Nutritionist software with WhatsApp: weekly check-ins without making patients download an app
As a nutritionist, follow-up is everything. You know the meal plan only works if the patient actually follows it — and to know that, you need to ask. But between appointments, how do you actually monitor adherence? WhatsApp is the natural channel, but messages get lost, responses are fragmented, and those 4-minute voice notes sit in your phone without being properly analyzed.
The nutritionist-specific problem
Unlike a personal trainer, a nutritionist needs detailed qualitative information: how the patient feels, whether they experienced hunger between meals, gastrointestinal issues, sleep quality, cravings. This information often arrives as long voice notes — rich in detail but impossible to organize.
- ✗3-5 minute voice notes: valuable information but impossible to archive
- ✗Scattered chat responses: no structured history
- ✗Manual follow-ups: you forget to ask, or the patient forgets to respond
- ✗Dedicated apps: the patient has to download something, and half don't
NudgeCheck: structured nutrition check-ins, directly on WhatsApp
NudgeCheck is built for nutrition professionals who want systematic follow-up without forcing patients onto new platforms. Here's how it works: create a weekly check-in questionnaire with the questions you need, schedule it for your patients, and NudgeCheck sends it on WhatsApp automatically. Patients respond in the chat — voice notes included.
Automatic voice note transcription
Patient sends a 4-minute voice note about their week? NudgeCheck transcribes it automatically. You get the full text without replaying anything.
AI summary with key insights
AI analyzes responses and generates a summary: overall adherence, reported difficulties, signals to investigate further. In 30 seconds you have the full picture.
Customizable questions
Ask what you need: plan adherence, hunger between meals, hydration, sleep quality, energy levels, GI symptoms. The questionnaire is yours.
Google Sheets sync
All responses sync automatically to a Google Sheet. You have a complete history of each patient, week by week.
NudgeCheck vs. NutriTec: honest comparison
NutriTec is the only other tool with WhatsApp integration for nutritionists. But it has a different focus: general communication automation (appointment reminders, recipe delivery, personalized messaging). NudgeCheck specializes in structured check-ins — the follow-up piece that makes the difference between a meal plan that works and one that gets abandoned after two weeks.

What your patients see
For the patient, the experience is identical to a normal WhatsApp conversation. They receive a message with the weekly check-in, answer the questions one by one, and that's it. No downloads, no sign-ups, no passwords to remember.
This makes a huge difference in response rates. With dedicated apps, check-in completion rates drop after the first few weeks. On WhatsApp, where your patients already spend their time, response rates stay high long-term.
Use case: weekly nutrition check-in
A nutritionist with 25 patients sets up a weekly check-in with these questions:
- How would you rate your adherence to the meal plan this week? (1-10)
- Did you experience intense hunger between meals?
- How would you describe your energy throughout the day?
- Did you notice any GI symptoms (bloating, heaviness, etc.)?
- Is there anything else you'd like to tell me about your week?
Every Friday at 6 PM, all 25 patients receive the check-in on WhatsApp. They respond over the weekend. Monday morning, the nutritionist opens the dashboard and has 25 AI summaries ready, with key points already highlighted. Total time: 15 minutes for review instead of 3+ hours.
Who NudgeCheck is for
- Nutritionists and dietitians with 10-50 patients in follow-up
- Nutrition professionals working in-clinic and online
- Professionals already using WhatsApp to communicate with patients
- Those wanting to improve meal plan adherence rates
