WhatsApp-Native Check-Ins
The WhatsApp check-in tool for coaches your clients will actually use
Your clients won't download another app. But they'll reply on WhatsApp in 30 seconds. NudgeCheck sends structured check-ins where your clients already are — and gives you back AI summaries and organized data.
The problem every coach knows
You start small. 5 clients, a few WhatsApp messages, everything manageable. Then you hit 15 clients and the system breaks. Messages lost in chat threads, forgotten replies, voice notes you never listen back to. You try an app — but half your clients won't download it, and the other half stops using it after a week.

How it works: from form to report in 4 steps
You set it up once, then NudgeCheck handles the rest.
1. Create the check-in form
Choose from rating scales, multiple choice, open text, and voice notes. Customize the intro message. 2 minutes, done.
2. Schedule delivery
Daily, weekly, or monthly. Pick the day and time. Assign the form to clients. NudgeCheck sends it automatically on WhatsApp.
3. Clients reply on WhatsApp
Clients receive questions on WhatsApp and reply with text or voice notes. Audio gets auto-transcribed by AI.
4. Get your AI summary
NudgeCheck generates a summary with risk flags, transcribes voice notes, and syncs everything to Google Sheets. Open the dashboard and you're caught up.

The numbers don't lie
Coaches who use WhatsApp-based tools see completion rates between 40% and 60%. Dedicated apps? Between 5% and 15%. Not because clients don't want to check in, but because they don't want to open another app.
WhatsApp has a 98% open rate. Email sits at 20%. When you send a check-in on WhatsApp, your client sees it. Period.
And the time saved? Coaches save 10+ hours per week on admin when they automate check-ins. Hours you can reinvest in actual coaching or growing your business.
