AHUs, VAVs, unit vents, plants and integrations, each with a how-to-test step and the response you should see.
0
pre-loaded functional tests across 11 equipment groups
Step 2 · Write it down
Opens fast on the old laptop in the truck. Excel, LibreOffice or Google Sheets.
Free iPhone app
Check points against typical tolerances (ASHRAE Guideline 13 for sensors), browse sequence tests, fix common faults and do field math. No account. No ads. No tracking.
Also inside: sample sequence tests, 11 fast fixes and field calculators. When the store opens, you can buy any kit in the app with your Apple account, or on this site with Apple Pay, your bank or a card. Either way, it unlocks all 93 tests in the app.
Phone + Windows · coming at launch
Panelside runs on iPhone, Android and Windows. Send the checks, notes and photos from your phone to the Windows app, then build the report on a full keyboard and screen.
Free · no account
Tap Send to Windows on your phone. Panelside makes one sync file you can move by OneDrive, Google Drive, iCloud Drive, email, USB or a quick QR pair on the same Wi-Fi. Open it in the Windows app and new checks merge in. Nothing already there gets overwritten.
Paid add-on
Sign in once on each device. Checks, notes, photos and signatures show up on your Windows PC seconds after you get signal. Everything is encrypted on your phone before it leaves, so we store only scrambled data and can't read your jobs.
Shown for demo purposes. Neither feature is available or for sale yet.

Try it before you buy
This works like the real file. Type a point name, pick its type and the test method fills in. Set a result and the summary updates.
All 21 point types. Tap one to see its test method and pass criteria.
% Complete = (Pass + N/A) / Total. Fail, Blocked and Untested rows still need work.
A 3-row preview. Rows start blank, like the real file, because untested results should never be pre-filled. The workbook has 500 point rows, 93 sequence tests and 555 live formulas.
Proof
These figures are counted from the file you download. We don't post reviews we can't verify, so you won't find invented ones here.
The preview above runs on the workbook's own Test Guide. Nothing to sign up for.

Security & privacy
Card and bank details are encrypted on your device and sent straight to a certified payment processor. We never see or store them. This website collects nothing about you.
Checkout pages load over HTTPS (TLS 1.2 or later). You type card and bank details into the processor's own hosted page, not ours.
Bank and card payments run on Stripe, a PCI Level 1 Service Provider that an independent assessor audits every year. Card payments can also run on Gumroad's hosted checkout.
Apple Pay sends a device-specific number and a one-time security code, approved with Face ID. Your actual card number is never shared with the seller.
No analytics, ad pixels or sign-up forms. Every script, font and image is served from this site, and a strict Content Security Policy blocks anything else.
Checks, photos and notes are saved on your iPhone and encrypted by iOS whenever it's locked. Backup goes only to your own private iCloud, which we can't read. Reports are built on the phone, with nothing uploaded. Optional Auto Sync encrypts everything on your phone before it leaves.
The app follows the App Review Guidelines and ships a privacy manifest. It's built against the OWASP mobile security standard (MASVS), and an independent security review comes before launch.
