機能劣化

有料版に、当初あったメモリ解放機能、CPUのクロック周波数確認機能が、使用できなくなった。
返金して欲しい。

old widgets are gone!

with the new update the old widgets on the botton of the widgets view in the left side of the home screen are gone,please get it back i really like it

ついについにUpdate !

ストアでの表記は5.0ですが実際はver5.0.5です。app紹介のiPhoneスクショは旧verのままですが、、安心してください🙂ちゃんとモダンになってました🎵しかも使い勝手はほぼ前と同じです。しばらく使っていない方は、当appの設定>アップデートでデータをダウンロードしておきましょう。(ios18.7&26.0)

久しぶりに触りましたが、ツール>comparison(比較)はデータ抜けがまだまだ有りますが、timeline(製品履歴)の作り込みはなかなかおもしろでした。結論:製品仕様データベースとしてはMactrackerしか選択肢が無いのが現状。

Thanks, Hirooka-san !

待望のアップデート&メモリブーストができなくなった

もうアップデートされないものだと思っていたので突然のアップデートに喜んでいます。ただ、一番重宝していたメモリブースト機能が消えてしまって戸惑っています。今後再追加される予定はあるのでしょうか?

念のため、Premium Status: unlocked (full version),
Lifetime access: active

Lirum is back, baby!!

I’ve been having to dismiss “Model not yet found in our database” for about 7 years now, but today it has been updated! I hope other apps that have been abandoned make a comeback as well. Thank you for reviving support for this fantastic app!

FAQ

What kind of system activity does this app show?

The app displays real-time CPU activity and approximate system-wide memory usage. It also shows the battery level and charging state directly from iOS. Additionally, you can view live data from sensors like the accelerometer, gyroscope, magnetometer, and barometer.

What device specifications can I find in this app?

You can access published device specifications sourced from Apple's Tech Specs for each model. This includes details such as dimensions, weight, display resolution, supported wireless bands, and environmental limits.

Is this app free to use?

Yes, the application is available for free. There are no in-app purchases or advertisements mentioned in the provided data.

What information does the app NOT provide?

The app intentionally does not offer diagnostics or hardware health assessments. It also does not provide battery wear, voltage, cycle count, or time-remaining estimates. Furthermore, it does not include memory 'optimizers' or performance-boosting claims.

What are the privacy implications of using this app?

Sensor and network data are processed and displayed on-device only. Location data, if permission is granted, is used solely for displaying location and accuracy and is not stored or transmitted elsewhere.
