chain-drive bikes automatically get chain lube and replacement reminders; belt and shaft bikes don't see them • Log services in seconds: type, date, mileage, cost, notes • Update your odometer and every reminder recalculates instantly • Time-based reminders can notify you — even when the app is closed • Full service history per bike, including what it cost SIMPLE BY DESIGN No ads. No analytics. No subscription. Your data syncs securely to the cloud and belongs to you — export-free, tracker-free, and deletable any time. The free version includes every feature for one bike. A single $2.99 purchase unlocks unlimited bikes, forever. Built by a rider who got tired of guessing when the last oil change was.

Verdict
The clearest difference is review sentiment: RevDue at 100% against G SHELL's 19%. RevDue also leads on rating (5.0 vs 2.4) and update cadence (daily vs every 2 weeks). G SHELL's advantage is monetization model (free vs free with in-app purchases) and ratings volume (7 vs 1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. G SHELL sells 5 in-app purchases, starting at $4.59 per month and RevDue sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
RevDue holds the better App Store score, 5.0 against 2.4. That said, the two scores are not equally well evidenced: G SHELL has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 19% of G SHELL's written reviews are positive against 100% of RevDue's.
G SHELL ships an update every 2 weeks, RevDue daily. The most recent releases landed on September 22, 2026 and September 9, 2026 respectively.
