FAQ

1. Is Hamilton any good?

[APP] I think so - I use it daily.

[DOG] He is the absolute BEST BOY EVER

2. How much does Hamilton cost?

[APP] £3.59 (or local equivalent). I priced it to be approximately the same as a latte, which is my standard unit of measurement for impulse purchases.

[DOG] DO NOT REMIND ME. He was a lockdown puppy and I bought him at the top of the market (He's still worth every penny though)

3. Is Hamilton vibe-coded?

[APP] 100% yes, but human-designed to fit my needs.

[DOG] He wants to create an app called Rate my Vet, with ratings dependent on how they take his temperature.

4. Is that unsafe? Will Hamilton delete data on my phone?

[APP] Everything is a read-only view on Health Connect, and the app has no internet permission. It can't delete your Health Connect data and it can't transmit data.

[DOG] No, but my cat jumped on my keyboard when I was in the middle of typing an insightful LinkedIn post and made me send RUBBISH to my THOUSANDS (20) of followers

5. Is Hamilton active in the background?

[APP] It fetches your data hourly from Health Connect if granted background access, and it works with Android battery saving rules.

[DOG] He's active in the background of my Zoom calls, mostly licking his genitals

6. Is Hamilton tested?

[APP] I've been using it daily and testing and refining it for months. I realise just typing this sentence means someone will find a critical bug the first time they run it and I will look like a FOOL.

[DOG] Only for tapeworm and parvo virus.

7. Do you eat your own dog food?

[APP] I use it every day to show my steps, body comp, workout sessions etc

[DOG] He does, but he would far rather eat whatever it is I have on my plate.

8. Does Hamilton show all your data?

[APP] 30+ metrics, everything except blood sugar and reproductive health

[DOG] The only data he gets is from sniffing lamp posts

9. What units does Hamilton use?

[APP] Metric, Imperial, and you can also configure per metric group to match the strange mix we have in the UK. No furlongs though.

[DOG] Approximately 6 urinations per 20m walked

10. Does Hamilton have any recurring costs?

[APP] I hate apps with subscriptions, and no internet permission means no backend costs so the app is paid once

[DOG] Vets are crooks, is all I will say on this.

11. Has Hamilton won any prizes?

[APP] Not yet

[DOG] Second in the Waggiest Tail Category at the Weald of Kent Ploughing Match. He was ROBBED.

12. Are the metrics on the Play Store yours?

[APP] Absolutely not. I have 5% body fat, do 20,000 steps a day and have a resting heart rate of 12.

[DOG] Yes

13. Where can I see Hamilton?

[APP] https://play.google.com/store/apps/details?id=com.gads.hamil...

[DOG] https://hamiltonapp.github.io/HamiltonApp/dog.html

Excellent. Best of luck!

Not rude at all. Fair on both counts.

I could use a photo of Hamilton, but depending on grooming stage he veers between looking like a freshly clipped sheep or a scruffy mess. I'd have to grab him at exactly the right time. Plus I don't think I could get him to wear the headband.

If the free ones do what you need, then they would be great choices. I guess my target market is people who don't even know F-Droid exists, or would rather stick to the Play Store.

Plus none of those apps are dog-related.

I wanted a dog my whole adult life, and my wife and daughter finally relented when I turned 50, on the condition that they chose the name and the breed. So I got a dog called Hamilton, and a lifetime of people asking if he's named after the musical. Or Lewis Hamilton.

The only dog whistle he responds to are crisp packets rustling.

hamilton_appon The Google Play app review process now regularly takes longer than a week

Finding 12 testers was a struggle for my app [1]. Had to use a mix of LinkedIn begging, work colleagues, friends, and people from random Whatsapp groups I was in.

Once you get over that hurdle for your first release, at least you don't have to do it for every update.

The Play Console is a bit fiddly and I'm always getting random warnings that I need to comply with some new rule by an arbitrary date or my app will get delisted.

hamilton_appon Ask HN: What are you working on? (August 2026)

A vibe-coded front-end to Google Health Connect that displays all health metrics that Health Connect holds in one gui.

It's an attempt to get round the fact that various health apps and vendors pick and choose what they share or show from other sources.
