The calorie app for people too lazy to count calories

Log what goes over
not what you eat

Set your calorie budget once from your TDEE, then live your life. Days you stay under — nothing to log at all. Days you go over, open the app and confess. Takes under 30 seconds.

Who OopsLog is for

Not built for marathoners who weigh every grain of rice — built for people who want to stay in shape without changing their life

🔥
Trying to lose weight

Want to slim down without logging every meal? Rein in just the days you slip — that's enough.

💪
Lifters watching their physique

Keep the long-term plan on track. Cheat day? Log the karma and know exactly how much to pay back.

🧋
Sweet tooths trying to quit

Bubble tea, soda, desserts — the main boss fights. OopsLog spotlights exactly those culprits.

😮‍💨
Burned out on calorie apps

Downloaded one, deleted it within 3 days because logging was exhausting — this time, no oops means nothing to log.

Why people quit calorie counting
within 2 weeks

Because typical apps make you log every grain of rice, even though you already know what a normal meal looks like — what actually wrecks the plan is the part that goes "over"

How OopsLog thinks

Three steps — and only one ever repeats (only on days you slip)

01
Set your budget once

Enter your weight, height, age and activity level. The app computes TDEE + BMI and turns it into one daily calorie budget. Done — never touch it again.

02
Live your normal life

Stay within plan = do absolutely nothing. Your streak keeps running on its own and the app stays silent — like continuous integration for your body: no breakage, nothing to report.

03
Log only when you blow it

Type a few words or snap a photo — Kalgooro AI converts it into calories instantly, files it in your karma notebook, and shows how to pay it back. Done in 30 seconds, no overnight guilt.

spot your own patterns

It's not logging for logging's sake — OopsLog shows how many days you went over this week, what trips you up most, and how far your streak can go.

Everything OopsLog does for you

The full toolkit for lazy-mode body control — already thought through, you just live.

🧮
TDEE + BMI calculator

Enter weight, height, age and activity level, get one daily calorie budget. Set once, done.

🤖
Oops AI does the math

Type a few words or photograph the damage — AI turns it into calories instantly. No guessing, no googling.

📓
Karma notebook

Keeps only the days you went over, with a payback plan every time — logged to repay, not to feel guilty.

🔥
Clean-day streak

Counts consecutive days on plan. Motivation without pressure — on normal days the app stays silent.

🍩
Watches the sweet stuff

Bubble tea, soda, desserts — the boss level most of us lose to. OopsLog keeps its eyes right there.

♻️
Karma resets weekly

A bad week doesn't ruin the month. Karma expires every week — you always get a fresh start.

The karma notebook

You don't log to feel guilty — you log to know exactly how much to pay back. Karma (calories) always comes to collect, but it can always be repaid, too.

Photo or text — Oops AI does the calorie math for you

Don't know where to start?
Start with a single rule

The fewer the rules, the clearer what counts as an "oops" — level up after a 21-day streak.

LEVEL 1
Start with IF 16:8

Eat anything within an 8-hour window. One rule — don't think about anything else yet.

Counts as an oops when
You eat outside the 8-hour window
LEVEL 2
Cut sweets, cut sugar

Same IF, one new rule — sugary drinks are the boss level most people lose to.

Counts as an oops when
You eat outside the 8-hour window
Bubble tea, soda, desserts
LEVEL 3
+ Move once a week

Everything from before, plus at least one workout a week — literally just one.

Counts as an oops when
You break any Level 2 rule
You didn't move at all that week

From people who quit
logging every meal

Frequently asked questions

Before you download — in case you were wondering the same things.

Is OopsLog free?+
All core features are free — TDEE budget setup, the karma notebook, streaks, and Oops AI calorie estimates, at no cost.
How accurate is Oops AI?+
They're estimates to show roughly how far over you went — not lab values. But accurate enough to know what to pay back, which is all OopsLog needs.
Do I have to log every meal like other apps?+
Not at all — that's the whole point of OopsLog. Days on plan need nothing. You only log the days you break the budget or the rules.
Is my data safe?+
Your eating and weight data stays private. We never sell it to anyone, and you can delete everything at any time.
Does OopsLog give medical advice?+
OopsLog isn't a doctor — just a tool that makes calorie control easier. For health conditions or specialized nutrition, please consult a physician or dietitian.
How is the daily calorie budget calculated?+
From TDEE and BMI, based on the weight, height, age and activity level you enter, converted into a single daily budget. Adjust it later if your weight changes.
