I built a chore app for Muslim families — looking for 5 parents to test one 10-minute flow

Assalamu alaikum — I’m the founder of ChoresFlow. I built it because most family chore apps handle points and rewards, but don’t connect everyday responsibility with the rhythms and values of a Muslim home.

This isn’t another prayer-times app. The core is a family chore board with kid PIN access, points and rewards, plus prayer times visible beside the routines you schedule.

I’m not looking for compliments or a big launch. I’m looking for five parents who can spend about 10 minutes testing one specific flow:

  1. Create a family account

  2. Add one child

  3. Assign two chores

  4. Tell me the first moment that felt confusing, unnecessary, or untrustworthy

There’s a 14-day free trial; no card is needed to test the setup flow.

Test it here: https://www.choresflow.com/signup?utm_source=reddit&utm_medium=community&utm_campaign=proof_sprint&utm_content=muslimdevelopers_beta

I’ll share what I learn and what I change. Honest criticism is much more useful than encouragement at this stage. Jazakum Allahu khayran.

7 non-obvious gotchas building a production WhatsApp + AI workflow in n8n

Spent the last few months running a WhatsApp AI auto-reply on self-hosted n8n + WAHA + OpenAI for a small business. Sharing the non-obvious stuff that ate the most time.

  1. WhatsApp's LID addressing silently breaks replies.

Inbound messages now arrive with from: "<lid>@lid" where the LID is not the customer's phone number. Reply to it and the message goes into the void. The real phone sits in payload._data.key.remoteJidAlt. Parse node has to check for the u/lid suffix and fall back to remoteJidAlt before stripping. Cost me a weekend of "why is the bot ignoring half the customers."

  1. WAHA redelivers webhooks on flaky networks.

I started getting duplicate replies. Fixed with a small processed_msgs table and INSERT ... ON CONFLICT DO NOTHING against the message ID. Auto-cleanup after 1 hour.

  1. Don't let the LLM invent prices.

The model will confidently quote "$249" for something you charge $129 for. I keep a knowledge table (question/answer) with pg_trgm fuzzy match on the customer's message, and inject matched rows into the system prompt as "USE THESE EXACTLY." The prompt also computes with-tax totals so it can say "$129 plus tax, about $139 out the door."

  1. Business-hours math is harder than it sounds.

"Can I come at 6:55?" when you close at 7 means "yes but it won't be ready today." I encoded close-time + service-duration logic into the system prompt rather than hardcoding replies — keeps the language natural.

  1. Conversation memory has to be cheap.

Pulling the last 10 messages into a single Postgres json_agg query keeps round-trip under 30ms. Don't loop n8n nodes for this — one query, hand the result to the prompt builder.

  1. Have a fallback reply.

When OpenAI returns 429 or 500, send a configurable fallback message instead of going silent, and flag the owner notification so a human follows up. continueOnFail: true on the LLM node is doing a lot of work.

  1. HMAC-verify your webhook.

WAHA signs every outbound webhook with HMAC-SHA512 if you set WHATSAPP_HOOK_HMAC_KEY. 10 minutes to add a Code node with constant-time comparison and throw on mismatch. Cheap insurance.

Total cost: ~$0.30 per 1,000 messages on gpt-4o-mini. Everything else free if self-hosted.

Happy to answer questions in the comments — half of n8n is figuring out which abstractions are worth building.
