EatAWhale's answer:

Web app: TypeScript and React 19 on Next.js 16 (App Router), deployed on Vercel. Prisma is the ORM against a serverless Postgres database on Neon. Auth is NextAuth v5 with Google and Apple sign-in. The web app is an installable PWA with a Serwist service worker and Dexie (IndexedDB) for offline access, so check-ins work with no connection and sync when it returns. Tailwind CSS and Framer Motion handle the interface and animation.

Mobile: React Native via Expo for the native iOS and Android apps, sharing the same backend API.

Payments: Stripe Checkout on the web, native in-app purchase on iOS and Android, with a shared entitlement layer so a purchase on any platform unlocks all of them.

EatAWhale's answer:

EatAWhale is a consumer product sold directly to individuals, so it has no enterprise or business customers to name. Its users are individual hobbyists, learners and musicians. The app launched in 2026 and is independently built and funded, with no outside investment.

EatAWhale's answer:

Two things, and neither exists elsewhere in the category.

It prices your hobbies. Attach a subscription, a class, or a one-off purchase to an interest, and EatAWhale works out what each session actually costs. Spend $2,000 on a piano, play it twelve times, and it tells you that is $167 a session. The number updates every time you check in.

It treats cadence as a first-class idea. Most trackers assume daily, so anything less breaks a streak. EatAWhale asks how often you actually want to do a thing, from daily to monthly, and a two-week gap on a two-week rhythm counts as on track. Streaks exist and they follow the schedule you chose. You also set how firmly the app pushes, anywhere from Chill to Ludicrous.

EatAWhale's answer:

Look at the pricing and platform columns together, because that is where the gap is.

The one-time-purchase habit trackers are locked to a single ecosystem. Streaks is Apple only. HabitNow and Loop are Android only. The ones that run everywhere, Habitify, Habitica and TickTick, all charge a subscription.

One-time purchase AND web AND iPhone AND Android is an empty cell, and EatAWhale is in it. $21 once, no recurring anything, syncing across all three. Three platforms cost more to build and maintain than one, which is exactly why the single-platform apps can be cheaper.

EatAWhale's answer:

People with a few real pursuits and a pile of resources attached to each one.

The typical user is not tracking eight unrelated daily behaviors. They are tracking the teachers, courses, apps, books, tools and subscriptions they have collected around two or three things they genuinely care about, and their problem is that most of it has gone quiet while they use the same two items over and over.

That shows up in how they set cadence. Across the user base only about a quarter of interests are daily, and a fifth are fortnightly or monthly. Nobody builds a habit on a 30-day cadence. A 30-day cadence exists so a thing does not disappear from your life entirely. That is rotation, not discipline.

So: hobbyists, self-directed learners, musicians, readers and makers who want coverage across their interests rather than optimization of one.

EatAWhale's answer:

It started with a number the founder did not want to see.

Across 22 piano-related things he had bought, four teachers, five courses, seven software tools, sheet music, a magazine, sat roughly $9,500 of spend. He was actively using three of them. Everything else had quietly gone dormant, not because he had stopped caring about piano but because nothing was keeping the rest in rotation.

No habit tracker solved it. They are built for daily behaviors and they punish you for gaps, which is the wrong model for a shelf of resources you want to come back to every week or every month. Missing a day on something you check in on monthly is not a failure, but every app treated it like one.

So EatAWhale was built around the opposite assumption: you declare how often you actually want to touch each thing, and the app tells you what is thriving, what is fading, and what each one has cost you per session. It leaves the judgment to you.

The name is the old question about how you approach something too big to finish. One bite at a time. Every check-in is a bite, and they all count the same, five minutes or five hours.
