About

Angle Gradient Inclinometer

Easily measure tilt angles with this free protractor app. It displays inclination from 0 to 359 degrees, along with gradient percentages and angles summing to 180 or 360 degrees. Switch to theodolite mode to set a specified angle to zero.

Highlights
  • Measure tilt angles 0-359 degrees
  • Display gradient percentage
  • Show sum angles (180/360)
  • Theodolite mode
  • Set specified angle to zero

Simple tilt angle protractor free application that can easily measure tilt simply by tilting the device. The angle of inclination measured from 0 degree to 359 degrees, converted gradient (%), angle at which sum is 180 degrees / 360 degrees are displayed at the same time. You can switch to the theodolite, the specified angle can be set to 0 degree. ( 45 Degrees = Gradient 100 % )

About

TOIVIS

Visual inspection, powered entirely on your iPhone. TOIVIS learns what “normal” looks like from images of good products, then helps you inspect new images and visualize differences. It combines on-device DINOv2, SubspaceAD, ROI-based alignment, and heatmaps—without requiring a network connection or uploading your inspection images to a cloud service. KEY FEATURES Learn from good samples Register 4–20 normal images for each product. Inspect the full image or define one region of interest. See where something changed Review deviation scores and heatmaps to locate areas that differ from the learned normal state. Align before you decide TOIVIS matches each inspection image against a master and compensates for position, rotation, scale, and perspective. When image quality or alignment is insufficient, the app holds the decision instead of forcing a pass or fail. Choose from three inspection methods Inspect saved images, capture a single image on the spot, or keep the camera open for continuous line inspection. Keep an auditable record Store the decision, source image, heatmap, Capture Quality, Match Score, model revision, and operator confirmation. Export individual or batch PDF reports and CSV history. Review performance by product Use physically verified labels to review a confusion matrix and key metrics by product, period, and model revision. Start with a guided demo A 10-minute Quick Guide and detailed tutorial use bundled industrial images so you can experience the real on-device AI workflow before registering your own product. OFFLINE BY DESIGN Normal-model training and inspection run on device. Product images, models, and inspection history stay on device and can be exported as a backup archive. IMPORTANT Detection performance varies with the product, lighting, camera position, normal-image quality, inspection region, and thresholds. Validate TOIVIS with representative products under real operating conditions, and follow your organization’s quality procedures for final decisions. iPhoneだけで、外観検査をもっと身近に。 TOIVISは、製品のOK画像から「正常な状態」を端末内AIが学習し、撮影した画像との違いを可視化する外観検査アプリです。DINOv2とSubspaceAD、ROI位置合わせを組み合わせ、ネットワークに接続せずに検査できます。画像やモデルをクラウドへ送信する必要はありません。 【主な機能】 ・OK画像から正常モデルを作成 製品ごとに4〜20枚のOK画像を登録。画像全体、または1つの検査範囲(ROI)を設定できます。 ・異常箇所を見える化 逸脱度とヒートマップで、正常状態との違いが現れた場所を確認できます。 ・安定した位置合わせ マスタ画像と検査画像を照合し、位置・回転・拡大縮小・遠近のずれを補正。画質や位置合わせが不十分な場合は、無理に合否を出さず「判定保留」にします。 ・現場に合わせた3つの検査方法 保存済み画像、その場で1枚撮影、ラインでの連続撮影に対応。作業に合った方法で検査できます。 ・結果を記録・共有 検査履歴に判定、元画像、ヒートマップ、Capture Quality、Match Score、モデルRevisionなどを保存。結果はPDFまたはCSVで書き出せます。 ・製品別の精度確認 実物確認済みのラベルを使い、製品・期間・モデルRevisionごとに混同行列や検出率などを集計できます。 ・はじめやすいガイド 同梱の実写画像を使った10分クイックガイドと詳細チュートリアルを用意。自分の製品を登録する前に、端末内で実際のAIフローを試せます。 【オフライン設計】 正常モデルの作成と検査は端末内で実行されます。製品画像、モデル、検査履歴も端末内に保存され、バックアップ用のアーカイブとして書き出せます。 【ご利用にあたって】 検出性能は対象物、照明、撮影姿勢、正常画像の品質、検査範囲、しきい値などにより異なります。導入前に実際の製品と現場条件で検証し、最終判断は現場の品質基準に従ってください。

Verdict

The call

The clearest difference is ads: TOIVIS at none against Angle Gradient Inclinometer's shown. TOIVIS also leads on update cadence (every 4 days vs every 8 months). Angle Gradient Inclinometer's advantage is iOS requirement (13 vs 17.0). On price, in-app purchases and device support there is nothing between them.
