Hey HN, I’m the founder of TikTask. I launched it about 3 months ago.

TikTask started as a message scheduler, but I kept running into the same reality: people don’t just want “send later”, they want reliable follow-up routines for business and for daily life.

What TikTask is: a message scheduler + on-device automation app for Android. You schedule messages and routines, and the execution happens locally on your phone, not on my servers.

What “on-device automation” means (and why it matters):

On-device (TikTask): your phone executes the scheduled actions at the right time. No cloud worker sending messages, and no need to wire up official APIs for common personal workflows.

Official APIs: great for businesses at scale, but usually require a backend, verification/compliance, templates, and per-message costs, and they don’t fit many “personal phone” workflows.

Cloud automations: powerful, but your automation and often your content lives off-device, which can add cost and privacy considerations.

With on-device automation, the model is simple: private by design (your data stays on your phone) and cheap to operate (no per-message infrastructure), which is especially useful when you’re growing a small business and want to automate follow-ups without building a backend.

Use cases I built for:

Business: lead follow-ups, client reminders, appointment nudges, promo announcements

Daily life: birthdays, family reminders, recurring check-ins, routines you don’t want to forget

The hard part (and the part I’m proud of): reliability. Android background limits and OEM battery managers can silently kill automations. A lot of the work went into a “System Monitor” style checklist that helps users enable the right settings so schedules actually run.

I’d love feedback from HN:

Does this positioning make sense, or does it confuse people (“message scheduler” vs “automation”)?

If you’ve built anything that depends on Android background execution, what reliability traps did you hit?

What would you want to see to trust a scheduler like this for business follow-ups?

If anyone wants to test premium/locked features and give blunt feedback, reply or DM and I’ll share a promo code.
