Support
One person answers this inbox. You'll get a human, not a ticket bot.
Usually answered within two working days. Same address for privacy questions, a copy of your data, or deleting your account — put what you need in the subject line and it'll get there.
Include these and it'll be sorted in one reply: your iPhone model and iOS version, what you tapped, what happened, and a screenshot if the screen said something odd.
The shutter button won't press
That's the scale reference. The app won't take a photo it can't measure, so the shutter stays disabled until it can see a coin.
- Put the coin flat on the plate, beside the bead — not on top of it, not standing up, not half out of frame.
- Check which coin the app is looking for: Settings → Scale reference. It never guesses which coin you used, because a US quarter and a UK 10p are within 1% of each other and picking the wrong one would quietly rescale every measurement.
- The 12-sided UK £1 and the Canadian loonie aren't supported — they fail the roundness check. Use a 10p, a 2p, a £2, a quarter, a €1, a Canadian quarter or an AU $1.
- Spatter and heavy scale on the coin can hide its edge. A clean coin reads better.
It says the photo is too blurry, too dark, or has too much glare
The app checks the shot before it spends a scan on it. Each message names the fix:
- Too blurry — brace your elbow on the bench or the workpiece and take it again. Phone cameras hunt for focus on dark metal.
- Too much glare — angle away from the overhead light, or shade the bead with your body. A hot white streak across the bead hides exactly the toe detail the score depends on.
- Too dark — more light, closer light. A phone torch held off to one side usually beats direct overhead light.
Let the plate cool a little too. Heat shimmer above a hot bead reads as blur.
It scanned, then said it couldn't assess the weld reliably
That's the model looking at your photo and declining, rather than inventing a number. The screen names the reason — usually image quality, a missing or ambiguous scale reference, or something that isn't a weld bead.
A refusal never uses one of your free scans. Retake the photo and try again. The app deliberately won't re-score the same refused image, because sending identical pixels back gets an identical answer.
A weld in my log hasn't been scored
Open the weld and look at the status on the detail screen. There are three different causes and they need different things:
- "Sign in to score this one" — scoring needs an account. Go to Settings → Account → Sign in. Anything you captured while signed out is picked up and scored automatically once you're in. Nothing is lost in the meantime.
- Waiting on a connection — it's saved on your phone and will score itself when you're back on a signal. You don't have to do anything.
- It tried and failed — tap Score this one on the weld detail screen. Automatic retries stop after three attempts so a stuck weld can't keep hammering away in the background, but the manual button has no such limit.
An old weld shows "photo isn't on this phone anymore"
The image file is gone from local storage — usually a cleared cache, a reinstall, or a weld restored to a new phone from your account. The score, the defect list and the coaching all survive; only the picture is missing. There's nothing to fix, and nothing else was lost.
Subscriptions, trials and restoring a purchase
- Restore a purchase — Settings → Restore purchases, or the same button on the paywall. Use the Apple ID you bought it with.
- Cancel — iPhone Settings → your name → Subscriptions. Cancelling is Apple's, not ours; we can't do it for you and don't need to be told.
- Refunds are handled by Apple at reportaproblem.apple.com. We never see your card details.
- Free scans — three completed scores per calendar month, reset on the 1st. Refused photos don't count against them.
Deleting things
- One weld — swipe it away in your log. Its photo and analysis go from our storage too.
- Everything — in the app, You → Delete my account. Account, welds, photos and settings go from the phone and from our servers. There's no undo and we can't recover it for you. Email stedeveloper1@gmail.com if you'd rather we did it.
- A copy of your data — same address, and we'll send it.
The leaderboard
It's off until you switch it on. To leave, turn it off in Settings — you disappear immediately, because the board is generated live from your current setting and there's no cached copy holding your name.
To report a display name that's offensive or impersonating someone, use the report control on the leaderboard itself. Reports come to us, not to the person reported.
You scored my weld wrong
Tell us. Every result has a "this call was wrong" link, and it's the most useful thing you can send — you're stood in front of the bead and we're looking at a photograph of it. Corrections go straight into improving the scoring.
What we can't help with: whether a weld is safe to use. Not for a hitch, a lifting eye, racking, a roll cage, a pressure vessel, or anything that ends up over a person. That needs a Certified Welding Inspector and, usually, RT or UT. It isn't that we won't say — it's that a photograph genuinely cannot answer it.
Other things people ask
What do I need to run it?
An iPhone on iOS 17 or later. It's an iPhone app — no iPad build, and no Android version yet.
Can I use it without signing in?
You can use the log entirely on-device by choosing "keep everything on this phone" at sign-in. Scoring needs an account, and you can create one later from Settings → Account without losing anything you've already captured.
Does it work in my country?
Yes, as long as one of the supported coins is to hand: US quarter, UK 10p, UK 2p, UK £2, €1, Canadian quarter or AU $1. Missing a coin from your country? Email us with which one — adding a verified diameter is a small change.
Can my class or shop use it?
Yes, and if you teach welding we'd like to hear from you — particularly if you're a CWI or an assessor willing to look at our scoring rubric. Email stedeveloper1@gmail.com.
What are you working on next?
Aluminium, stainless, pipe, and the vertical and overhead positions — all on the waitlist in Settings, and the waitlist is genuinely what we work from. We'd rather score a narrow set properly than guess at everything.
