うさポ by クラシル

The app opens to a bottle that fills up as you move or wait.

You see a glass bottle on the screen with a progress bar inside it. The bottle fills based on two things: how far you travel and how long you stay in one place. Travel distance uses your phone's GPS. The app asks for location permission the first time you open it. If you deny it, the travel bar does not move. The time bar keeps filling regardless of location access. You can switch between three speed modes: normal, double, and triple. Triple speed fills the bottle three times faster, but it also drains the bottle three times faster when you claim coins. The game does not explain this trade-off clearly.

The interface is minimal. A coin counter sits at the top. A claim button sits below the bottle. You tap claim when the bottle is full, and the coins go into your balance. The bottle resets and starts filling again. The cycle repeats indefinitely. You can also play mini-games to earn extra coins. These games are simple: a scratch card, a fortune teller, a slot machine. Each game costs a small number of coins to play and gives a random reward. The reward is usually less than the cost. The games exist mainly to show ads. Every game session triggers a video ad that lasts fifteen to thirty seconds.

The travel tracking and the idle timer compete for your attention in different ways.

Travel tracking requires active movement. You need to carry your phone while walking, driving, or taking public transport. The GPS updates every few minutes and adds distance to the bottle. The idle timer works in the background. You can leave the phone on a table, and the bottle still fills. This creates a system where you earn points whether you are active or passive. The trade-off is that travel tracking drains the battery faster and requires location permission. The idle timer is battery-friendly but slower. The triple speed mode applies to both, but it accelerates the drain on both the bottle and the battery. One user reported that 10,000 steps gave 1,100 coins, but then all coins disappeared due to a glitch.

The coin exchange rate is 100 coins to 1 yen equivalent. You can exchange for PayPay, Amazon gift cards, Rakuten points, d Points, Ponta Points, and nanaco Points. The exchange process requires phone number verification. Some users reported issues with the verification, where the system says the phone number is already in use. The exchange takes up to three days to process. The app does not offer instant exchanges. The rewards page shows a list of available options with their coin costs. The minimum exchange is typically 500 coins for a 5 yen equivalent reward. The maximum varies by reward type.

The version history shows regular updates but no detailed changelog.

The Play Store listing shows version 1.8.22 as the latest. APK mirror sites list versions 1.8.21, 1.8.16, 1.8.12, 1.8.8, 1.8.6, 1.7.8, and older. The file size varies from 103 MB to 114 MB depending on the version. The changelog for each version says the same thing: "機能の改善と軽微な不具合の修正をしました。" (Feature improvements and minor bug fixes.) No specific bug fixes are ever named. Users continue to report the same issues across versions: ads that are slow to close, coins that do not accumulate correctly, and location tracking that sometimes fails. The developer, Kurashiru Inc., is based in Tokyo, Japan. The same company also operates "Kurashiru" (a recipe app) and "Reshi Challenge" (a receipt-based point app).

The invite code system gives new users 5,000 bonus coins on registration. Codes are shared on social media and blogs. The codes are single-use and expire after a certain period. The referral program encourages users to share the app with others. The app's growth strategy relies heavily on this referral system and on ad revenue. The ads are the primary monetization method. The app shows ads after every mini-game, after every coin claim, and occasionally during idle periods. Users have described the app as "an ad simulator with a point system attached". The ad frequency is one of the top complaints in reviews.

The location permission is required for travel tracking, but the app also tracks your location in the background.

The app requests location access "all the time" to track travel distance. This means the GPS stays on even when the app is in the background. The privacy policy states that location data is shared with third parties for ad targeting. The app does not encrypt this data. Users concerned about privacy can disable location access and rely solely on the time-based accumulation. However, this cuts the earning potential roughly in half. The app does not offer a step-counting feature as an alternative to GPS. Unlike other point apps that use pedometer data, Usapo relies entirely on GPS for movement tracking.

The app size for the latest version is approximately 111 MB. The minimum Android version required is 6.0 (API 23) for older versions, and Android 12 for newer versions. The APK is available in XAPK format on some sites, which requires a special installer. The app supports both ARM and x86 architectures. The installation process is standard: download the APK, enable "Install from unknown sources", and run the installer. The app does not require root access. It does request storage permission to save game data, but this is optional. The storage permission is not required for core functionality.
