OJI AI Video & Photo GeneratorOJI AI Video & Photo GeneratorProblème UX

Inaccurate & Low-Quality AI Output

Users consistently report that AI-generated images and videos do not resemble their input photos, often appearing distorted, generic, or completely irrelevant. Issues include incorrect skin tones, facial features, hair, and even generating entirely different subjects or themes. Many feel it's just basic face-swapping rather than true AI transformation.

Unreliable AI Output & Poor Context Memory

Users report AI generating fake/inaccurate responses, especially when rushed, and failing to retain conversation context or user-specific information over time. This makes the app unreliable for serious work and frustrates users who expect consistent, personalized interactions. The AI also struggles to see real-time messages.

Ineffective Search & Filtering

Users struggle with the app's search functionality, which often provides irrelevant results (e.g., global instead of local) and lacks robust filtering options. Essential filters like 'actual ratings,' 'hotel class,' or specific amenities are either missing, don't work, or reset frequently, requiring repetitive input.

Confusing & Unintuitive User Interface

Users find the app's interface difficult to understand and navigate. Complaints include too many settings, non-responsive controls, unintuitive workflows (e.g., saving requiring multiple steps or going back and forth), and recent updates making the UI worse.

Core Content & Features Removed/Degraded

Users are highly dissatisfied with the removal of popular movie clips, diverse GIFs, and unique features like voiceover/lip-sync, which were central to the app's appeal. This content has been replaced with generic, low-quality, or less engaging AI-generated alternatives, severely diminishing the app's value and fun.

Inaccurate & Unrealistic AI Generations

Users report that AI-generated images, particularly face swaps, often do not resemble them, add unwanted features (like hair to bald heads), or result in pixelated, cartoonish, odd, or uncanny outputs. The quality has reportedly degraded with recent updates, making the results less realistic than before.

Unreliable Password Saving & Sync

Users frequently report that the app fails to save newly created or updated passwords, or it saves incorrect/old versions, leading to lockouts and frustration. Synchronization across multiple Apple devices is inconsistent, and some users have reported losing all their saved passwords.

AI Fails to Follow User Instructions

Users are frustrated that the AI photo editor does not reliably execute their commands, often producing results that are irrelevant or even contrary to their explicit instructions. This fundamental lack of responsiveness makes the app unusable for its intended purpose.

Degraded/Removed Core Content & Features

Users are frustrated by the removal of popular movie clips, specific GIFs, voice features, and the ability to upload their own videos/GIFs for face-swapping. The current content library is perceived as generic, cringe, or inappropriate, significantly reducing the app's appeal and utility.

Ineffective Photo Enhancement Quality

The app's AI photo enhancement feature fails to deliver on its promise, with users reporting that images remain blurry or out of focus even after applying the enhancement. This indicates a significant quality gap in a key editing function that users expect to work effectively.

Widgetable: Besties & CouplesWidgetable: Besties & CouplesProblème UX

Picky Pets & Emotionally Manipulative Design

Pets are overly picky, often demanding specific or premium foods and refusing available alternatives. The app's design uses emotional manipulation (pets getting sad, leaving with guilt-tripping notes, or being difficult to retrieve) to pressure users into constant engagement or payment, causing stress and negative emotional impact, especially for children.

Poor UX/UI & Guidance

Users are frustrated by confusing navigation, clunky interfaces, and a lack of clear guidance during workouts. Specific issues include unrealistic/misleading visuals, unclear exercise illustrations, and a recent update removing verbal cues, forcing users to constantly look at their screen. The onboarding process is also criticized for being too long and forced.

No Free Trial or Demo

Users are unable to test the app's core AI generation features before committing to a subscription. Many reviews highlight deceptive 'Try' labels that lead directly to paywalls, creating frustration and distrust. Users want to evaluate the quality and functionality of the AI before paying.

Poor User Experience & Navigation

Many users encounter blank screens, get stuck on a single password entry, or find the app's navigation confusing. The forced migration from Settings to a standalone app is disliked, with users feeling it's less secure and harder to find. Basic UX elements like searching for non-contiguous letters or copying passwords are also frustrating.

广告无法关闭,导致应用无法使用

许多用户反映应用内广告的关闭按钮(“X”)经常被手机状态栏(如电池、Wi-Fi图标)遮挡或无响应,导致广告无法跳过。这使得用户在观看广告后无法继续使用应用,严重影响了免费用户的使用体验。

Unrealistic Pet Care Demands & Food Scarcity

Users struggle to keep virtual pets fed and cared for due to insufficient free food, long cooldowns on earning items, and the sheer volume of resources needed for multiple pets. This leads to pets 'running away' and significant user frustration and guilt.

Missing Multimodal Input & Key Integrations

Users frequently complain about the absence or malfunction of core features like image upload and image generation, which are often advertised. There's also a desire for specific AI model integrations (e.g., Gemini live chat, Pie AI) and general integration with other apps/services (e.g., PPT download).

Lose It! – Calorie CounterLose It! – Calorie CounterFonctionnalité manquante

Inaccurate & Uneditable Food Database

Users consistently report wildly inaccurate calorie and nutritional values for both generic and brand-name foods, often with multiple conflicting entries. The inability to edit or correct these values, especially for scanned items, makes accurate tracking impossible and undermines the core purpose of a calorie tracker.

Rigged Games & Misleading Rewards

Users are consistently frustrated by in-app games and 'free gift' promotions that appear to be rigged, making it nearly impossible to win or redeem promised rewards. Points and credits often expire quickly, disappear, or require an unreasonable number of invites, leading to a feeling of being scammed.
