About this app

Your whole garage in your pocket. Save every bike, log every setting, and watch service intervals tick down as the hours and miles add up, so nothing sneaks up on you.

Service Assistant is the setup and maintenance logbook for people who work on their own bikes- dirt, street, ADV, or MTB. Add a motorcycle or mountain bike, save its baseline settings, then build a record you can trust instead of trying to remember what you changed three rides ago.

A SERVICE CENTER THAT COUNTS DOWN FOR YOU
Set the intervals that matter to you the most- suspension service every 40 hours, tune-up every 15 hours, chain every 300 miles. After a ride, log your hours or mileage once. Service Assistant subtracts from every interval automatically and tells you what's coming due before it becomes a problem. You can track by mileage or runtime depending on the bike type. Engine, suspension, chassis, brakes, electrical, drivetrain: if it runs on a schedule, you can track it here.

SETTINGS YOU CAN ACTUALLY FIND AGAIN
Save a baseline for every bike, then log what you change as you dial it in. Clicker positions, sag, spring rates, tire pressure, gearing, bar and lever position. Record it, compare it, and get back to it when a setup change doesn't pan out.

KEY FEATURES
• Unlimited bikes — a full profile for every machine you own or maintain
• Baseline settings — the known-good starting point you can always return to
• Setup notes — suspension, tire pressure, ergonomics, conditions, results
• Custom service intervals — by engine hours or mileage, set however you want
• Automatic countdown — add hours or miles once, every interval updates
• Complete service history — what you did, when you did it, on which bike
• Slacker Virtual Remote — turns your phone into a large, easy-to-read display for the Slacker digital sag scale

BUILT FOR RIDERS AND THE SHOPS THAT KEEP THEM RUNNING
Whether it's one bike in the garage or a rack of customer machines, everything lives in one place — searchable, organized, and there the next time you need it.

FROM THE MAKERS OF SLACKER
Service Assistant is built by Motool, the team behind the Slacker digital sag scale — the patented suspension setup tool trusted by riders, tuners, and shops since 2014.

Start with a 30-day free trial. $0.99/month or $9.99/year after that.


Payment will be charged to your Apple Account at the end of the 30-day free trial. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel your subscription anytime in your Apple Account settings. Any unused portion of a free trial is forfeited when you purchase a subscription.

I was having issue getting my Samsung s21 to connect to the slacker tool. I emailed customer support and had a response and solution within an hour. I ended up having to put my phone into airplane mode, restarting the phone, then turning off airplane mode. I initially planned on only using this app as a display, but found the setup and notes section to be well laid out and comprehensive.

This app used to be free. I paid for a product that had a free app. Now you're charging subscription fees. This is a money grab and unethical business practice. Response to the developer: I am not confusing the apps. I used to be able to use the Service Assistant app for free and store my sag measurements for multiple bikes. You now force me to pay for the same features that were advertised as included, at the time of purchase of the slacker tool.

You are confusing the app options. The Slacker Virtual Remote is still 100% free and it is everything you need to fully leverage Slacker. Service Assistant is not required to use Slacker and is a full featured app that has thousands of bikes to chose from and let's you save all your bikes, settings, setup notes, and service logs.

DONT BUY THIS TOOL OR SUBSCRIPTION! I really love the tool, but I just got an email stating there will now be a subscription fee to use "virtual assistant+" i.e. what is this app and the detailed tuning notes. Drop the subscription model and I will be absolutely happy to recommend this tool to anyone again. Let us save our tuning notes to our phone and drop the subscription model if cloud cost is the reason for switching. It really feels like a cash grab.

This app is not required to use the too. We offer the Slacker Virtual Remote app for free, and it does everything you need to use the too. This app has many more features and we are rolling out new features this month. Please download the Slacker Virtual Remote app, it is 100% free. This app is in no way required to use the tool.
