Procrastinated? You can still restart. DelayLens is a gentle tool for the moment after you realize you got stuck. Instead of asking you to become perfectly disciplined, it helps you record what happened, name the cause, choose the smallest next action, and return to focused work. It is not a generic Pomodoro timer, to-do list, or habit tracker. DelayLens is built around one clear recovery loop: record → understand → take one small step → focus → learn from what helped. HOW IT WORKS 1. Record the procrastination Start a log when you notice you are putting something off. End it when you are ready to come back, so the time that actually passed is captured. 2. Name what got in the way Choose a reason, add a task category, and leave a note if useful. A task may feel too large, the first step may be unclear, or you may be tired or distracted. Recording the cause turns a vague feeling into something you can review. 3. Choose one small next action Replace “finish the report” with “open the document and write the title.” Make the next move specific enough to begin. 4. Choose a restart method and focus length Pick a restart method that fits the moment, then focus on the next action for 5, 15, or 25 minutes. When it ends, decide what comes next. 5. Learn what helps you restart Review procrastination time, causes, restart methods, completion, and your own feedback. Over time, DelayLens can compare which methods are associated with more completed actions and provide method-based insights and personalized suggestions from your records. WHAT DELAYLENS HELPS YOU DO • Log procrastination time as it happens • Record reasons, categories, and notes • Turn a stuck task into a small next action • Follow small steps during a 5, 15, or 25 minute focus session • Use different restart methods and keep a record of what you tried • Review daily and weekly trends • Bring today’s procrastination and focus together in a daily reflection • Leave feedback on what helped • See method effectiveness and personalized suggestions based on your records • See the link between a procrastination log and the focused action that followed FREE AND PRO The free experience helps you complete the restart in front of you: log the episode, understand the cause, choose a next action, focus, and review today or this week. DelayLens Pro adds longer-range views and deeper pattern insights, including method effectiveness and personalized suggestions based on your recorded completion and feedback patterns. MADE FOR REAL-LIFE STARTING TROUBLE DelayLens can help when: • You know you should study but have not opened the material • A work task feels too large to begin • You are tired but still want to move forward a little • The same kind of procrastination keeps returning DelayLens does not promise to eliminate procrastination or complete your work for you. It gives you a calmer way to acknowledge what happened and begin again. Start with one small action.

Guyun keeps your files in object storage you own: Alibaba Cloud OSS, Tencent Cloud COS, Qiniu, Upyun, Backblaze B2, Cloudflare R2, MinIO, or any S3-compatible service. No account system, no server of ours, no telemetry — files go straight from this device to your own bucket. The app provides no cloud space and takes no cut of your storage. ■ Why "your own storage" Most cloud drives keep your files on the vendor's servers, which decides the speed, the capacity and the price. Guyun is the other way round: the bucket, the keys and the bill are yours, and your provider bills storage and traffic at its published rates. Guyun never bills you for either. ■ What it does · Browse and manage: grid or list, sorted by name, date or size; whole-bucket search, not just the folder you are in; new folders, rename, copy, move · Upload and download: from Files or Photos, or a whole folder at once, through a queue you can pause and resume; downloads go to a folder or to Photos · iOS background transfers: files up to 200 MB go to the system as one request and finish even if you switch apps or lock the screen; larger files continue with the background time granted · Progress anywhere: a small pill shows how many transfers are running and how far along they are · Usage ledger: how much Guyun itself moved — today, this month and last month, by bucket and by device, with cellular counted separately on this device. Only this app's transfers, never your provider's bill · Storage size: measure a bucket to get its file count and total size; a large bucket can be finished over several taps, and the result stays on this device · Archive files are marked; the app asks before a restore (how long, billed by your provider, cannot be cancelled), and afterwards preview and download work as usual · Preview: zoom images, play video while it is still loading, open PDF and text · Trash: a delete moves the item to the bucket's own trash folder, where it can be restored or removed for good · Several devices: the same bucket on iPhone, iPad and Mac; hand a configuration over by scanning a code instead of typing keys · Make it yours: an icon per storage, a sidebar you can reorder, and storages you do not need hidden away (back in Settings → Storage service) · Locks: Face ID / Touch ID for the whole app or one storage; transfers keep running while locked, and turning a lock off always asks for authentication first ■ Privacy, in plain terms · No account and no server of ours: the app talks to the storage address you enter, and to nothing else · Access keys live in this device's Keychain, never uploaded to us and never synced through iCloud · Keys leave the device only when you deliberately hand a storage to another device: the handoff code contains them in plain text, so show it only to your own device and treat it like a password · No usage data collected; no third-party SDKs, no analytics, no ads · Face ID / Touch ID is handled by the system, and that data never leaves your device · Both locks are screen gates, not encryption: they keep out someone who picks up your unlocked device ■ Try it without any storage A local demo storage is built in: sample photos, a video and a PDF are generated on device. No account, no keys, no network — browse, preview, upload, rename, copy, move, delete and restore, all without a single credential. ■ What you need A bucket, and a key pair allowed to use only that bucket. Pick the service and place and the app fills in the endpoint and region; you enter the bucket name and the keys (Tencent COS also asks for the APPID ending its bucket names). Guides for every service are on our website, including an Alibaba Cloud template that creates the bucket, the RAM user and the keys at once. ■ Languages Simplified Chinese, Traditional Chinese and English (switch in Settings; applies next time you open the app).

Verdict
The clearest difference is in-app purchases: Guyun at none against DelayLens's 3. Guyun also leads on update cadence (weekly vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.
