1. Getting airborne: training and the free deployment

2. Controls: stick, tilt, nozzles and views

Stick or tilt

Fly with the on-screen stick, or tap Use tilt to steer with the phone's motion. iOS asks your permission the first time. Centre tilt in Settings sets the neutral position; Sensitivity adjusts the response. You can switch back to the stick during a flight.

Nozzles, gear and brakes

JET is conventional flight, STOL angles the nozzles for short take-off, and HOVER rotates them down for vertical flight. GEAR raises and lowers the undercarriage; the brake button is the wheel brake on the ground and the airbrake in the air.

Views and helpers

Switch between cockpit, chase, overhead and side views. Radar shows contacts, Landing view looks ahead on the approach, and Day and Night change the lighting where the sortie allows it. The Ground briefing in Settings repeats all of this inside the app.

Assisted flight

New pilots fly with wings-level assistance. TAKE CONTROL hands you the aircraft; LEVEL returns to assisted, wings-level flight if things get away from you. The Demanding setting in Settings tightens landing limits and arms an evasive drone; leave it off for the two-target combat lesson until you are comfortable.

3. Recovering to the deck

4. Spanner's Locker: buying and restoring

Everything optional is a one-time, non-consumable purchase. There are no subscriptions, currencies, random rewards or paid performance advantages, and your call sign is always free.

WhatContents
Highland AccordTen mountain and evacuation sorties, including two air-combat sorties.
Ember StraitTwelve desert and fleet sorties, including three air-combat sorties and two missile interceptions.
Ten cosmetic itemsThree aircraft paints, two pilot helmets, two nose markings, a cockpit badge set, a lucky fox and a brass nameplate. Each sold separately.
Original lockerCollection: Arctic, Midnight and Copper paints, the badge set and the lucky fox.
Pilot collectionCollection: Storm and Rescue helmets, Fox and Compass nose markings and the brass nameplate.

To buy

  1. From the opening menu, open Spanner's Locker. Deployments lists the free campaign and the two paid campaigns; Pilot locker holds the cosmetic previews, your call sign, the individual items and both collections.
  2. Preview first. Previews show what you get and never buy or equip anything.
  3. Tap the buy button, which shows the App Store price for your country. Apple's payment sheet completes the purchase.
  4. Campaign sorties appear in the mission grid immediately. Cosmetics must be equipped after purchase; helmets show on the pilot in exterior cockpit views, decals on the nose, paints on the airframe, and badges, the fox and nameplates in the cockpit.

If you already own every item in a collection the app will not sell you the collection again. A collection you partly own still costs its full displayed price, and the app tells you which items overlap before you buy.

To restore on a new phone or after reinstalling

  1. Sign the phone in to the same Apple Account that made the purchases and connect to the internet.
  2. Open Spanner's Locker and tap Restore purchases at the bottom of the shop.
  3. Owned content is unlocked again without a second payment. Re-equip cosmetics from the Pilot locker.

5. Progress and purchases are different

Your careerYour Apple purchases
Training passes, sortie results, qualifications, decorations, call sign, settings and equipped items. Saved in the app's settings storage on your iPhone, normally included in your device backup. Never sent to us. No cloud sync.Campaign packs, cosmetics and collections you have bought. Recorded by Apple against your Apple Account. Brought to another phone with Restore purchases.

Restoring purchases does not restore career progress, and a device backup does not restore purchases. Deleting the app removes its local save; if you want to keep a long career, make sure your iPhone backup is on before you delete or change phones.

6. Purchase unavailable, pending approval or refunds

"Currently unavailable" on a product

Apple has not returned the product to the app. Check that the phone is online and signed in to the App Store, then tap Refresh shop. The app never shows a made-up price; buy buttons stay disabled until Apple answers.

Ask to Buy and pending purchases

On a child's Apple Account with Ask to Buy, the purchase waits for the family organiser. Nothing unlocks and nothing is charged until Apple confirms approval. A declined request simply leaves the content locked.

Cancelled, failed or interrupted purchases

If you cancel Apple's sheet, the payment fails, or the app is interrupted mid-purchase, nothing unlocks and nothing is charged. Apple completes an interrupted transaction when it can, and the app picks it up on the next launch or when you tap Restore purchases.

Refunds and revoked purchases

If Apple refunds a purchase, that content locks again the next time the app learns of it. Career records you earned while you owned it are kept. A cosmetic you had equipped falls back to the free standard equipment, and an item stays owned if another purchase you still hold includes it.

7. Apple purchase and refund assistance

Apple processes every payment and decides refunds, so please use Apple's channels for refund requests:

If Apple asks you to contact the developer, email chris@patientthread.com. We can check how the app behaved, but we cannot see your payment details or issue App Store refunds ourselves.

8. Reporting a bug

Email chris@patientthread.com with the subject "Kestrel bug report" and as much of this as you can:

App version and build (shown on the opening menu, for example Version 0.12.0 · Build 36) Device model (for example iPhone 15 Pro) iOS version (Settings → General → About) The sortie or screen, and whether you were using stick or tilt Steps to reproduce, in order What happened, and what you expected instead A screenshot or screen recording if you have one

Never include your Apple Account password, verification codes or payment details. We aim to reply within two working days.

9. What Kestrel is, and is not

Kestrel is a fictional naval flight game: a made-up squadron, a fictional carrier and simplified flight and weapons models inspired by the jump-jet era. It is entertainment. It is not a flight-training product, not a simulation of any real aircraft or operation, and no real military organisation is involved or endorses it.

Read the Kestrel privacy policy for what the app does and does not do with your data.
