Sound familiar?

Struggling with your cat's health management?

Each photo records a health score, making changes visible through numbers.

Guessing by gut feeling

"She's eating, so she's probably fine, right?" "He's sleeping as usual today too..."

But cats hide their illness. Even if they're eating and sleeping, something could be quietly changing inside.

Can't answer the vet's questions

Vet: "When did the appetite start to decrease?" You: "Um... a week ago... or maybe longer..."

That frustration at every checkup: "I thought I was watching closely." Without records, you can't share what you want to.

Can't notice gradual changes

Looking at a photo from 6 months ago: "Wait, did she always look like this?" You can't tell if she's thinner or heavier.

Because you see your cat every day, you miss gradual changes. By the time you notice, the vet says "I wish you had come sooner."

With CatsMe, photos become data.

Each photo records a health score, making changes visible through numbers.

"Probably fine" becomes reassurance through numbers

"Looks healthy" is now backed by a score. No more anxious days.

"Since when?" — no more panic

Auto-recorded with every photo. Tell your vet "It started 2 weeks ago" right away.

"Didn't notice" — the app notices first

Get alerted when the score drops. Prevent "I wish you had come sooner."

User Reviews

Real feedback from cat owners using CatsMe

★★★★★

5-year-old Scottish Fold

I was unsure whether to go to the vet, but since I started recording daily with CatsMe, I can notice small changes. The peace of mind is different.

Mikan's Mom — Tokyo

★★★★★

3-year-old American Shorthair

When I showed my vet the CatsMe records, they said "this is helpful". It's great to visualize changes in cats that are hard to describe in words.

Leo's Dad — Osaka

★★★★★

12-year-old Calico

I was worried about health management for my senior cat, but daily checks have become a habit and I feel secure. I'm happy it's free.

Hana's Owner — Fukuoka

★★★★☆

Love the features. Just needs better usability

The score accuracy is surprisingly spot-on. My cat's score was low one day, and the next day she started sneezing — I was shocked. I gave 4 stars because I wish the photo guide was a bit clearer. Looking forward to future updates!

Game-changer for tracking 3 cats separately

With multiple cats, I honestly couldn't keep track of who ate how much or how many litter box trips they made. CatsMe keeps records separate for each cat, so I can instantly see things like "this one's score is dropping." Before, I'd sometimes not notice until it was already vet-level serious, so catching things early is huge.

★★★★☆

Accuracy reportedly improves with continued use

Been using it for about 2 weeks. Honestly, the first few times I wondered "Is this accurate?" But as records accumulated, the score trends started matching actual health patterns. Giving 4 stars since I can't fully judge yet, but it's impressive how much you get for free.

Love that you just take a photo

I used a different health management app before, but quit after 3 days because there were too many input fields. CatsMe is just photos. That's why I keep going. Even I've kept it up for 2 months, which says a lot. It's also surprisingly fun to see accumulated data in graph form.

★★★★★

Great for people who just adopted a rescue cat

I just adopted a rescue cat with unknown medical history. I was anxious not knowing what's "normal" for this cat, but by taking daily photos with CatsMe, I started to see her baseline. This is an app especially for first-time cat owners.

40s — USA

★★★★☆

Great app, but needs more exposure

After 3 months, I'm very satisfied with the features. I gave 4 stars because none of my cat-owning friends have heard of it yet. If more users join, the data and accuracy will only improve. Also, the occasional check reminder notifications are quietly helpful.
