That's 82g protein today — 18g short. A Greek yogurt tonight closes it. Nice day overall.

Nudges that know your life.
Your coach remembers you skip breakfast Mondays, snack when stressed, and crush protein on leg day. It coaches you. Not a generic avatar.

You under-eat on Wednesdays (avg 1,050 kcal). Want me to send lunch ideas the night before?
9:15
yes pls 🙏

Done. I'll nudge you Tuesday night.

It doesn't wait for you to open it.
Tracking apps go quiet the moment you do. Sunn keeps the conversation going — a check-in in the morning, your meals as they happen, and the day closed out at night.

Built for the messy middle —
not the honeymoon phase.
A coach that actually knows you.
Every other diet app starts from zero every session. Sunn remembers preferences, patterns, and goals. The more you chat, the sharper it gets.

05 · Sunn vs. the diet-app graveyard
Tired of apps that don't stick?
We built Sunn after trying — and abandoning — every diet app on the market. Here's why this one's different.
Logging dinner in a tracking app
- 1Open the app. Dismiss the streak popup.
- 2Search “salmon pasta”. Scroll 212 results.
- 3Guess the grams. Adjust the serving. Save.
- 4Repeat for the salad. And the dressing.
~4 minutes. Every meal.
Logging dinner with Sunn
- 1Send a photo of your plate.
- 2That's it. Calories and macros come back to you.
~5 seconds.
And because it's this easy, you still do it in week six — which is the whole game.

06 · Why this exists
“I've downloaded MyFitnessPal four times. The problem was never motivation — it was that logging dinner felt like filing taxes. So I built the tracker I could actually live with: you text a photo, it does the rest, and it remembers you tomorrow.”
Espen, founder of Sunn

Questions
Stuff people ask all the time.
Will my friends see Sunn messages in my WhatsApp?
No. Sunn is a private one-on-one chat with our verified Business account. It shows up in your chat list only, the same way a chat with any one friend would. It never posts to groups, never appears in a friend's chat history, and we don't touch any of your other conversations.
What happens when my 7 days are up?
Your plan starts automatically at the price you picked ($6.67/mo billed yearly, or $14.99/mo monthly). You can cancel any time before the trial ends by sending "cancel" in the chat. No forms, no phone call, no fine print.
What if I don't lose weight?
Message us within 30 days of your first payment and we'll refund you in full, no questions asked. If Sunn isn't the first tracker that actually stuck for you, we haven't earned the money.
Does it connect to Apple Health, Fitbit, or Oura?
Apple Health sync is in beta for iOS (join the waitlist in-chat). Fitbit and Oura are on the near roadmap. Today, you can tell Sunn your steps or training load in chat and it'll factor them into your daily target, same result, zero setup.
Wait, it's really just WhatsApp?
Yes. No app to download, no new password, no new icon on your home screen. If you can text a friend, you can use Sunn. We also have a web chat if you prefer desktop.
How accurate is photo tracking?
Accurate to within 10 to 15% for most foods. On par with a careful manual entry and much faster. When something's ambiguous ("small or large fries?"), Sunn asks. You can always tap "edit" and correct it in one line.
Will it judge me?
No. Sunn is trained to be direct and kind, never preachy. Logged a pint of ice cream? "Noted. Want a protein-heavy breakfast tomorrow?" That's it.
How is this different from MyFitnessPal or Noom?
MyFitnessPal is a food database. Noom is a CBT course. Sunn is a coach that lives in your pocket, learns your patterns, and replies in seconds. No database to search. No modules to finish.
Is my data private?
Yes. Everything is end-to-end encrypted. We don't sell or share data. You can export or delete everything with a single tap. GDPR and HIPAA-grade infrastructure.
Can I cancel anytime?
Yes, with one tap in-chat. No forms, no "talk to an agent," no fine print. Your 7-day free trial starts as soon as you sign up, and you can cancel any time before it ends.
