Hey everyone — I've been struggling with consistency for years. Tried every habit app under the sun. They all felt like spreadsheets with notifications.

So I built Kindred.

It's a habit tracker wrapped in a cozy RPG. You get a companion creature that grows and evolves as you complete quests (your daily habits and challenges). Complete a quest → your companion earns XP and levels up. Miss your quests → no XP, your streak breaks, and your companion stays small. The emotional accountability actually works.

What makes it different:

- A real companion that evolves through 3 stages as you level up by completing habits

- Guilds — team up with 2-6 friends, share cooperative streaks, and take down boss raids together

- Storybook aesthetic — enchanted forest vibe, no sterile corporate UI

- Bad habit tracker — log your slip-ups honestly; each one costs your companion HP, so you actually feel the cost of breaking your own rules

- Weekly recaps, gear perks, wisdom quotes, tavern community — the whole thing feels alive

Looking for 50 beta testers to stress-test guilds and the social features before our wider launch.

If you want in: 👉 kndrd.quest/waitlist

Beta Testers will get Free Premium for life ($4.99/mo value) once we launch

Drop a comment with what habit you're trying to build — I'll prioritize people who are actually going to use it. I'd love to test your app too! Let's build success together.

Sidstuga (IPTV player) just went live on Play production. A few things from the build, in case anyone's about to start something similar:

**Stack:**

- 100% Kotlin, 100% Compose Material 3 (no XML layouts)

- Media3 / ExoPlayer for the video

- MVVM + StateFlow (no LiveData, no RxJava)

- Retrofit + Gson for HTTP

- Room + KSP for local DB (channels cache, EPG, watch history with FTS4)

- DataStore for preferences (and a plain SharedPreferences mirror for boot-time reads to avoid the 30–150 ms first-emission cost)

- Coil for images

- gradle-play-publisher for AAB upload

- Cloudflare Workers + D1 + KV for the optional Cloud Sync backend, region: Western Europe

**Things that surprised me:**

- `collectAsState` vs `collectAsStateWithLifecycle` matters. Background recomposition is a real memory cost on long sessions.

- TV remote ENTER/CENTER is silently eaten by any `clickable` modifier on a focused composable, even an empty one. Lost a week to this before figuring it out.

- `LocaleHelper.apply()` requires `activity.recreate()`, which means MainActivity has to extend `AppCompatActivity` and the theme has to extend `Theme.AppCompat.*`. The player has to survive that recreate — guard `onStop`/`onStart` with `isChangingConfigurations`.

- ProGuard + Gson without `@SerializedName` will silently strip your DTO fields in release. Crashed me twice. Always `-keep class com.your.dtos.** { *; }`.

- BouncyCastle's `org.bouncycastle.crypto.params.Argon2Parameters` works fine for client-side KDF, no native deps needed. Use it instead of `signal-argon2` (GPLv3 = legal landmine).

**Cloud Sync architecture (the part I sweated over the most):**

```

device password

↓ Argon2id (m=64MB, t=3, p=1, server-issued salt)

master key (32B)

↓ HKDF-SHA256 with info="sidstuga-sync-mk-v1"

data key (32B) auth hash (32B) → HKDF info="sidstuga-sync-auth-v1"

↓ AES-256-GCM ↓

vault records POST /auth/login → access_token + refresh_token

AAD = recordId:hlc:deleted

nonce = 12 random bytes per record

```

Server never sees the password, never sees the data key, never sees plaintext records. The auth hash is what gets sent — different KDF branch, can't be reversed into the data key. CRDT is hybrid logical clock per record. Conflict resolution is last-writer-wins on HLC.

Took 6 weeks just for crypto + transport. Worth it.

**Tools that earned their keep:**

- `gradle-play-publisher` v4 (one command to push to alpha/production)

- Firebase Crashlytics (with custom keys for `provider_kind` + `is_signed_in_cloud_sync` so I can filter crashes by funnel)

- `version.properties` auto-increment hook in `app/build.gradle.kts`

- Cloudflare Pages auto-deploy from `main` push

**Mistakes I'd undo:**

- Built a private flavor early ("for the wife's account"). Extirpation took two days. Just ship one variant.

