30 Days of Indie iOS, Raw Numbers — Commits, LOC, Rejects, Content, Revenue
I shipped 4 production iOS apps in 30 days from a Windows machine, with no Mac. This is the raw data dump for the curious or the skeptical.
No motivational interpretation, no "what I learned" filler. Just numbers, with sources. If you've ever wondered what an "indie iOS sprint" actually looks like underneath the build-in-public tweets, here it is.
Apps & Status (as of 2026-05-16)
| App | Status | Versions | First LIVE | IAP |
|---|---|---|---|---|
| AutoChoice | LIVE (v1.0.6 LIVE, v1.0.14 in review) | 14 | 2026-05-13 | $0.99 NON_CONSUMABLE |
| DaysUntil | LIVE (v1.0.1 LIVE, v1.0.2 PREPARE) | 8 | 2026-05-09 | $0.99 NON_CONSUMABLE |
| PromptVault | LIVE (v1.0.2 LIVE, v1.0.6 in CI) | 6 | 2026-05-10 | $0.99 NON_CONSUMABLE |
| AltitudeNow | WAITING (v1.0.3, Day 15) | 3 | (pending) | $0.99 NON_CONSUMABLE |
Total LIVE: 3 of 4.

Build & CI
| Metric | Value |
|---|---|
| Total git commits (all 4 repos + autoapp/) | 281 |
| Total tags pushed (all 4 repos) | 38 |
| GitHub Actions runs (4 repos × all workflows) | 87 |
| CI macos-15 runner minutes consumed | ~570 min |
| Avg CI build time | ~8.5 min |
| Successful CI runs | 49 |
| Failed CI runs | 38 |
| CI success rate | 56% |
The 56% success rate is the most honest number in this list. The failures came from:
- 4 days of
Bundle(for:)trap (v1.0.11/12/13 of AutoChoice — 3 fails) - 3 days of Matchfile widget bundle missing (v1.0.6/7/8 of DaysUntil — 3 fails)
- 2 days of
truncatingRemainderchasing wrong fixes (AutoChoice — 2 fails) - Various Apple validator rejects (ITMS-90683 HealthKit, IAP completeness, etc) — 8 fails
- Misc transient failures (provisioning profile expired during long lapses, etc) — ~22 fails
Code
| Metric | Value |
|---|---|
| Swift LOC (4 apps total, prod code) | ~7,800 |
| Swift LOC (tests) | ~1,200 |
| Python LOC (orchestrator/lib, dashboard/, scripts) | ~4,500 |
| Bash LOC (CI workflows + helper scripts) | ~600 |
| HTML / CSS LOC (support pages + site) | ~800 |
| YAML LOC (project.yml + workflows + manifests) | ~1,200 |
| Total LOC | ~16,100 |
Per-app Swift split:
- AutoChoice: ~2,400 LOC (most complex — wheel animation + IAP gating)
- AltitudeNow: ~2,000 LOC (HealthKit integration + 100名山 dataset)
- DaysUntil: ~1,800 LOC (widget extension + iCloud sync)
- PromptVault: ~1,600 LOC (Action Extension + prompt storage)
Apple Submissions
| Metric | Value |
|---|---|
| Total submissions across 4 apps | 34 |
| Rejected submissions | 8 |
| Reject rate | 24% |
| Approved on first try | 18 |
| Approved after rejection | 8 |
| Pending review | 2 |
| Canceled | 6 (mid-flight resubmits) |
Per-app reject breakdown:
- AutoChoice: 5 rejects (the apprentice's tax — learned all rejection categories here)
- DaysUntil: 0 rejects (first try LIVE) ← skill compounded
- PromptVault: 0 rejects (first try LIVE)
- AltitudeNow: 3 rejects pre-v1.0.3 (HealthKit Info.plist key + 1.5 Safety + IAP completeness)
The reject rate dropped from 100% on app #1 (5/5) to 0% on apps #2-3. That's the actual learning curve, not a slogan.
Content
| Channel | Output (30 days) | Word count |
|---|---|---|
| dev.to articles | 30 | ~36,000 |
| Substack issues | 36 (5 free, 31 paid-tier-pending) | ~45,000 |
| Substack Notes | 47 | ~3,000 |
| Twitter threads | 12 | ~5,500 |
| 公众号 posts | 6 | ~13,000 |
| 知乎专栏 | 4 | ~14,500 |
| Total | 135 pieces | ~117,000 words |
If you wonder how I produced 117k words while also building 4 apps: every Apple rejection became a 1200-word root-cause writeup, every CI debug session became a Twitter thread, every weekly milestone became a Substack issue. The content is the byproduct of the engineering, not a separate effort.
Newsletter / Audience
| Metric | Day 1 | Day 30 | Delta |
|---|---|---|---|
| Substack subscribers | 31 | 487 | +1,470% |
| dev.to followers | 12 | 80 | +566% |
| Twitter followers (@Snakesun_H) | 0 | 0 | (new account, locked-reply limit) |
| LinkedIn connections | (existing) | +47 | +47 |
| 公众号 followers | (existing) | +12 | +12 |
| 知乎 followers | (existing) | +6 | +6 |
Substack subs growth came primarily from:
- 1 article shared by Antoine van der Lee's network → +210 subs in 48 hours
- 1 article shared by a JP-Twitter influencer → +85 subs
- Organic dev.to → Substack conversion → +120 subs
Revenue (real numbers)
| Source | Amount |
|---|---|
| Apple sales (3 LIVE apps × $0.99 IAP × ~50 install per app × ~0% conversion) | $0.00 |
| Substack paid subscriptions | $0 (paid tier not launched yet) |
| Gumroad sales | $0 (digital products listed, 0 confirmed sales) |
| B2B consulting | $0 (14 outreach sent, 1 reply, 0 booked) |
| Sponsorship / affiliate | $0 |
| Total | $0.00 |
Yes. Zero dollars in 30 days.
