Frequently Asked Questions

TRAINIO is an AI-powered strength training app for Android and WearOS. It helps you track workouts, generate personalized training plans, and improve your form with real-time feedback.

Yes! TRAINIO is currently free during our beta period. All features are available at no cost. We plan to introduce a premium tier in the future, but core features will remain free.

TRAINIO runs on Android phones (Android 8.0+) and optionally connects to WearOS smartwatches for automatic rep counting and form feedback. iOS is not currently supported.

No. TRAINIO works great as a standalone phone app. However, connecting a WearOS smartwatch enables automatic rep counting and real-time form feedback features.

TRAINIO uses a simple Weight × Reps format (e.g., 80kg × 10 reps). This focused approach ensures accurate tracking and meaningful progress analysis for strength training.

TRAINIO is designed specifically for weight training. It does not support time-based exercises (like planks), distance-based activities (like running), or cardio metrics.

Currently, TRAINIO does not support importing workout data from other apps or CSV files. All workouts need to be logged directly in the app.

From the home screen, tap "Start Workout" and choose from: a scheduled program workout, a saved workout plan, AI-generated quick workout, or build one from scratch using the exercise library.

Tell the AI your goals, experience level, available equipment, and any limitations. It generates a personalized workout plan based on proven training principles tailored to your needs.

You can ask about training techniques, get exercise recommendations, request workout modifications, discuss your progress, and get general fitness advice. The AI coach knows your workout history and goals.

When using AI features, relevant workout data is sent to OpenAI to generate responses. We only send what's needed for your query. See our Privacy Policy for details.

Your WearOS watch uses motion sensors to detect exercise movements. AI models analyze the sensor data in real-time to count repetitions automatically during your sets.

Form feedback analyzes your movement patterns during exercises and provides audio cues (like "Slow down" or "Elbows in") to help you maintain proper technique.

TRAINIO supports WearOS smartwatches (Google Pixel Watch, Samsung Galaxy Watch with WearOS, etc.). The watch must be paired with your Android phone.

Yes. In the exercise details, you can enable or disable specific form checks per exercise. This lets you focus on the form cues most relevant to your training.

Your workout data is stored locally on your device and backed up to Firebase cloud storage. This allows you to recover your data if you switch devices.