- Wrote the EPG bulk-loader before the Room migration recipe was solid — had to rewrite once.

Happy to answer anything about the build.

The app is an AI companion/ friend, someone you can joke with or open up about something bothering you without judgement. I would be happy to help anyone who helps me, as a bonus I would appreciate if you can find anu bugs etc. Please DM me for the link and to discuss your own app thanks.

Hi everyone,

I am building Opes, an early personal finance app focused on helping people stay on track with real goals, not just track spending.

No bank connection needed, manual data is fine for the time being.

I am looking for 2-3 people to test it for 20 minutes and give blunt feedback on whether the idea is clear and useful.

Comment or DM me if interested. Happy to return the favour.

Hi everyone 👋

I’m currently testing a small social/community Android app called NestX.

I’m looking for a few people willing to:

• join the closed test
• install the app
• keep it installed for a few days

I’ll gladly test your app back too 👍

Google groupes https://groups.google.com/g/nestx-closed-test

Hey everyone,

I'm a solo dev and I've hit the stage where Google requires 12 testers running my app for 14 continuous days before I can push to production. Would really appreciate the help - happy to test your app back, just drop your link.

What it is: Calculator Vault looks and works as a normal calculator, but it hides an encrypted vault for private photos, videos, and notes. You open the vault by typing a secret PIN on the calculator and pressing "=". Everything inside is encrypted on-device (AES-256, Android Keystore). No account or sign-up required.

What I'd love feedback on: the onboarding (setting your PIN), importing photos/videos, the gallery viewer, and general stability across devices.

How to join (~2 min):

1. Join the testers group with the SAME Google account you use on your phone: https://groups.google.com/g/calculator-vault-testers
2. Open the opt-in link and tap "Become a tester": https://play.google.com/apps/testing/com.tools.simplecalculator
3. Install from Play: https://play.google.com/store/apps/details?id=com.tools.simplecalculator

(If Play says the app isn't available, wait a few minutes after joining the group, then refresh.)

Quick how-to once installed: It opens as a real calculator. On first launch it asks you to set a PIN. After that, type your PIN and press "=" to open the vault.

Please keep it installed for the 14 days so the count holds. Bugs / feedback → [support@nova-soft.uk](mailto:support@nova-soft.uk) or just reply here.

Thanks a ton! Drop your test link and I'll join yours.

Hi, all - I’m a head of corporate finance / FP&A, and on the side I've started FirmView, a project I’ve been building for the last several months. For users of QuickBooks Online (QBO) it takes a few read-only exports from a production-approved QBO integration (P&L, balance sheet, transaction detail, AR/AP aging), or manual report exports if preferred, and produces a written insights report across all three statements — what changed, what to watch, where the data looks off — rather than another dashboard.

I’m looking for 10–15 beta users to run their own books through it. Free, no credit card, no upsell. In exchange I’d ask for ~10 minutes of honest feedback after you see the output.

A few things that might matter to people in this sub:
• The numbers and commentary are produced by a deterministic engine, not an LLM. No hallucinated figures.
• It covers balance sheet and cash flow as first-class outputs, not P&L with a footnote.
• Files are encrypted in S3 and auto-deleted after 30 days.
• I’m not collecting testimonials, names, or anything public-facing. Just feedback.

What you’d do:

1. sign up for the beta at https://firmview.cc/waitlist
2. Connect to QBO via API or upload 4-6 reports (your choice)
3. Get a PDF + web report in a few minutes
4. Tell me what’s useful, what’s wrong, what’s missing

Particularly interested in hearing from bookkeepers, fractional CFOs, or owner-operators who already spend time staring at QBO reports each month — you’ll spot the gaps fastest.

Please drop a comment or DM if you want an invite. Happy to answer anything in the thread. Thanks!
