Keto sounds simple until you actually do it. Macros need to hit a specific ratio (typically 70% fat / 25% protein / 5% carbs), one wrong sauce can blow your daily carb budget, and most “keto-friendly” products contain sneaky carbs.
Swoodie is built around AI nutrition tracking that catches what manual logging misses. Photo-scan your plate to estimate net carbs, scan a barcode to verify a packaged product, and ask Chef AI to convert any recipe into a keto-compliant version.
What keto eaters struggle with
- Hitting the carb ceiling exactly (under 20g net carbs/day is unforgiving)
- Hidden sugar and starch in sauces, dressings, and processed ‘keto-friendly’ products
- Recipe boredom — keto cuts out a lot of options
- Cooking for non-keto partners or family
- Tracking macros without a kitchen scale at every meal

AI photo carb tracking
Snap a plate, see carbs, fiber, fat, and protein. Catches the rice you didn’t mean to eyeball.
Blood Sugar Score on every scan
A scanned meal comes back steady, moderate or spiky — estimated from its carbs and fibre — which is the quickest way to spot a “keto-friendly” product that doesn’t behave like one. An estimate and a tracking signal, not a medical reading. Uses your free AI tries on Free and Lite; unlimited with Premium.
Smart Swaps for a spiky meal
If a meal lands spiky, swap in a steadier version of the same dish with one tap instead of rebuilding it yourself. Premium.
Product Check — packaged-product quality score
Scan any packaged product's barcode for an instant 0–100 quality score and see the additives and labels behind it, so you can compare options at a glance. Free scan + score; better alternatives take Lite or Premium, and Ask AI is Premium.
Coach Ollie’s daily insight
One short observation drawn from what you actually logged, not a generic keto tip — useful on the days the carb ceiling got away from you. Free; deeper pattern-spotting is Premium.

Load the curated 7-day Keto plan into your planner, then tweak any day to taste — your low-carb week is built in seconds.

It depends on your priority, but for keto and low-carb the best app is one that does more than count calories — it should also plan meals and suggest recipes.

Is there an app made specifically for keto and low-carb?

Can one app do both calorie tracking and recipes?
Yes — that combination is exactly what Swoodie is built for. Most apps pick a side: calorie counters track but do not help you cook, recipe apps cook but do not track. Swoodie does both — AI photo and barcode scanning feed a daily calorie dashboard, while AI recipe generation and a meal planner handle what to actually cook.
