こんにちは、tsuzuki817(@tsuzuki817)です。 収益をぜんぶ公開して次の一手を決める連載「限界個人開発者の月収1000万円計画」、2026年7月号です。

Hi, I'm tsuzuki817 (@tsuzuki817). This is the July 2026 issue of The Struggling Indie Dev's Road to ¥10M a Month, the series where I publish all of my revenue and decide what to do next.

今月のアプリ別ハイライトThis month's highlights by app

うんちくんUNCHIKUN ¥230,630$1,439

iOSの新規ダウンロードは32,579件で前月と横ばい。App Storeの課金75,211円に、iOS広告128,666円、Android広告20,385円、Playの6,368円が乗る。月収の62%を1本で稼いだ計算になる。New iOS downloads were 32,579, flat from last month. On top of $469 in App Store purchases came $803 from iOS ads, $127 from Android ads and $40 from Play. That works out to 62% of the month's revenue from one app.

旅行思い出マップTravelMemoryMap ¥80,989$505

課金70,425円に広告7,878円とPlay2,686円。新規ダウンロードは3,139件で前月から少し減った。夏の旅行シーズンの割に静かだった。$439 in purchases plus $49 in ads and $17 from Play. New downloads were 3,139, down a little from last month. Quiet, for the summer travel season.

7月に出した新作5本The 5 new apps I released in July ¥0$0

DiveKeep、コインゲームコレクション、Himekuri、OshiLog、あなたレシート。新規ダウンロードは4件から29件、5本合わせて56件。売上は1円も立っていない。DiveKeep, Coin Game Collection, Himekuri, OshiLog and YOU Receipt. New downloads ranged from 4 to 29, 56 across all five. Not a single yen in sales.

分析Analysis

372,319円。前月から8.9%増えて、4ヶ月続けて月30万円台に乗りました。

増えた分はほとんど広告です。AdMobが167,118円で、うんちくんのiOSだけで128,666円。表示回数は867,281回まで伸びました。広告の月収としては2019年7月に初めて21円を受け取ってから3番目に高い月で、上回っているのは推しアイランドがバズった今年3月と、2022年3月の2回だけです。

面白いのは、新しく入れてくれた人が増えていないことです。うんちくんの新規ダウンロードは6月の32,412件に対して7月は32,579件。App Store全体でも39,240件から38,972件で、ほとんど動いていません。それでも広告の表示回数は16%伸びました。増えていたのは再ダウンロードのほうで、21,681件から54,873件へ2.5倍になっています。機種を変えたか、一度消してまた入れ直したか。どちらにしても、すでに知っている人が戻ってきて、前より多く開いた月でした。

課金は195,845円で横ばいです。広告は既にいる人の利用が増えれば伸びますが、課金はそうはいかない。今月の形はそこに出ています。

もうひとつ、集中の度合いが気になります。うんちくんと旅行思い出マップの2本で月収の84%。7月は新作を5本出しましたが、売上はどれもゼロで、ダウンロードが2桁に届かないものもありました。出す手は止めません。ただ、出しただけでは何も起きないと数字がはっきり言っています。

$2,324. Up 8.9% from last month, the fourth straight month in the $1,872 range.

Almost all of the increase is ads. AdMob was $1,043, and UNCHIKUN on iOS alone made $803. Impressions grew to 867,281. It's my third-highest ad month since I received my first 21 yen (about $0.19) in July 2019. The only two months above it are this March, when Oshi Island went viral, and March 2022.

The interesting part is that the number of new people installing didn't grow. UNCHIKUN's new downloads were 32,412 in June and 32,579 in July. Across the whole App Store, they went from 39,240 to 38,972, barely moving. Yet ad impressions grew 16%. What grew was redownloads, 2.5x from 21,681 to 54,873. People either changed phones or deleted the app and installed it again. Either way, it was a month when people who already knew the app came back and opened it more than before.

Purchases were flat at $1,222. Ads grow when existing users use the app more, but purchases don't work that way. That's what this month's shape shows.

One more thing bothers me: how concentrated it is. UNCHIKUN and TravelMemoryMap made 84% of the month's revenue between them. I released 5 new apps in July, every one of them made $0, and some didn't even reach double-digit downloads. I'm not going to stop shipping. But the numbers say plainly that shipping alone makes nothing happen.

NextAction

この数字を見て、来月やることを3つ決めました。Based on these numbers, I picked three things to do next month.

  1. うんちくんの広告フォーマットを見直す。eCPM148円が1割上がるだけで月1万円以上変わるReview UNCHIKUN's ad formats. Raising the $0.92 eCPM by just 10% changes revenue by more than $62 a month
  2. うんちくんのペイウォールを出す場所を変えて、増えたダウンロードを課金につなげるChange where UNCHIKUN's paywall appears, to turn the extra downloads into purchases
  3. 7月に出した5本のうちダウンロードが動いているものだけに絞って、ASOをやり直すOf the 5 apps released in July, narrow it down to the ones whose downloads are moving and redo their ASO

出した本数より、届いた一本。8月はそこを詰めます。Not how many I shipped, but the one that reached people. That's what I'm working on in August.

それでは、また来月の報告で。See you in next month's report.

数値について。AdMobは管理画面の推定収益額で、確定額とは数%ずれることがあります。App Storeは手数料を引いた開発者受取額で、外貨分は月末レートで円に換算した概算を含みます。Google Playはサービス手数料を引いた受取額です。3つとも暦月の1日から末日で区切っています。App Store Connectの財務報告はAppleの会計月で締めるので、同じ月でも対象期間がずれ、画面に出る金額とは一致しません。締め日の関係で、実際の振込額とも一致しません。
About the numbers. AdMob figures are the estimated earnings shown in the dashboard and can differ from the finalized amount by a few percent. App Store figures are developer proceeds after Apple's commission, and include estimates where foreign-currency sales were converted to yen at the month-end rate. Google Play figures are proceeds after the service fee. All three are cut by calendar month, from the 1st to the last day. App Store Connect's financial reports close on Apple's fiscal months, so the period covered shifts even for the same month, and the amounts won't match what's shown there. Because of payment cutoff dates, they won't match the actual payouts either. Dollar amounts are converted from yen at the ECB month-end rate (¥160.24 per US dollar on 2026-07-31), and every figure in this issue, including last month's, uses that same rate.
