Quiver vs ChainLog
ChainLog calls itself "your bike's health record," and its distinctive idea is proof: a signed, verifiable maintenance history you can show a buyer. Quiver is a spec catalog. These two overlap less than any other pair on this site.
The short version
Pick ChainLog if what you want is a verified service history, especially if you plan to sell the bike and want evidence it was looked after. It is free, it runs in a browser on any device, and it does the resale-proof job that nobody else here attempts.
Pick Quiver if the gap is knowing what is on the bike at all. Quiver does not track service or produce a certificate.
| Quiver | ChainLog | |
|---|---|---|
| Main job | Know exactly what is on each bike, and what it cost | A verified service history you can prove to a buyer |
| Getting a build in | Name the bike, and the catalog fills in the complete factory build | Their site does not document how the bike and its parts get entered |
| Source shown for each spec | Yes, and unconfirmed values are marked | Grades ride data as verified, imported or declared, which is the same instinct applied to mileage |
| Per-size geometry | Yes | Not something they list |
| Service tracking and reminders | No, by choice | Yes, its core feature |
| Signed resale certificate | No | Yes, with a QR code and a health score |
| Ride sync | No | Strava, Ride with GPS, GPX import |
| Cost tracking | Yes, including what you have invested over time | Yes, including scanning a receipt |
| Price | Free, or $9.99 once for Pro | Free, no ads, no paid tier listed |
| Platforms | iPhone today, Android in closed testing | The web, so any phone or laptop |
What ChainLog does better
It is free, it runs anywhere with a browser, and the signed maintenance certificate is a genuinely good idea that no other app here has. If you sell bikes regularly, that proof is worth real money at the point of sale. It also tracks maintenance cost per component and can read a receipt photo.
What Quiver does better
The build itself. ChainLog records what you did to the bike; Quiver works out what the bike is made of. Name it and the factory build comes back part by part from the catalog, each spec carrying its source, with per-size geometry for the next-bike decision. If you want a record of the parts rather than a record of the servicing, that is the difference.
Can you use both?
Yes, and the pairing is unusually clean, because one holds the parts list and the other holds the service history. Neither tries to do the other's job.
