Tiiks vs Bikebook: Strava on Catalog Parts vs an Honest Offline Notebook

Bikebook Wrench Log is a private, free, on-device chain-stretch notebook in TestFlight and the browser. Tiiks is a finished native app that puts Strava on named catalog parts with reviews.

You put the checker in the chain, read 0.75, and want a verdict that does not require an account. Bikebook Wrench Log, from All Things AI, Inc. at allthingsn.com/apps/bikebook/, is built for that kitchen-table moment: free, no subscription, no login, nothing in a cloud, no Strava. The stretch number becomes “replace now” or miles left. The ride you tap rolls onto every fitted part. That is an honest offline notebook. It is also a TestFlight beta and an in-browser tool, not a finished App Store listing. Say that out loud before you compare icons.

Tiiks is a shipping native app on iOS and Android. Strava distance lands on the bike and on each fitted component. The part is a catalog object with specs. Reviews carry real mileage. Service or replace. Full history. A widget. Twenty slots. They win privacy, paywall, and the measured checker. We win the identity of the part and the rides you already recorded. Pretending the beta is a store competitor, or pretending a catalog needs your iCloud password, wastes both products.

What Bikebook Wrench Log actually is

Bikebook is iPhone, iOS 17 and up, plus a browser version that stays in the browser — they say nothing is sent to their servers. No account. No Strava. No cloud. A garage of bikes; per-component miles on chain, cassette, chainrings, pads, tyres, cables, bottom bracket, and sealant, each with an install date. The chain-wear calculator takes a 0.25 / 0.5 / 0.75 / 1.0 percent stretch and a drivetrain speed, then answers replace now, monitor, or miles left from your wear rate. That is measured metal, not a vibe.

One tap logs a ride or bumps the odometer; miles roll onto whatever is fitted. Intervals can be miles or time. You can move a part to another bike and keep the history, or retire it to an archive and see cost-per-mile. Receipts, torque, notes sit in a log you own. Last they dated the listing, 26 May 2026, it was still TestFlight. Treat it as a workshop notebook you can try, not as a polished store app with a rating you can lean on. The privacy story is the product. The distribution story is still beta.

What Tiiks remembers

Tiiks reads the Strava ride you already published and puts those kilometers on the bike and on each fitted component. You name the part from a real catalog when we have it. Specs sit next to verified rider reviews that include mileage. The history stays with the bike when you service or replace. A Home Screen widget shows parts that already received the ride. We do not run a 0.75 percent stretch calculator, we do not live 100 percent offline, and we do not pretend a cloudless TestFlight is a flaw. They built a notebook you hold. We built a bike that already knows Saturday.

A checker reading versus a catalog name

Bikebook’s killer object is the stretch you measured. 0.5 is a different sentence from 1.0, and the app will say so, plus a miles-left guess from how fast you have been wearing chains. That is more honest than a generic “chain due” square. It is still not a catalog part with specs and a review at real kilometers. Tiiks names the chain. You can disagree with a rider; you can see how far they rode. A checker proves the metal in your hand. A review proves a metal other people already finished. You may want both. They are not the same drawer.

A ride you tap versus a ride that already exists

Bikebook updates parts when you log a ride or bump the odometer. No GPS, no network, no athlete connection. Miss a week and the notebook is only as true as your thumb. That is the privacy bargain, and they are clear about it. Tiiks reads Strava. The clerk job is gone. The parts move because you already recorded the ride somewhere you already live. If you refuse a social network on principle, their odometer is the point. If you already publish every commute, typing it again is a second job.

They win the lock. We win the identity.

No account, no subscription, no cloud, no analytics kit they admit to — Bikebook wins that column and should keep it. A finished native catalog cannot honestly claim “nothing leaves the phone” the same way. Tiiks wins the other column: a part that is a real object, reviews with mileage, twenty slots, a widget, iOS and Android, and the history of rides you already stored on Strava. Privacy is not a feature we are going to out-shout. Identity is not a feature a local notebook grows by adding a text field.

TestFlight and a browser tab versus a shipping store app

This comparison is uneven on purpose. Bikebook is a TestFlight beta and an in-browser log. It is not a finished App Store product with a public listing you can trust as done. Tiiks is a native iOS and Android app you can install as a product. Beta software can be the better notebook. It is still beta. If you need a store icon for a family member who will not join TestFlight, you already know which side of this sentence you are on. If you need a checker and a lock, their beta may be enough.

Who Bikebook is enough for

Stay on Bikebook if you wrench your own bikes, you want measured chain stretch, you will tap the ride yourself, and you refuse an account, a subscription, and a cloud — and you are willing to live in TestFlight or a browser on iOS 17. They win that rider, fairly. Choose Tiiks if you want the rides you already recorded to land on named catalog parts, with reviews, a service-or-replace history, a widget, and a finished native app on iOS and Android. An honest notebook is a good tool. It is not a catalog. Do not make it pretend.

Questions we get

Is Bikebook on the App Store?

Not as a finished public listing. Their own page presents a TestFlight beta and a browser app. iPhone, iOS 17 and newer. That is enough for a rider who likes betas. It is not the same object as a shipping store app. Tiiks is the shipping store app in this pair. If you only install from the store search bar, you will not find a completed Bikebook the way you find us — and we are not going to dress their beta up as one.

Does Bikebook connect to Strava?

No. That is the point of their design. Miles move when you log a ride or bump the odometer. Tiiks reads Strava and puts that distance on the bike and on each fitted component. If you wanted automatic wear without an athlete login, they have the notebook. If you wanted the file you already uploaded to do the work, we have the pipe.

Who wins if I care about privacy?

They do, on the terms they published: no account, no cloud, on-device, browser data that stays in the browser. Tiiks is a connected rider app. We are not going to invent a local-only mode we do not ship. If the lock is the whole job, use the notebook. If the named part and the rides you already recorded are the job, use us. You can hold both standards. You cannot get both from one icon.
