Real numbers in. Not vibes.

Ren doesn't make calories up. When you say "had the harvest bowl at sweetgreen," it searches the web for the actual menu, cross-checks every ingredient against a verified food database, and shows you which numbers came from where. The dressing's an estimate. The wild rice isn't. You can see the difference.

Connects what other apps only see half of

A food app sees calories. A sleep app sees hours. A calendar sees meetings. None of them connect "five hours of sleep all week + deadline Friday + only coffee since 10am" into one decision. Ren does.

sleep ↓ 5h avg · gym 6pm · deadline fri
heads up — you've slept 5h-ish all week and there's a deadline friday
eat real food before noon. carbs by 4 if you're still hitting the gym at 6
good call. doing eggs + rice now
nice. log when you're done, i'll check in at 3:30

Your data, in a workspace you own

Connect Notion and every meal lands in your workspace as a row you can edit, filter, or chart. Walk away anytime — the data stays with you. No vendor silo, no export ticket, no lock-in.

(5)

Ask "am I on track" anytime

A real coaching read of your week — not a dashboard. Ren runs the aggregates against your logs and tells you straight where the goal stands. The numbers do the math. The coach does the talking.

sun 9:42pm
am i on track this week?
honest read — calories landed (avg 2,180), protein hit (141g/day). the soft spot is sleep, you're 40 min short of last week.
you got 3 of 4 sessions in. push lights-out earlier sun + mon and you'll hit the cut without losing the lift.
what about the dinner thursday?
factored. you bought the buffer with the wed deficit. order what you actually want.

why we built it

I connected my hectic schedule and finally stayed consistent with the gym for a month — enough to build the habit again. It remembers my protein shake, my next AI journal to read, and reminds me to stick with the goal.
