The meal
Log normal meals.
Use photo, voice, or text. AI drafts the meal. Fix it like you’d say it — “only ate half the sauce” — and the numbers redo themselves.
AI food tracker for energy, calories, and meal patterns
Make every meal fuel your day.
Food should fuel you, not flatten you. Log normal meals with photo, voice, or text, check energy after eating, and see what seems to drain, steady, or fuel your day.
No card. No automatic bill.
Start with a full-access week: log real meals, check energy, spot private patterns, and test one Next Plate idea. No card. No automatic bill.
Riveryn is live on the App Store for iPhone. Install it from Apple, then use the full app for 7 days with no card required.
01 · The problem
Your energy has receipts.
Some meals leave you steady. Others leave you foggy, heavy, hungry, or reaching for another coffee. Your food log should explain the day, not just count the meal — Riveryn helps you check energy after eating and see what seems to drain, steady, or fuel your day.
02 · How it works
Log the meal. Check the energy. Test the next plate.
No food homework. Photo, voice, and text logging make full-day tracking fast enough for real life — and corrections work like talking, not data entry.
The energy
Check energy after eating.
One tap: low, sluggish, steady, or great. Every read lands on your day graph — and by the end of a normal week, the line starts to explain your days.
The next plate
Test the next plate.
See what seems to repeat, then try one simple change at the next meal. Save what works and relog it in one tap.
Most photo calorie apps stop at the estimate. Riveryn keeps going.
03 · Fuel clues
Small patterns. Practical next steps.
Fuel clues are small patterns between meals and energy. Riveryn helps you notice repeatable clues and test one change at the next meal.
-
Low after lunch?
Test a smaller portion or a lighter plate next, then check whether the afternoon feels steadier.
-
Hungry an hour later?
Look for missing protein, fiber, or enough total food before you blame willpower.
-
Steady twice?
Save the meal and relog it in one tap. Repeat what works.
04 · How it helps
Riveryn helps you see what changes the day.
The estimate is only the start. Riveryn connects the meal, day context, energy reads on the graph, plan-aware judgment, ranked factors, and one Next Plate cue so your food log helps the meal that comes next.
- Photo, voice, or text meal logging
- Plain-words corrections: say “only ate half the sauce” and the numbers redo themselves
- Energy reads — morning, after meals, evening — on your day graph
- Plan-aware callouts: a small overage on a plan-fitting day reads “right on cue,” not a red alarm
- Top suspects: your energy factors, ranked
- Next Plate cues to test
- Saved meals that relog in one tap
05 · The next plate
Eat for the life after the meal.
One meal is a clue. A few normal days can show what seems to drain, steady, or fire up your day. Your next plate becomes the next experiment.
- Food should fuel you, not flatten you.
- Slow morning? Test an earlier, lighter dinner.
- Flat by late afternoon? See where caffeine and sugar rank in your suspects.
- Bright after a familiar meal? Save it and repeat it.
- Your next plate becomes the next experiment.
06 · Private by design
Private. Honest. No shame.
- No required account for the core app.
- No ads or ad tracking.
- Photos, notes, and voice are used for the meal checks you request.
- Energy check-ins are optional.
- Wrong estimate? Fix it in plain words.
- Export or delete local data.
- Not medical advice.

10 · FAQ
Plain answers before you try it.
Is Riveryn a calorie tracker?
Yes. Riveryn estimates calories and macros on every meal — and the main job is connecting normal meals, portions, timing, and balance to energy so you can see what seems to drain, steady, or fuel your day.
How does Riveryn know my energy?
Riveryn learns your energy from check-ins you add with one tap — morning, after meals, or evening. Low, sluggish, steady, great, or skipped all count, and every read lands on your day graph. Over 2-3 normal days, those check-ins can reveal simple patterns based on your own meal history. No check-in, no guess: Riveryn only knows what you report.
What makes Riveryn different from photo calorie apps?
Most photo calorie apps stop at the estimate. Riveryn keeps the loop going: meal, plain-words corrections, day context, energy reads on the day graph, plan-aware judgment, your factors ranked, and a practical Next Plate cue.
What happens after the 7 days?
The full-access week ends without automatic billing. If Riveryn helped, you can choose Premium through Apple. Apple shows the current price, billing period, renewal terms, and cancellation path before purchase.
Is this medical advice?
No. Riveryn is for general nutrition awareness and meal planning. It is not medical advice, diagnosis, or treatment.
Are the nutrition estimates exact?
No. Food tracking estimates are approximate, especially for portions, restaurant meals, and mixed dishes. That is why corrections are plain words: say “only ate half the sauce” and the numbers redo themselves.
Do I need an account?
No. Riveryn is designed as a local-first app with no required account.
Does Riveryn track me for ads?
No. Riveryn does not use ad tracking, advertising SDKs, or health and nutrition data for targeted advertising.
Who is Riveryn for?
Riveryn is for people who eat normal meals, want brighter days after eating, and do not want food tracking to become a second job.
