GenReadyGenerator maintenance log

GenReady is a generator maintenance log for home generator owners, built for any brand of standby, portable, or inverter generator. You enter engine hours, and each service item, from the oil change to the spark plug, counts down by hours or months, whichever comes first. Before hurricane season a pre-season checklist fills a readiness gauge, and finishing it stamps that year's season-ready badge. Records stay on the phone and the app needs no connection, which matters most in the middle of an outage.

Three moments

01

Finish the pre-season check, earn the badge

The pre-season checklist covers the start test, oil, air filter, spark plug, battery, fuel, CO alarms, and storage. Each check is dated and moves the readiness gauge a step. Check the last item and that year's season-ready badge is stamped, with one plain line underneath: it records your checks and does not guarantee the generator is safe or will run.

02

Log engine hours and see what is due next

Type the reading from the hour meter, or log a start test in minutes. Oil, air filter, and spark plug each count down by hours or months, whichever comes first, and the list puts whatever is due soonest at the top. No hour meter? Leave hours unknown and the schedule runs on months.

03

Know how old the fuel in the tank is

Log each fill with the date, the fuel type, and whether you added stabilizer. A storage-age bar shows how long that gasoline or diesel has been sitting and suggests a check as it ages. Propane has no age clock, so a propane setup gets a cylinder check card instead.

The service history usually lives on a scrap of paper

Ask a generator owner when the oil was last changed and the answer is often a guess, a date written in marker on the shroud, or a receipt somewhere in a kitchen drawer. The machine sits for months, runs hard for three days after a storm, and then sits again. That rhythm is exactly what makes it hard to remember what was done, and when.

Some generator makers offer apps that monitor their own connected models remotely. That is a different job. Plenty of generators in garages and side yards have no connectivity at all, and a monitoring screen is not a service log. GenReady is the log: any brand, any model, typed in by the person who did the work.

Hours or months, whichever comes first

Owner's manuals schedule service two ways at once. Honda's manual for the EU2200i, for example, lists an oil change every 6 months or 100 hours, whichever comes first, so a generator that barely runs still gets fresh oil and one that runs through a long outage gets it sooner. GenReady applies the same rule to every item it tracks.

When you add your generator you pick its type, standby, portable, or inverter, and either a preset for a popular model or a custom model. A preset is only a starting point drawn from published manual practice, and every interval can be changed to match your own manual. The schedule screen says it plainly: your owner's manual comes first.

A service record takes a couple of taps: the item, the date, the engine hours at the time, and if you want them, the cost, a note, and a photo of the receipt. Any record can be edited or deleted later, and the due list recalculates when you do. If a new hour reading is lower than the last one, say after a meter swap, the app asks before saving it instead of refusing.

The pre-season check, one item at a time

In hurricane mode the season follows the National Hurricane Center's dates for the Atlantic, June 1 to November 30. Ahead of each season the checklist resets for the new year, and if reminders are on, one tells you it is time to start. You do not have to finish in a single Saturday. Each item records the day you checked it, with an optional note, and the gauge holds its place between sessions.

The readiness gauge lights its first segment the moment you add a generator, and the first check moves it visibly, so the app is just as useful in January as it is in May. When the last item is checked, the badge for that season is stamped once, with a short haptic tap. The next year the list resets and there is a new badge to earn.

Checks can be undone and dates corrected. Unfinished items show as what is left, such as three items remaining, without red warnings or streak counters. A service that slipped is a normal state for a machine that sits most of the year.

Built for the day the power is out

GenReady makes no network requests and has no account. Everything is stored on the phone, so the log, the checklist, and the fuel dates open the same way when the cell network is down and the house is dark. There is no analytics SDK in the app.

Reminders are optional and arrive as a short weekly digest rather than a ping for every item, with neutral wording that keeps your generator's name, your address, and costs off the lock screen. A JSON backup can be exported through the share sheet and restored on a new phone, and Settings has a single option to delete all data.

Not on the hurricane coast

Where the grid goes down on a schedule rather than with the weather, a hurricane season means little. Load shedding mode keeps the checklist year-round and resets it on a cycle instead of once a year, and the gauge is labeled for year-round readiness. A general mode works the same way with neutral wording. The mode is a setting, and you can switch it at any time.

What it leaves out on purpose

There is no Bluetooth, Wi-Fi pairing, or remote monitoring, and no parts store, wattage calculator, or serial-number lookup. GenReady does not teach installation or repair. The checklist records that you checked something, not how to do it; your owner's manual and a qualified technician cover that part.

Frequently asked questions

Does GenReady connect to my generator?

No. There is no Bluetooth, Wi-Fi, or telemetry. You type the engine hours from the meter, or log a start test, and the schedule works from that. It is also why the app works with any brand, including generators with no electronics at all.

Which generators does it work with?

Any home standby, portable, or inverter generator. Presets cover a handful of popular models, and a custom model works exactly the same way. Brand names in presets are labels only; GenReady is not affiliated with Generac, Honda, or any other generator maker.

What if my generator has no hour meter?

Choose unknown when you add it. Items then come due by months alone, and start tests can still be logged as usual.

How often should I change the oil in my generator?

Follow your owner's manual, because schedules differ by engine. Honda's EU2200i manual lists every 6 months or 100 hours after the first change, and Generac's support guide for home standby units lists every 200 hours, or at least every 2 years. GenReady lets you set the interval your manual gives and tracks both limits.

Does a season-ready badge mean my generator will work in a storm?

No. The badge shows that you logged every item on the checklist. It is not an inspection, and it does not guarantee safety or that the engine will start. The app shows that line on every gauge and badge.

Where is my data stored, and can I move it to a new phone?

On your phone only. There is no account and nothing is uploaded. Export a JSON backup and restore it on the new phone, or delete all data from Settings in one step.
