Abstract
Howbout still has strong brand momentum and a 4.6★ lifetime rating, but recent reviews show a clear opening: users who relied on free color coding, simple shared planning, and private household calendars now feel pushed into premium, forced onboarding, and confusing social defaults.
Background
Howbout: shared calendar is a free shared-calendar and social event-planning app for friends, couples, and families. Its listing claims 10M people using it, 200M+ plans made, and 1B+ social views; the install snapshots provided show 2,091,123 installs on 2026-09-06.
What it does
Shared calendars, availability, event planning, polls, chat, widgets, and sync with Google Calendar, Outlook, and iCloud.
What changed
Recent reviewers say free color customization and categories were reduced or moved behind Howbout+, while existing event colors were reset or stripped.
Why it is soft
The backlash is about trust and workflow disruption, not lack of demand. Users still like the shared-calendar idea; they are angry that their organization system changed under them.
Strengths
This is not a weak incumbent. Positive reviewers still call the core useful for couples, families, friend groups, work schedules, sports, school, and planning trips. Event chat, availability sharing, colors, and habit are real advantages a solo competitor would need to earn from zero.
Proven habit
Several unhappy users say they used Howbout for years, had hundreds of events, or got friends and family to install it. That means the product category has retained behavior, not just curiosity.
Social utility
When it works, users value seeing when others are free, inviting groups, and keeping event chat out of normal messaging threads.
Brand reach
The Play description’s TikTok and social-view claims, plus the install snapshots, show a discoverability engine a solo builder cannot match directly.
Market gap
The gap is a calmer shared calendar: keep core organization free, make privacy understandable, and avoid forcing social growth mechanics before users have seen value.
Color coding moved to premium
The loudest recent cluster is the color/category update: users say custom colors disappeared, existing calendars turned gray or blue, and previously free organization now requires payment.
Forced invites before value
A repeated onboarding complaint is that users must invite friends, use codes, or add people before they can evaluate the calendar, which feels spammy and blocks couples or households.
Privacy and phone-number friction
Reviewers object to mandatory phone numbers, unclear privacy settings, and social notifications that expose plans or updates to the wrong people.
Reliability and support gaps
A smaller but serious cluster mentions crashes, event times changing, events not deleting for others, sync awkwardness, and AI or automated support when users need account help.
Howabout used to be the go to for me and friends to easily create events and invite one another but as each update comes, the app's functionality has gotten worse to try and encourage you to buy premium. The app has stripped all of the colours from previous events to get you to categorise them but you are only limited to 5 free ones that you cannot change the name and removed some of the previously free colours. The lack of customisability is why we've all had to stop using it.
Requiring EVERY person to add 3 friends before they're allowed to even use the app is stupid and ridiculous. You have lost approximately 11 potential customers among my group of friends who were unable to join due to this policy. It's terrible.
Really tried to get people to use this app, through all the image sending issues etc, the thing that killed it was sending notifications to friends for things they weren't invited to. That's surely the biggest no no, telling everyone things they're not invited to. We're lucky it didn't cause a row really. The privacy settings are too confusing if that's what the problem was. Group gave up with it, back to messenger chats
- Make colors and custom categories permanently free. That is the emotional wedge: the competitor should promise unlimited event colors, editable category names, and no future downgrade of existing calendars.
- Let one person use it before inviting anyone. Support email login, optional contacts, private household calendars, and a demo mode so couples and families can test the app without spamming friends.
- Charge only for durable extras. Keep the core calendar, sharing, colors, and basic widgets free; monetize backups, exports, advanced sync, and larger shared groups without touching existing data.
Build complexity
Estimated, not derived: one part-time solo developer, no funding, no team, and no paid acquisition. A full Howbout clone is too big; the v1 should be an Android-first shared calendar for couples, families, and small friend groups, with privacy-first onboarding and free color organization.
| Workstream | Weeks |
|---|---|
| Android calendar UI, event editor, colors, categories | 3 |
| Accounts, households/groups, invites, permissions | 3 |
| Backend sync, notifications, deletion consistency | 3 |
| Basic Google/Outlook/iCal import or sync path | 2 |
| Widgets, export, billing, Play listing, QA | 3 |
| Total | 14 |
Expected revenue
Estimated, not derived: the safer pricing is freemium with the complained-about features left free. Assume $2.99/month for Plus, limited to backups, export, advanced sync, and larger groups; month-12 revenue depends on organic search and switchers, not paid ads.
| Month 12, monthly funnel | Estimate | Assumption |
|---|---|---|
| Installs | 5,000 | Organic only |
| Activated | 2,500 | Created first shared calendar |
| Retained | 1,200 | Still using after 30 days |
| Paid | 600 | Plus for sync/backups/groups |
| Revenue | $1,800/month | At $2.99/month, rounded |
Biggest challenges
The hard part is not drawing a calendar grid; it is earning trust in a category where calendars contain sensitive personal data, while competing against an incumbent with strong brand awareness and social-network habit.
Cold-start network problem
Shared calendars become useful when other people join. Without paid acquisition or TikTok reach, the v1 must win small groups one household at a time.
Calendar integrations
Google, Outlook, and iCloud sync create OAuth, permissions, recurring-event, timezone, and support work that can swamp a part-time developer.
Privacy mistakes are fatal
The review about notifying people who were not invited shows the risk: one confusing default can create social harm and permanent distrust.
AI angle
There is no strong AI moat here. AI could help with internal testing, support drafting, or optional natural-language event creation, but the market gap is trust, privacy, reliable sync, and free color organization — not an unsolved AI capability.
Do not lead with AI
Users are complaining about paywalls, onboarding, privacy, and broken organization. An AI-branded calendar would not directly answer those complaints.
Useful but secondary
A later feature could parse screenshots or messages into events, but it should not change the 14-week v1 estimate or the $1,800/month revenue estimate.
Conclusion
Build it. But build it narrowly: an Android-first shared calendar for households and small friend groups, not a full social planning network. The wedge is credible because Howbout’s own loyal users are angry about color coding, forced invites, and privacy defaults; the ceiling is limited because sync, trust, and network effects are hard for one part-time developer.
