My role
I reframed the project from a list of features into one research-driven system, connecting feeding, weighing and calorie tracking in a single feedback loop.
- Research synthesis & strategy
- Framework & interaction design
- Low- to high-fidelity prototyping
THE PROBLEM
59% of dogs are overweight. Most owners never notice.
01
The problem
Pet obesity is common, under-noticed and hard to fix.
Perception gap
Owners rarely notice.
The gap between actual weight and owner awareness means many cases go unrecognized.
17%
of owners think their dog is overweight
Unsuccessful attempts
Trying isn’t enough.
Even when owners act, results are inconsistent or short-lived.
Health consequences
It costs years.
Excess weight shortens lifespan and raises the risk of chronic illness.
Lifespan −2 years
More diseases
More aggressionGrowing market
The demand is real.
Pet obesity management and pet tech are both expanding fast.
Problem statementPet weight management lacks an integrated, sustainable system for consistent, long-term health tracking.
02
Research
Weight control depends on manual effort and routine.
We interviewed 11 dog owners — of overweight, previously overweight and healthy-weight dogs — about feeding habits, portion control and health tracking.
20insights on balanced feeding habits

02 What owners told us
Weight control depends on manual effort and routine.
Finding 01 / 04Finding 02 / 04Finding 03 / 04Finding 04 / 04
Portions are estimated, not measured.
Weight tracking is inconsistent and rarely sustained.
Owners feel unsure about their food choices.
Health data is fragmented and hard to read over time.
03
Opportunity
Put the scale inside the routine.
Embedding weighing into feeding removes the separate tracking step, so data is collected every meal without extra effort.
Fitfido
Competitors only solve part of it.

Key features
Every meal becomes a health check.

01 · Smart Scale02 · AI Diet Impact03 · Weight Goal04 · Food Scan
A built-in scale weighs your dog at every meal. No separate weigh-ins, no guesswork.
Portions adjust to weight trends. To keep Mercy on track, the app trims tonight’s dinner from 150 g to 135 g.
Every meal becomes a data point. Weight, calories and goals turn into clear progress in the app.
Scan a treat or a bag of food and Fitfido counts the calories, so portions stay accurate.
05
Companion app · Two prototypes
The app went through two rounds. Try both.
Everything that looks tappable works, and both scroll like the real app. Notes follow along, and in the second one each change appears when you reach it.
