What is Crispr?

Crispr is a calm cookbook for the air fryer you already own. Open it, pick what you are making, and a multi-step timer walks you through preheat, flip and finish on the Lock Screen and in the Dynamic Island, so you can prep the rest of dinner without staring at your phone.

A bundled time and temperature chart answers the question you actually have at 6pm: how long and how hot for chicken thighs, salmon, brussels sprouts, frozen fries. One tap switches Celsius or Fahrenheit, grams or ounces.

There is no account, no login and no email capture. Every recipe is on your device from the first install, everything works fully offline, and nothing is uploaded anywhere.

Frequently Asked Questions

How long do you cook chicken in an air fryer?

Boneless chicken thighs typically take around 18–22 minutes at about 380°F (193°C), while breasts often need slightly less time; thickness matters more than weight. The reliable check is internal temperature — chicken is done at 165°F (74°C). Crispr's built-in time and temperature chart lists common cuts with suggested times and temperatures, and the multi-step timer reminds you when to flip.

What temperature should an air fryer be for frozen fries?

Most frozen fries cook well at around 400°F (200°C) for 12–18 minutes, shaken or flipped halfway through. Thicker cuts need the longer end of that range. Crispr keeps these numbers in an offline chart, so the answer is there even if your kitchen has no signal.

Is there an air fryer app that works offline?

Yes. Crispr ships every recipe and the full time-and-temperature chart on the device, so nothing requires an internet connection. You can look up cook times, run the multi-step timer and save favorites in airplane mode. Nothing is uploaded anywhere.

Is there an air fryer recipe app without an account or login?

Crispr never asks you to create an account, log in or hand over an email address. Your favorites and settings are stored on your iPhone. That also means there is nothing to sync, break or leak.

Can my iPhone show a cooking timer on the Lock Screen?

Yes — iPhones support Live Activities, which keep a timer visible on the Lock Screen and in the Dynamic Island. Crispr uses this for its cook timer, so preheat, flip and finish steps are readable at a glance without unlocking the phone. It is built for hands-busy cooking.

What is a multi-step cook timer?

Instead of one countdown, a multi-step timer chains the stages of a cook: preheat the basket, cook the first side, flip, then finish. Each stage has its own alert, so you act at the right moment instead of doing mental math. Crispr sets these stages automatically from the recipe you pick.

How do I convert air fryer temperatures between Celsius and Fahrenheit?

A quick rule of thumb: 180°C is about 350°F, 200°C is about 400°F. Rather than converting by hand mid-cook, Crispr's chart and recipes switch between Celsius and Fahrenheit — and grams and ounces — with one tap.

When should I flip food in an air fryer?

Most foods brown more evenly if flipped or shaken roughly halfway through the cook — fries, wings and vegetables especially. Some delicate items like salmon fillets can skip the flip. Crispr's timer builds the flip step into each recipe and alerts you when it is time.

Does Crispr work with any air fryer brand?

Yes. The recipes and chart use standard times and temperatures that apply to basket and oven-style air fryers alike, whatever the brand. Since models vary a little in power, treat the first cook as a calibration and adjust a minute or two either way.

Can I cook frozen food straight in an air fryer?

Yes — frozen fries, nuggets, wings and many vegetables go straight from freezer to basket with no thawing. They usually need a slightly longer time than fresh, and a shake halfway helps. Crispr's chart includes frozen staples with suggested times and temperatures.

Can I print recipes from an air fryer app?

Crispr exports any recipe as a clean PDF card that you can print or share from the standard iOS share sheet. It is handy for sticking a family favorite on the fridge or sending a recipe to someone without the app.

Why does my air fryer food come out soggy?

The usual causes are an overcrowded basket, skipping the preheat, or too low a temperature — steam needs room to escape for food to crisp. Cook in a single layer and shake or flip partway through. Crispr's recipes include a preheat step in the timer so that part is never skipped.

Does the app track what I cook or collect data?

No. Crispr has no account system, no email capture and no upload of any kind. Favorites and history stay on your device, and the app is fully usable offline.
