Why do I need to create an account?
Because "I don't know any better" is the most honest explanation of why you have to register an account. It's not because I'm interested in your email or your data.
WristLog is a web-based application, meaning it's running from my server, not your device. Why? I've been doing web applications for a very long time and I'm good at it.
The biggest pros of WristLog being a web application are that it hugely speeds up the development process for me, which is very critical for a spare-time project made by one person, and also makes it accessible from different devices and a web browser.
It has its cons too. Mainly, you have to have an internet connection to be able to use WristLog and have to register an account.
I tried to figure out a way so you don't have to register, or at least not know that you're creating an account and, most importantly, not have to provide your email. Unfortunately, I have achieved that for iOS only.
Is there a mobile app?
No, there isn't a native app.
There is! iOS app is available now.
Unfortunately there isn't Android app available.
There is! Android app is available now.
You can also add WristLog as a PWA (instructions ), which is very similar to a native app, on many devices, including iOS and Android phones.
How does accuracy tracking work?
First of all, WristLog cannot measure the accuracy of your watch. You need a timegrapher for that. WristLog uses your manually recorded points in time to calculate the accuracy of the watch. This means there's small human error involved. That being said, long term accuracy tracking is better for determining how your watch behaves in different positions and situations. You don't just measure a point in time as you do with a timegrapher, you discover patterns.
Each accuracy tracking starts with pressing a button when your watch precisely reaches a specific time. This is usually done when the second hand reaches the twelve o'clock position. At that point, WristLog compares the time on your watch with real time. If this is the first record, WristLog will use it as a baseline to determine how off your watch was from real time in the beginning. If there's a previous record, WristLog will calculate how the difference between real time and your watch time has changed since the last record.
Example
You record your baseline at 8 AM. Real time is 8:00:05, so your watch is already +5 seconds off. You add another record at 8 PM, but real time is already 8:00:10 at that moment. This means your watch has lost 5 seconds since the last record. Watch accuracy is usually measured in Seconds Per Day (SPD). Time elapsed between your two logs was 12 hours or 0.5 day. So between those two records, your watch was running at -10 SPD.
You can probably spot the main issue here already. Let's exaggerate a bit and say you pressed the log button 5 seconds later than your watch actually reached the time. This means WristLog thinks your watch was showing 8 PM sharp, but in reality, it was already 8:00:05. Updating the example above, WristLog would calculate your watch was running at 0 SPD instead of -10 SPD. You have to be very precise. It takes some practice, but at least for me, it's a fun activity to do! You also don't want to record accuracy too often. A small window between records means that even the tiniest imperfection in your logging can greatly distort the result.
Why record the accuracy of my watch?
Subjectively, it's a fun little activity. You get to spend some focused time with your watch and enjoy the results as they come in. More practically, you can see potential issues with your watch's movement. Is it way off the specification? It might be time to service your watch.
For quartz, solar, or digital watches, tracking once a week or month is sufficient. These are highly accurate compared to mechanical movements, so frequent recordings amplify small human timing errors.
How does timegrapher work?
Technically the same as a real timegrapher. It listens to your watch ticking. You firmly press your phone's microphone against the watch and let it measure for a few seconds until the signal stabilizes.
Obviously, the microphone on your phone cannot produce results as precise as a professional grade timegrapher does. But it's already in your pocket and you don't have to spend hundreds of dollars for it. And the results are pretty good! Especially for watches that tick louder. Combined with accuracy logging, you should be able to determine how the movement of your watch runs and how it behaves.
You have to be in a very quiet environment for timegrapher to provide decent results!
How does wrist time tracking work?
This part is really simple. You just log a Wristcheck if you wear a specific watch. In the long term, you can see how much wrist time your watches get. Pssst, you can even sell watches you don't wear that much!
Who are you?
Adam, hi! Here, I'm just a watch nerd. I made WristLog for myself and decided to share it with the world. I'm also a developer, father of two kids, and I like cars.
