Tracking one thing
Track When You Last Changed Your Razor Blade
A razor-blade tracker answers a small memory question: when did I last replace this blade? Wen records the completed change and keeps it available to the people who need it. It does not inspect a blade or decide what is right for your skin.
Record the blade that actually changed
Keep the record specific enough to recognize later, especially if a household has several razors or cartridge types.
- Name the person, razor, or cartridge system clearly.
- Mark the replacement after the new blade is fitted.
- Keep different razors on separate records when their use differs.
- Use a reminder as a prompt only, separate from the factual replacement history.
Why the replacement date disappears
A blade is often replaced without a note, receipt, or message. Later, the question returns when the last cartridge was installed. One timestamp can preserve that answer without turning shaving into a routine you have to manage in detail.
Separate records are useful when one person uses more than one razor, or when a household buys replacement cartridges for several people.
What replacement guidance can and cannot say
The American Academy of Dermatology Association advises replacing a disposable razor after five to seven shaves in guidance about reducing razor bumps. That is context-specific dermatology guidance, not a universal Wen rule or a promise about every razor.
Individual skin, hair, blade design, storage, and personal preference can all affect the decision. Wen can preserve the date you chose to replace a blade, but it cannot assess comfort, sharpness, irritation, or shaving quality.
Track a confirmed change, not an estimate
If you do not remember the previous replacement, start with the next confirmed change. A future reminder can prompt you to inspect the razor, but it should not rewrite the date on which the blade was actually replaced.
Use product instructions or a qualified professional for personal skin or shaving questions. The app remains useful for the simple household record.

How Wen helps with razor changes
Wen gives a razor or cartridge a plain Sticker, a last-tracked time, and a factual history. You can record a replacement once and check the same answer later without relying on memory.
- Create a Sticker for the specific razor or person.
- Mark it when the blade or cartridge is replaced.
- Check Last Tracked when you want to know when it happened.
A replacement record, not shaving advice
Wen does not recommend a blade interval, inspect blade condition, assess skin, or promise to prevent irritation or injury. Follow the product instructions and seek appropriate professional advice for individual skin or shaving concerns.