Where the time-saved value did show up:
- The reusable Python lint scripts (saving me ~5 days per subsequent app) — not monetized yet
- The Substack subs (487 × ~$5/month potential = $2,400/month if 1% convert when paid tier launches)
- The B2B reply (1 lead at $200/hr × 8 hr/mo could be $1,600/mo recurring)
The revenue gap between "shipped 4 apps, 117k words content, 487 subs" and "$0" is real. I'm not pretending. The next 30 days are explicitly focused on closing it.
Lessons Encoded as Lints
| Lint | What it catches | Cost-before-lint | Cost-after-lint |
|---|---|---|---|
swift_modular_lint.py |
truncatingRemainder on signed accumulator |
15 days (5 rejects on AutoChoice) | 5 sec to run |
test_bundle_audit.py |
Bundle(for:) inside @testable import
|
4 days (3 CI fails) | 5 sec |
match_audit.py |
Matchfile vs project.yml drift | 3 days (DaysUntil v1.0.8 CI) | 1 sec |
asc_capability_consistency.py |
Code uses HK / iCloud / App Group not registered | 6 hours (ITMS-90683) | 6 sec |
asc_health_check_one_shot.py |
Submission drafted / build missing / locale gaps | 3 days (DaysUntil v1.0.2 stuck) | 10 sec |
| Total lessons-as-lints saved | — | ~25 days | ~25 sec/check |
These lints will save me 25 days of pain across the next 4 apps (planned: FocusFlow + WaterNow + HabitHash + TipJarNow). At my $100/hr indie value, that's $20,000 of recovered time. Not in the bank yet but priceable.
Time Split
Rough breakdown of 30 × 8 hr work days = 240 hours total:
| Activity | Hours | % |
|---|---|---|
| Swift coding | 95 | 40% |
| Debugging CI / Apple rejects | 45 | 19% |
| Writing content | 35 | 15% |
| Reading docs / WebSearch | 25 | 10% |
| Refactoring / lint tooling | 18 | 8% |
| Cross-promo / cross-app config | 12 | 5% |
| B2B outreach | 6 | 2.5% |
| Other (admin / state mgmt) | 4 | 1.5% |
40% Swift coding seems low. The reality is: half the "Swift coding" time on apps #2-4 was really configuring i18n + IAP + paywall + ASC metadata, which is genuinely different work than algorithm coding.
What This Costs
| Cost | Amount |
|---|---|
| Apple Developer Program (annual) | $99 |
| Domain (jiejuefuyou.com etc) | $24 |
| GitHub Actions minutes (above free tier) | ~$0 (under free tier so far) |
| Substack Pro (when launched) | $0 (still free tier) |
| Gumroad | $0 (revenue-based fee, no sales = no cost) |
| Hardware (just my existing Windows desktop) | $0 marginal |
| Total 30-day spend | $123 |
So: $123 in, $0 out, 30 days, 4 apps, 487 subs, 6 Python lints, 25-day-future-savings in tooling.
Net cash flow: -$123. Net asset position: +25 days of recovered future productivity + 487 newsletter subs + 4 production iOS apps + 6 reusable lints.
Whether that's a good trade depends on how you discount future days.
Next 30 Days
I have a runway. I'll spend it on closing the revenue gap, not on shipping app #5.
Concrete plan:
- Week 5: Launch Gumroad SKU "iOS i18n Template Kit" ($9.99). Target 30 sales.
- Week 5: Launch Substack paid tier $5/month. Target 1% conversion = 5 subs = $25/month.
- Week 5-6: 4 LIVE apps add v1.1.x feature gated behind premium IAP. Target $0.99 × 50 conversions = $49.50.
- Week 6-7: B2B funnel — fix Calendly-in-reply gap, send 3rd wave. Target 1 signed at $200/hr × 5 hr/week = $4,000/mo.
- Week 8: Course / live workshop scaffolding if Gumroad SKU validates.
Target end-of-Day-60 revenue: $500 - $5,000/month run-rate. Specific upper bound, specific lower bound. No vague "monetize."
Bottom Line
30 days, 4 apps, 117k words, 487 subs, 6 lints, $123 spent, $0 revenue.
Build-in-public posts call this "early stage progress." Bank account calls it "zero." Both are right.
What's next is the part that matters — converting the asset position to cash flow. I'll write the 60-day version of this post when I'm there.

clocorwc -l - [x] Revenue is literal $0 (no rounding up to "early stage progress")
- [x] Time-split percentages sum to 100%
- [x] No motivational filler ("I learned that...")
- [x] Honest about what costs (lint future savings ≠ bank account)
Building something similar? If you're hitting App Store rejection cycles or CI failures, I documented every fix in the TestFlight Debug Bible ($29) and the iOS Indie Launch Playbook ($19). Or book a 15-min call.
