About
Hi, I'm Jakub — an independent iOS developer building AI-powered apps. I started because I couldn't find tools that actually fit my lifestyle: a keto tracker that doesn't make me search through a food database for every meal, a workout planner that works with my home gym equipment, a mushroom identifier I can trust in the field, and a sun tracker that tells me exactly when to go outside for vitamin D.
KetoSnap uses Google Gemini AI to analyze photos of your meals and give you net carbs, macros, and a keto score from 1-10 — no manual food logging required. Plates generates custom lifting programs based on your actual equipment and schedule, tracks progressive overload, and tells you when to increase weight. Nova Fast tracks your intermittent fasts with real-time biological phase monitoring — see when you enter ketosis, autophagy, and deep cellular repair, with widgets, water tracking, and XP gamification. Mushroom Hunter identifies mushrooms from a photo with safety alerts, toxic look-alikes, a foraging journal, and a private map for your best spots. RayDay calculates your daily vitamin D window using NOAA solar algorithms and tracks IU production in real-time — personalized for your skin type, clothing, SPF, and weather.
I build these apps in the open and love hearing feedback. If you have a feature request or just want to say hi, reach me on X (@jakublaszczyk) or email support@jakubl.com.
