MechTime “Machines do not simply grow old. Time spent caring for them leaves its own rings.” A thoughtfully crafted car-care app, for those who love their cars. Keep a record of every careful service, stay mindful of what comes next, and bring a little ritual to the passing of time. A car shares much more than mileage with you. MechTime gives those everyday journeys a place to belong. From vehicle details to maintenance, repairs, modifications and costs, turn the moments of ownership into a traceable timeline — a complete archive for every car. Between warm textures and quiet starlight, Pro's animated timelines and custom welcome screens make each visit feel like meeting an old friend. When the journey welcomes its next companion, you can pass on more than a set of keys. With Pro's vehicle timeline handover, share the maintenance rules and history you have carefully built, choosing which personal details to leave out. Let the next owner see the care that brought the car this far. As the rings grow and the stars turn, here is to the golden age we love. FEATURES AND PURCHASES Start with one vehicle for free: basic records, cost summaries, custom maintenance rules and reminders, standard timelines, two visual themes, and full personal backup and restore. Pro is a one-time purchase, with no subscription. It unlocks multiple vehicles, photo and file attachments, animated timelines, PDF record lists, vehicle timeline handover and custom welcome screens. The current price is shown in the app. Both sender and recipient need Pro for vehicle handover. Preview the content and choose whether to include costs, workshop and technician details, notes and attachments. Import adds a vehicle without overwriting existing profiles. Review all content before sharing: text, photos and files may still contain personal information. Vehicle handover is not a substitute for a full personal backup. Available in Simplified Chinese and English. Costs are recorded in CNY; distance is measured in kilometres. Check maintenance rules against the actual vehicle, its handbook and professional advice. MechTime is an independent owner tool and is not affiliated with or endorsed by any vehicle manufacturer.

Verdict
The clearest difference is rating: 机械年轮 at 5.0 against U8's 4.1. 机械年轮 also leads on ads (none vs shown) and update cadence (every 3 days vs every 6 weeks). U8's advantage is ratings volume (10 vs 1) and device support (3 vs 1). On price 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. U8 sells 1 one-off in-app purchase and 机械年轮 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
机械年轮 holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: U8 has 10 ratings behind it against 1, so its average is the more settled of the two.
U8 ships an update every 6 weeks, 机械年轮 every 3 days. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
