Almost none of them started with the weather.
They started with the pilot wanting it to say yes.

Same airfield. Same minima. The weather is the only thing that moves.

Cold start, calm air
This is not a weather app. It is a contract with yourself.
Five surfaces. One verdict against the line you drew when you were honest. Read it before you’ve talked yourself into anything.
01 . Widgets
Glance before you’ve decided.
The pill on your Lock Screen reads the latest METAR, TAF and amendment against your active minima. You see the answer before you’ve started rationalising.
02 . Always watching
It checks the TAF amendment. You won’t have to.
METAR every 30 min. AMD and SPECI the moment they post. The pill flips if any of them moves the line. One push. One.
Active preset
03 . Presets
Solo, Dual, XC. Different days, different lines.
Each preset is its own minima. The verdict runs against the one you’re flying under today, not the bolder one you wrote last summer.
Minima . Solo
04 . Personal minima
The line you drew when you were honest. Held when you’re not.
Five metrics. Four presets. A drift detector watches the months you quietly raise your wind ceiling 2 kt at a time.

Show me. Don’t tell me.
Tap any verdict. Raw METAR. Raw TAF. The exact rule that fired. BECMG and FM drive the answer. TEMPO and PROB never silently flip it.
Every verdict has a footnote.
Eight signals. Watched every refresh. Cross-checked against the minima you set, not the ones you might set in twenty minutes.

You can reproduce every verdict by hand with the METAR open. That is the contract. Threshold is a watchdog. It is not your flight planning.
“All through my PPL I kept personal minima in a Notes file. The maths was never the hard part. Being honest about it was. So I built something that runs the check before I want to.”
Trusted by 729+ pilots across the UK and EU.
“I’d checked the METAR before turning in. A TAF amendment posted overnight. The pill caught it. I didn’t. Saved me a 90-minute drive into a NO.”
“The drift detector caught me. I’d quietly bumped my wind ceiling from 18 to 22 kt over two months. I wasn’t honest enough to admit it. The app was.”
“I’d planned the night before. While I was on the motorway the wind shifted onto 23 and pushed crosswind 2 kt over my IR limit. The pill flipped before I noticed the direction change.”
“Eight hours from my skills test, the TAF flipped overnight. Threshold caught it before my instructor messaged. Felt like having a quiet senior pilot in my pocket.”
“My students set their own minima now. We talk about them on the ground. The drift detector means I see when they’ve quietly relaxed a limit. Best teaching tool I’ve added in years.”
“Touring with my partner, six days planned. Threshold flipped GO to HOLD on day three before we even got to the aircraft. That was the right call we wouldn’t have made calmly ourselves.”
“Saturday morning. METAR clean, TAF said BECMG with gusts to 28. Five tabs deep before Threshold flipped to HOLD on the Lock Screen. Saved me a 90 km drive to find out the hard way.”
“My strip doesn’t get METARs. Threshold reads the nearest within 15 NM and tells me when it’s interpolating. That honesty is the bit other apps skip.”
“Atlantic weather flips fast. The Live Activity is the bit I didn’t know I needed. Mid-drive, the screen lights up: HOLD at Weston. I turned the car around.”
“Forty hours in. My CFI showed me Threshold on his phone. I set my own minima tighter than his. The app didn’t argue.”
Before the slot. Before the drive. Have the answer ready.
